1. Cleverly

Cleverly specializes in B2B cold email campaigns with particular strength in LinkedIn lead generation. 

Founded on data from thousands of successful B2B email marketing campaigns, the agency combines automation with genuine personalization (not the “Hi {First_Name}” everyone sees through).

What separates Cleverly from other email marketing agencies is its LinkedIn focus. If your customers scroll LinkedIn between Zoom calls, Cleverly knows how to reach them. 

They handle everything from identifying decision-makers to running A/B tests. 

Past clients reported 56 meetings in nine months for a healthcare company while maintaining a 31% reply rate — beating industry averages comfortably.

Key services offered

Cleverly takes a done-for-you approach:

  • AI-powered personalization beyond basic mail merge
  • Qualified lead list building focused on decision-makers
  • LinkedIn lead generation with personalized email follow-ups
  • Real-time performance tracking through easy-to-use dashboards
  • Dedicated email inbox and domain setup protecting your sending reputation
  • Data-driven cold email campaigns using insights from thousands of B2B outreach efforts

Pricing

Cleverly uses a pay-per-meeting-ready-lead model, aligning their success with yours (they only get paid when you get qualified leads). 

Pricing is customized based on leads needed and outreach volume. The minimum budget starts at $1,000 monthly, though highly customized solutions require consultation.

One advantage — month-to-month services with no long-term contracts, so you’re not locked in if results disappoint. 

Their average hourly rate falls between $25-$49, and most projects land under $10,000. They offer volume discounts for larger teams.

Pros & cons of choosing Cleverly

Here are some advantages and disadvantages of choosing this cold email marketing agency:

ProsCons
Perfect for LinkedIn-focused B2B lead generationPricing not transparent upfront
Strategies backed by data from thousands of campaignsSome users report miscommunication or execution delays
Strong campaign management with AI personalizationRecent reviews mention lead quality consistency concerns
Flexible month-to-month contractsLimited campaign customization noted by clients

What users say

Cleverly earned strong ratings: 4.6/5 on G2, 4.8/5 on Trustpilot, and 5/5 on Google. 

Users praise the platform’s ability to automate LinkedIn connections while securing meetings quickly. One client mentioned their account executives “fight over Cleverly leads,” while another called it the “single best outsourced prospecting service” they’d used.

Recent feedback shows mixed results. Some reports lead to quality issues and inadequate support. 

A few mentioned data security and execution reliability concerns, so we have detailed conversations during onboarding about quality standards and communication protocols.

2. Belkins

Belkins positions itself as a premium B2B email marketing agency specializing in ROI-focused lead acquisition. 

Unlike agencies that spray-and-pray, Belkins emphasizes customized outreach where every email receives genuine personalization (they hand-craft messages rather than relying purely on templates).

The agency targets mid-to-large enterprises with complex sales cycles. 

Their omnichannel approach integrates email, intent calling, and LinkedIn — covering all bases where prospects spend time. 

If you need 200 to 400+ appointments annually with detailed lead profiles, Belkins builds systems to deliver consistently.

Key services offered

Belkins provides full-service experience:

  • Personalized outreach tailored to specific audiences
  • Deliverability auditing keeps emails out of spam folders
  • Comprehensive lead research with detailed profiles and verified data
  • Sales enablement, empowering teams with the right tools and training
  • Full email campaign management, including content creation and optimization
  • Omnichannel appointment setting projecting 200-400+ appointments annually

Pricing

Belkins follows customized pricing reflecting their focus on large, tailored campaigns. Plans depend on appointments delivered, lead research depth, and campaign management services. 

They offer two main packages: 

Omnichannel (targeting 200+ booked appointments yearly and up to 20,000 curated leads annually) and Omnichannel Plus (targeting 400+ appointments yearly and up to 50,000 curated leads yearly).

The minimum project cost is $10,000+, with an hourly rate under $25. Most projects fall between $10,000 to $49,000. 

This pricing reflects their premium positioning. 

Small businesses might find the investment steep, but mid-to-large enterprises often see strong ROI given lead quality and volume.

Pros & cons of choosing Belkins

Here are some advantages and disadvantages of choosing this cold email marketing agency:

ProsCons
Highly targeted and customized outreach strategiesExpensive for small businesses
Proven track record delivering consistent, high-quality leadsOccasional miscommunication during execution reported
Perfect for mid-to-large enterprises needing omnichannel strategiesRequires consultation for pricing details
Comprehensive lead research with detailed profilesHigh minimum investment may exclude smaller companies

What users say

Belkins maintains impressive ratings: 4.8/5 on G2 (from 89 reviews), 4.9/5 on Clutch (from 221 reviews), and 9.9/10 on Trustradius. 

Clients praise their tailored strategies, hands-on approach, lead quality, and ability to simplify sales funnels. 

One reviewer noted Belkin’s “elevated our business game with tailored strategies and excellent communication.”

Users appreciate that, although pricing is high, it delivers a strong ROI through quality leads. 

However, a few noted response rate challenges and occasional miscommunication. 

If considering Belkins, establish clear communication channels and success metrics upfront to avoid misalignment.

3. SalesHive

SalesHive combines AI-powered email campaigns with human cold calling — reaching prospects where they’re most responsive. 

The agency specializes in B2B lead generation using proprietary technology and experienced Sales Development Reps who navigate gatekeepers and objections.

What makes SalesHive stand out is its eMod customization engine, which creates highly personalized emails by pulling public information about prospects (recent funding announcements, job changes, company milestones). 

Rather than sending generic templates, they reference specific details showing you’ve done your homework. Their process covers the full spectrum: 

  • Handling objections
  • Sending personalized emails
  • Building validated prospect lists
  • Booking meetings directly with your reps.
  • Setting up and authenticating email accounts
  • Warming them properly (critical for email reputation)

Key services offered

SalesHive provides comprehensive execution:

  • Custom sales playbook development tailored to your product and market
  • Objection handling and calendar coordination booking qualified meetings
  • Email account setup, authentication, and warming protecting deliverability
  • Cold calling with dedicated US-based callers (on Growth and Crush plans)
  • Validated prospect list building, reducing bounce,s and improving targeting
  • AI-powered email campaigns using their proprietary eMod personalization engine

Pricing

SalesHive offers transparent tiered pricing based on estimated meetings per quarter, with lower rates for six-month commitments.

Starter Plan: $4,000/month (with a six-month commitment) or $4,500 month-to-month. Includes phone or email outreach (you choose one), 150+ touches per day, and one dedicated US strategist. Estimated results: 20-30+ meetings per quarter.

Growth Plan: $7,200/month (with a six-month commitment) or $8,000 month-to-month. Includes phone and email outreach, 250+ touches per day, one dedicated US strategist, and one dedicated US cold caller. Estimated results: 40-55+ meetings per quarter.

Crush Plan: $10,800/month (with six-month commitment) or $12,000 month-to-month. Includes phone and email outreach, 500+ touches per day, one dedicated US strategist, and two dedicated US cold callers. Estimated results: 60-90+ meetings per quarter.

All plans include eMod personalized emails, risk-free onboarding, and custom sales playbooks. The transparency is refreshing — you know exactly what you’re getting before signing.

Pros & cons of choosing SalesHive

Here are some advantages and disadvantages of choosing this cold email marketing agency:

ProsCons
Transparent tiered pricing with clear service breakdownsHigh barrier to entry at $4,000/month
AI-powered personalization through proprietary eMod technologyLimited independent user reviews available
Comprehensive service, including email setup and deliverabilityRequires a six-month commitment for lower pricing
Multichannel strategies combining phone and emailMonth-to-month option costs significantly more

What users say

While specific G2 or Clutch ratings weren’t readily available, SalesHive emphasizes its track record of setting over 85,000 B2B sales meetings. 

They direct potential clients to view testimonials on their Trustpilot account. 

The company’s longevity and client volume suggest consistent delivery, though request case studies specific to your industry during consultation calls.

Given the significant monthly investment, ask for references from similar companies before committing. 

The lack of extensive independent reviews shouldn’t be a red flag, but it means more due diligence upfront.

4. Pearl Lemon Leads

Pearl Lemon Leads focuses specifically on B2B lead generation through highly personalized cold email campaigns that provide genuine value (rather than “just checking in” messages cluttering inboxes). 

Their data-backed strategies help businesses connect with high-value prospects while maintaining strict compliance with email regulations like GDPR and CAN-SPAM — increasingly important as enforcement tightens.

The agency handles the complete campaign lifecycle, from domain warming and list validation to A/B testing and reporting. 

If you’re in a heavily regulated industry or selling to European markets where GDPR violations carry hefty fines, Pearl Lemon’s compliance-first approach offers peace of mind.

Key services offered

Pearl Lemon Leads provides end-to-end cold email services with compliance baked in:

  • Cold calling, supplementing email outreach
  • Cold email campaign development and execution
  • B2B lead generation focused on quality over volume
  • Demand generation and marketing automation setup
  • GDPR and CAN-SPAM compliance, avoiding legal issues
  • Domain warming and list validation protecting deliverability
  • A/B testing and performance reporting with actionable insights

Pricing

Pearl Lemon Leads doesn’t publish transparent pricing, requiring direct contact for tailored quotes based on your needs. 

Their advanced personalization features may come at a premium cost compared to automated agencies. 

This custom pricing model means smaller businesses might find services cost-prohibitive, while enterprises with larger budgets and complex compliance needs will likely find the investment worthwhile.

When reaching out, be prepared to discuss your target market, expected campaign volume, and industry-specific compliance requirements affecting scope and pricing.

Pros & cons of choosing Pearl Lemon Leads

Here are some advantages and disadvantages of choosing this cold email marketing agency:

ProsCons
Results-driven B2B lead generation approachPricing not transparent without direct contact
Strategies based on detailed data analysisAdvanced personalization features may cost premium
Compliant with major email regulationsLimited public information about pricing structure
Flexible campaign solutions across multiple industriesCustom pricing may price out smaller businesses

What users say

Pearl Lemon Leads maintains solid ratings: 4.8/5 on Google and 4.5/5 on G2. 

Users appreciate their focus on data-driven strategies and compliance, particularly businesses operating in regulated industries or targeting European markets. 

The agency’s ability to navigate complex compliance requirements while delivering results gets frequent mention.

However, the lack of pricing transparency frustrates potential clients who prefer evaluating costs before sales calls. 

If seriously considering Pearl Lemon, schedule a consultation with specific questions about pricing ranges, contract terms, and what’s included versus extra costs.

5. Agent Frank (from Salesforge)

Agent Frank represents a newer approach to cold email marketing: AI-driven automation replicating the effectiveness of human SDRs at a fraction of the cost. 

Developed by Salesforge, Agent Frank combines artificial intelligence with personalization features that adapt to prospects’ behavior and engagement patterns (learning what works and doubling down on successful approaches).

The platform is designed for businesses seeking automation with a human touch — messages that feel personal without requiring hours of manual customization. 

Agent Frank offers unlimited contact limits and auto-pilot modes simplifying operations significantly. 

If you’re a startup or small business that can’t afford a full sales development team but needs consistent outreach, Agent Frank delivers estimated savings up to 16x compared to hiring traditional SDRs.

Key services offered

Agent Frank provides automated solutions maintaining personalization quality:

  • Performance tracking and analytics dashboards
  • Campaign templates optimized through machine learning
  • AI-driven personalization adapting to prospect engagement
  • Integration with popular CRM systems (though some limitations exist)
  • Unlimited contact limits for aggressive outreach strategies
  • Auto-pilot campaign modes for simplified operations

Pricing

Agent Frank offers transparent, affordable pricing compared to traditional agency models. 

Starting at $499 per month, the platform represents significant cost savings — up to 16x cheaper than hiring full-time Sales Development Representatives. 

This makes it accessible for startups, small businesses, and solo entrepreneurs needing consistent outreach but lacking budget for expensive agency retainers or in-house hiring.

The straightforward pricing structure means no surprise fees or hidden costs. 

You know exactly what you’re paying monthly, making budgeting simple. 

For businesses with unpredictable cash flow or testing cold email as a channel, this predictability reduces financial risk.

Pros & cons of choosing Agent Frank

Here are some advantages and disadvantages of choosing this cold email marketing agency:

ProsCons
Affordable pricing compared to hiring SDRs or agenciesLimited integration options with some CRM tools
Combines AI-driven personalization with campaign automationRequires initial setup time to tailor campaigns
Simple and intuitive interface requiring minimal technical knowledgeLess hands-on support than full-service agencies
High efficiency ideal for businesses seeking automationMay lack nuance for complex B2B sales cycles

What users say

Agent Frank earned exceptional ratings: 4.9/5 on G2 and 4.8/5 on Product Hunt. 

Users consistently highlight ease of use, excellent customer support, and ability to maintain campaign quality while increasing volume. 

One user stated Agent Frank transformed their cold email strategy, allowing tasks that once consumed hours to be completed in minutes with better results.

The positive feedback centers on the platform’s balance between automation and personalization. 

However, if you’re selling complex enterprise solutions with six-month sales cycles, you might need more sophisticated nurturing than Agent Frank provides. 

For most B2B scenarios — particularly SaaS, agencies, and consulting — the platform delivers solid results at an unbeatable price point.

6. Growth.cx

Growth.cx specializes exclusively in B2B SaaS and tech companies, bringing deep industry expertise to cold email campaigns. 

Rather than being generalists working with any business that pays, they focus on specific challenges SaaS companies face: 

  • Technical buyers
  • Feature-heavy products needing careful positioning
  • Competitive markets where differentiation matters enormously
  • Long sales cycles

Their ROI-focused approach targets 10-15 high-quality meetings per month — not hundreds of tire-kickers, but genuine prospects matching your ideal customer profile with budget authority. 

Growth.cx creates personalized campaigns designed to connect with decision-makers in competitive tech industries where generic messaging gets ignored.

Key services offered

Growth.cx delivers specialized services tailored to SaaS and tech businesses:

  • Dedicated strategists providing one-on-one consultation
  • Campaign alignment with business goals and product positioning
  • Industry expertise focused on high-value B2B SaaS and tech leads
  • ROI-focused campaigns aiming for 10-15 high-quality meetings monthly
  • Personalized email outreach creating high-converting, customized messages
  • Services working for both early-stage startups and established SaaS companies

Pricing

Growth.cx operates on a customized pricing model with details available only through consultation. 

Pricing depends on your outreach volume, lead generation needs, target market complexity, and desired service level. 

Since they tailor solutions rather than offering cookie-cutter packages, expect pricing discussions after they understand your business thoroughly.

When requesting a quote, be ready to discuss your average deal size, sales cycle length, and target accounts. Companies with higher lifetime customer value typically justify larger investments in quality lead generation.

Pros & cons of choosing Growth.cx

Here are some advantages and disadvantages of choosing this cold email marketing agency:

ProsCons
Industry-specific expertise in B2B SaaS and techPricing not transparent without consultation
High ROI potential through measurable results and personalized campaignsServices limited to SaaS and tech-focused businesses
Dedicated support to refine strategies effectivelyBusinesses outside SaaS/tech will find services less relevant
Focus on quality meetings rather than vanity metricsCustom pricing may exclude smaller startups with tight budgets

What users say

Growth.cx maintains a 4.7/5 rating on Trustpilot, with clients praising their specialized approach and consistent results. 

Users particularly appreciate the ROI-driven focus and personalized strategies that speak the language of technical buyers. 

The agency’s ability to understand complex SaaS products and translate features into benefits that resonate with buyers gets frequent mention.

Client feedback emphasizes their effectiveness at scaling outreach while maintaining quality. 

If you’re a SaaS company tired of agencies that don’t understand your product or market, Growth.cx’s specialization could be exactly what you need. 

However, expect to invest time in onboarding so they can fully grasp your positioning and target accounts.

7. (310) Creative

(310) Creative operates as a full-service marketing agency with cold email as one component of their comprehensive approach. 

What distinguishes them from email-only shops is their use of intent data and website visitor tracking — identifying potential customers already showing interest in solutions like yours (dramatically improving conversion rates compared to cold prospecting random lists).

By tracking which companies visit your website, what pages they view, and how long they engage, (310) Creative identifies the warmest prospects and engages them through targeted email campaigns before competitors do. 

They combine cold emailing with other outreach channels, including social media, paid advertising, and cold calling, creating multiple touchpoints that increase response rates.

Key services offered

(310) Creative provides multichannel lead generation services:

  • Professional email design and A/B testing
  • Sales enablement and pipeline management support
  • Targeted cold email campaigns using data-driven insights
  • Website visitor tracking engages high-intent prospects early
  • Multichannel outreach, including social media, paid ads, and cold calling
  • Intent data utilization, identifying prospects actively researching solutions

Pricing

(310) Creative uses a performance-based pricing model structured in tiers based on estimated quarterly sales meetings.

  1. Growth Plan: $6,000/month, targeting 15-25 sales meetings per quarter.
  2. Enterprise Plan: $9,000/month, targeting 35-50 sales meetings per quarter.
  3. Basic/Startup Plan: $3,000/month, targeting 9-12 sales meetings per quarter.

The performance-based structure aligns their success with yours — they’re incentivized to deliver actual meetings, not just email sends or open rates. 

However, specific details about what’s included in each tier aren’t publicly available, so discuss specifics during sales conversations.

What users say

Specific client reviews and platform ratings for (310) Creative aren’t extensively documented in public sources. 

The agency maintains a presence but doesn’t have the volume of reviews found on G2 or Clutch compared to competitors.

This lack of extensive independent validation means you should request detailed case studies and references during evaluation. 

Ask for examples from companies in your industry with similar target markets and deal sizes. 

Before committing to multi-month contracts, clarify expectations around meeting quality, response protocols when targets aren’t hit, and what “meetings” actually mean (qualified discovery calls versus any calendar booking regardless of fit).

8. SalesBread

SalesBread takes an unusual approach in a world obsessed with volume: they deliver one curated lead per day, meticulously tailored to your specific target market. 

Instead of blasting thousands of emails hoping something sticks, they focus on deeply researched prospects who genuinely fit your ideal customer profile — then craft personalized LinkedIn messages and “warm emails” designed to start real conversations.

The agency specializes in manual personalization and multichannel outreach through email, social media, and personalized messaging. 

If you’re selling high-ticket products where each customer represents significant lifetime value, SalesBread’s quality-over-quantity approach often delivers better ROI than high-volume blasting.

Key services offered

SalesBread provides boutique-style lead generation focused on quality:

  • Prospect list building matching your ideal customer profile
  • Personalized LinkedIn messaging and warm email outreach
  • Manual personalization, maximizing engagement and relevance
  • Campaign strategy development aligned with your sales process
  • One curated lead delivered daily, tailored to your specific target market
  • Multichannel campaigns via email, social media, and personalized messaging

Pricing

SalesBread doesn’t publish pricing publicly, requiring direct contact for custom quotes based on your business requirements. 

Given their focus on manual personalization and curated lead delivery, expect pricing to reflect the labor-intensive nature of their approach.

Companies with high average contract values (think $10,000+ deals) will likely find the investment worthwhile, while businesses with lower-ticket offerings might struggle to justify the cost per lead. 

When requesting a quote, discuss your average deal size, sales cycle, and close rate so they can help you calculate expected ROI.

What users say

Client reviews and platform ratings for SalesBread aren’t extensively documented in readily available sources. 

The agency operates with a more boutique approach, which often means fewer but deeper client relationships rather than hundreds of accounts.

Before committing, request references from clients in similar industries selling comparable products. 

Ask about lead quality, response times, and how they handle situations when delivered leads don’t convert. 

Understanding their refund or adjustment policies when leads don’t meet quality standards will help you assess risk.

9. Martal Group

Martal Group brings serious firepower — over 15 years of experience, 2,000+ B2B brands served globally, and a proprietary AI sales platform monitoring 10 million+ intent signals. 

They specialize in scaling tech businesses through omnichannel campaigns launched via email, LinkedIn, and phone — hitting prospects across every channel they check daily.

The agency’s AI platform continuously refines campaigns based on performance metrics like subject lines, send times, and personalization approaches. 

Rather than setting campaigns and hoping for the best, the system learns from every interaction and adjusts strategies in real-time (similar to how paid advertising platforms work). 

Martal measures success by outcomes that matter: deliverability, engagement, and most importantly, qualified meetings.

Key services offered

Martal Group provides comprehensive B2B lead generation and sales services:

  • Real-time campaign refinement based on performance data
  • Omnichannel campaigns using email, LinkedIn, and phone outreach
  • Tier 1 service creating customized lists and delivering qualified leads to your CRM
  • Tier 2 service adding deal flow development, offer creation, and negotiation support
  • Tier 3 service, including account management and long-term strategy execution
  • Solutions from fractional support to fully outsourced sales teams
  • Proprietary AI sales platform leveraging 10M+ intent signals

Pricing

Martal Group offers flexible pricing models, including retainer-based, project-based (for one-off tasks like list building), and hybrid models combining fixed fees with variable components based on results. 

Their hourly rate ranges from $25-$49, with a minimum budget of $1,000+. Average project costs typically fall between $10,000-$49,000 based on Clutch data from 56 reviewed projects.

Specific monthly rates for Tier 1, 2, and 3 services aren’t publicly disclosed — prospective clients must request pricing directly. 

The flexible pricing structure accommodates different business needs and budgets. However, like many premium agencies, smaller businesses might find the investment steep.

Pros & cons of choosing Martal Group

Here are some advantages and disadvantages of choosing this cold email marketing agency:

ProsCons
15+ years of experience serving 2,000+ B2B brands globallySome feedback noted occasional misalignments with target profiles
Proprietary AI platform monitoring 10M+ intent signalsA few reviewers mentioned need for better data measurement
Omnichannel approach maximizing prospect touchpointsVariability in lead conversion rates reported
Flexible solutions from fractional support to full outsourcingPricing requires consultation

What users say

Martal Group maintains strong ratings: 4.8/5 on Clutch (from 99 reviews) and 4.6/5 on G2 (from 112 reviews) as a Premier Verified provider. 

Clients consistently praise their effectiveness, noting open rates exceeding 25% and well-qualified prospect calls generated faster than expected. 

Users highlight competitive pricing and strong value for money, with services fitting budgets while delivering quality results.

Reviews also emphasize their professionalism, effective communication, and quick responsiveness — they integrate as extensions of internal teams. 

However, some feedback mentions occasional misalignments with target profiles and variability in lead conversion rates, suggesting that thorough ICP documentation during onboarding is critical.

10. NerdyJoe

NerdyJoe specializes in tech and SaaS outreach with a radically different business model — you only pay for results. 

Instead of charging monthly retainers regardless of performance, they charge per lead or per meeting booked — aligning their incentives completely with your success (if they don’t deliver, you don’t pay).

The agency emphasizes deeply researched, hyper-personalized campaigns rather than high-volume blasting. 

They take an intensive approach to personalization, going far beyond basic LinkedIn scraping. 

Their team actively listens to podcasts prospects have appeared on, reads blog posts and social media content prospects have written, and reviews forum discussions prospects participate in — then crafts unique first lines referencing these insights.

Key services offered

NerdyJoe provides quality-focused cold email services for tech companies:

  • Campaign refinement based on the ideal customer profile
  • Hyper-personalization using psychographic data and extensive research
  • Pay-per-result pricing charges only for delivered leads or booked meetings
  • Deep prospect research, including podcasts, blog posts, social media, and forums
  • Focus on metrics that matter (qualified leads, meetings) over vanity metrics
  • Brand reputation protection, running campaigns with your domain

Pricing

NerdyJoe employs a transparent, performance-based pricing model, charging only for results rather than services rendered. 

Their “Boss Mode” plan costs $999 for six meetings booked per month or six hot leads per month — working out to approximately $165 per lead.

Unlike traditional agencies charging monthly retainers regardless of performance, you’re not paying for email volume, prospect list size, or setup fees. 

They don’t require three-month or six-month contracts — you renew only if satisfied with results. 

NerdyJoe offers a 30-day money-back guarantee. 

If they fail to deliver the promised number of leads, you receive a refund for missed target leads or the entire amount if they completely fail to meet goals.

Pros & cons of choosing NerdyJoe

Here are some advantages and disadvantages of choosing this cold email marketing agency:

ProsCons
Pay-per-result model charging only for delivered leads or meetingsFocus on quality over volume; not for businesses seeking bulk email
No long-term contracts; month-to-month flexibilityPricing generally requires consultation despite Boss Mode example
30-day money-back guarantee mitigating financial riskDeep personalization approach may limit campaign volume
Deep personalization using non-traditional data sourcesIndustry specialization means less relevant for non-tech businesses

What users say

While formalized platform ratings aren’t extensively available in public sources, NerdyJoe highlights specific client results achieved through their cold email strategy. 

They’ve secured multiple $24,000/year clients for content marketing agencies, generated over $ 300,000 in sales pipeline for one agency client, and achieved several guest blogging placements on prominent industry blogs, including Mailshake, CoSchedule, Hunter.io, and Appsumo.

The emphasis on results over vanity metrics resonates with clients tired of agencies reporting impressive open rates while delivering few actual leads. 

If you’re a tech or SaaS company willing to sacrifice volume for quality — and you want a risk-mitigated pricing model — NerdyJoe’s approach deserves serious consideration.

How to choose the best cold email marketing agency for your business

Picking the right cold email marketing agency isn’t about finding the “best” one. 

It’s about finding the best fit for your specific situation, budget, and goals. Here’s how to evaluate your options systematically.

Match your budget to realistic outcomes

Agencies range from $499/month (Agent Frank) to $10,000+ minimums (Belkins, Growth.cx). Be honest about what you can afford and sustain for at least three to six months. 

Cold email rarely produces instant results — you need runway to refine campaigns, test messaging, and build momentum. If $10,000 monthly feels uncomfortable, don’t stretch for premium agencies. 

Better to succeed with a mid-tier option than fail with a premium one because you couldn’t stick with it long enough.

Assess your internal capacity

Some agencies require significant collaboration (providing customer insights, reviewing copy, hopping on strategy calls), while others handle everything independently. 

If your team is stretched thin, full-service agencies like Belkins or SalesHive make sense despite higher costs. 

If you have marketing bandwidth and just need execution support, more affordable options like Agent Frank or NerdyJoe might suffice.

Prioritize specialized expertise

Generalist agencies work across industries, but specialists deliver better results in their niches. Growth.cx focuses exclusively on B2B SaaS and tech. 

Cleverly excels at LinkedIn-focused B2B outreach. NerdyJoe specializes in tech and SaaS. 

If your industry matches their focus, you’ll benefit from their accumulated knowledge about what messaging works, which objections prospects raise, and how to position against competitors.

Understand pricing model trade-offs

Pay-per-meeting models (Cleverly, NerdyJoe) align agency incentives with your success but may cost more per lead. 

Monthly retainers (SalesHive, Belkins) provide predictable costs but pay the same whether results exceed or miss targets. Performance-based models ((310) Creative) split the difference. 

Consider your risk tolerance and cash flow predictability when choosing.

Verify deliverability expertise

Agencies can write brilliant copy, but if emails land in spam folders, the results will disappoint. 

Ask potential agencies about their email warmup processes, DMARC setup practices, and how they handle email blacklist issues. 

Agencies that can’t speak intelligently about IP warming and SMTP servers likely lack the technical depth needed to maximize inbox placement.

Before signing contracts, run an email deliverability test on your current setup to establish a baseline — you’ll want to measure improvement after the agency starts working.

Demand transparency around metrics

Avoid agencies focused solely on vanity metrics like open rates or email volume sent. 

Those numbers look impressive in reports, but don’t pay your bills. Instead, focus on qualified meetings booked, qualified leads generated, and ideally, deals closed. 

Ask how they define “qualified” (their definition might differ drastically from yours), what CRM integrations they offer, and how they report results.

Maximize your deliverability rate before picking any agency

Agency success depends entirely on your emails actually reaching inboxes. 

The most brilliant copy, most thorough research, and most sophisticated AI personalization mean nothing if your messages land in spam folders.

Email Warmup

That’s where EmailWarmup.com comes in. 

We analyze your real campaigns and sequences, then replicate them so ESPs recognize you as legitimate (not the random garbage warmup that most tools send), offering: 

  • Personalized email warmup
  • Unlimited email deliverability test runs
  • Free email deliverability consultants assigned to your account
  • Our intelligent email spam checker shows real-time placement

Start with our Free Forever plan (one mailbox warmup, unlimited deliverability tests, free consultation).

Frequently asked questions

Here are some commonly asked questions about hiring cold email marketing agencies:

What’s the difference between a cold email agency and using email outreach platforms independently?

Email outreach platforms provide software and tools, but you handle strategy, copywriting, list building, and campaign management yourself. Agencies provide full-service execution — they build your lists, write your emails, handle deliverability, manage campaigns, and refine based on results. Agencies often have proprietary data from running thousands of campaigns that platforms can’t provide.

How long does it typically take to see results from a cold email agency?

Expect 30-60 days for meaningful results. The first two weeks typically focus on setup: building lists, warming up email accounts, writing initial copy, and configuring technical infrastructure. Weeks three through six involve sending campaigns, gathering data, and making initial refinements. Most agencies hit their stride around month two when they’ve accumulated enough data to identify best-performing segments and adjust send times.

Should I hire multiple cold email agencies simultaneously to increase lead volume?

This rarely works well. Running multiple agencies simultaneously creates fragmented messaging (prospects might receive different pitches from your company), deliverability risks (increased send volume triggers spam filters), duplicated targeting (agencies might contact the same prospects), and difficulty attributing results. Choose one agency and give it sufficient time and budget to deliver results.

What should I do if an agency delivers low-quality leads that don’t match my ideal customer profile?

Address this immediately. First, revisit your ICP documentation — often, “low quality” leads result from poorly defined targeting criteria during onboarding. Schedule a call to review who they’re targeting and provide specific examples of good-fit versus poor-fit leads. Second, request that they pause campaigns until alignment is achieved. Third, check your contract for quality guarantees or refund clauses.

How do I measure ROI from a cold email agency investment?

Track the full funnel, not just top-of-funnel metrics. Monitor qualified meetings booked, opportunities created in your CRM, deals closed, and revenue generated. Calculate cost per qualified meeting (agency fees divided by meetings booked) and compare that to your customer acquisition cost from other channels. Factor in customer attrition rates and lifetime customer value when evaluating ROI.

Can I use my existing email domain with an agency, or do I need to set up a new one?

Most agencies recommend setting up a secondary domain (like “yourbrand.io” if you own “yourbrand.com”) to protect your primary domain’s reputation. Cold outreach inevitably generates some spam complaints and bounces. If that happens on a secondary domain, your primary domain (used for customer communication and newsletters) remains protected.

What’s the difference between cold email agencies and traditional B2B email marketing companies?

B2B email marketing companies typically focus on nurturing existing leads through drip campaigns, newsletters, and automated sequences. They work with email lists of people who already know your brand. Cold email agencies specialize in outbound prospecting — reaching people who’ve never heard of you. Many companies need both: cold email agencies to fill the top of the funnel with new prospects, and marketing companies to nurture those prospects through the buying journey.
