Both Klaviyo and HubSpot promise to transform your email marketing, but they take completely different approaches. One specializes in e-commerce precision, the other offers comprehensive business growth tools.
As an email deliverability consultant and marketer who has helped hundreds of DTC brands maintain 95%+ inbox rates during platform migrations and scaling phases, I’ve prepared this comprehensive Klaviyo vs HubSpot comparison guide that covers:
- Complete feature comparison between the two
- Pros and cons based on actual client experiences
- Decision framework for your specific business model
- Real-world pricing analysis with hidden costs revealed
- Migration strategies that protect your sender reputation
Let’s help you figure out which platform fits your business and how to implement it without risking your email deliverability.
Klaviyo vs HubSpot — Which platform should you choose? (Quick answer)
Sometimes you just need the bottom line without wading through thousands of words.
| Your Business Type | Choose This | Why |
| E-commerce/DTC brand | Klaviyo | Built for online stores, better product flows, stronger revenue tracking |
| B2B with long sales cycles | HubSpot | Comprehensive CRM, lead nurturing, sales team tools |
| Service-based business | HubSpot | Client management, proposal tracking, multi-channel marketing |
| Shopify-focused store | Klaviyo | Native integration depth, automatic product data sync |
| Multi-department team | HubSpot | Marketing, sales, service coordination in one platform |
| Email marketing focused | Klaviyo | Specialized automation, better templates, SMS included |
| Need landing pages | HubSpot | Built-in page builder (Klaviyo doesn’t offer this) |
| Tight budget | Klaviyo | More affordable scaling, transparent pricing |
| Enterprise requirements | HubSpot | Advanced permissions, unlimited users, complex reporting |
Klaviyo starts cheaper but scales with contacts. HubSpot jumps to $890/month for advanced features (plus $3,000 onboarding) —- both offer solid free plans for testing.
Either direction takes 4-8 weeks. Protect your email reputation with proper warmup during transitions (that’s where we come in).

Which business model works better with Klaviyo or HubSpot?
Your business model determines everything. Get this wrong, and you’ll spend months fighting against your platform instead of growing with it.
Klaviyo overview
Klaviyo built its reputation as the e-commerce specialist. Founded in 2012, it focuses primarily on helping online retailers convert customer data into revenue through hyper-personalized email and SMS campaigns. However, the platform has recently expanded beyond email-only functionality, adding WhatsApp/RCS messaging and B2C CRM analytics modules.
HubSpot overview
HubSpot takes the opposite approach. Since 2006, it’s evolved into a comprehensive inbound marketing and CRM ecosystem. The platform champions integrated business growth, connecting marketing, sales, and customer service into one unified system.
How do Klaviyo and HubSpot compare across core features?
Both platforms excel in different areas, but the devil lives in the details.
Email marketing and automation capabilities
Here’s how both stack up in this domain:
| Feature | Klaviyo | HubSpot |
| Omnichannel automation on the free plan | Yes (email + SMS) | No (requires Pro plan) |
| E-commerce specific flows | Pre-built, data-driven | Manual setup required |
| CRM workflow integration | Limited | Comprehensive |
| Advanced multi-channel features | Email/SMS focus | Email, social, ads, landing pages |
Klaviyo’s automation flows feel like they were designed by someone who actually ran an online store. The pre-built sequences for abandoned carts, browse abandonment, and post-purchase follow-ups work immediately without extensive customization.
I recently helped a client migrate from HubSpot to Klaviyo, and their abandoned cart recovery rate jumped from 12% to 28% within the first month. The difference? Klaviyo’s flows automatically pulled live product data, pricing, and inventory status into each email (something that required manual setup in HubSpot).
Moreover, Klaviyo offers omnichannel email and SMS automation even on the free plan. The platform can optimize send times using account-level data through its Smart Send Time feature, analyzing your brand’s historical performance to identify optimal timing windows.
HubSpot’s automation strength lies in its breadth. The workflow builder handles complex, multi-channel sequences that combine sales actions, website behavior, and customer service interactions. You can create sophisticated lead nurturing campaigns that automatically assign sales reps, update CRM records, and trigger service tickets based on customer actions.
However, HubSpot’s automation can initially feel overwhelming. One client described it as “having a Ferrari when you just need to drive to the grocery store” (they switched to Klaviyo after six months of struggling with setup complexity).
Template design and user experience
Klaviyo wins the visual appeal contest hands down. Their extensive template library looks modern and converts well for e-commerce. I consistently see higher engagement rates when clients use Klaviyo’s product-focused designs compared to generic business templates.
Furthermore, the drag-and-drop editor includes e-commerce elements like product blocks, recommendation feeds, and dynamic pricing that pull real-time data from your store. You can create emails that automatically showcase products based on browsing history without touching a line of code.
HubSpot’s templates lean toward professional and corporate. They work well for B2B communications and nurture sequences, but feel dated for retail brands. The platform offers several hundred templates, but many clients describe them as “plain-looking” compared to Klaviyo’s retail-focused designs.
That said, HubSpot’s landing page builder outperforms Klaviyo significantly. If you need integrated landing pages, forms, and website functionality, HubSpot provides a complete solution that Klaviyo simply doesn’t offer natively.
Customer data and CRM functionality
This comparison reveals the fundamental difference between these platforms.
HubSpot operates as a proper CRM with robust contact management, deal tracking, sales pipeline visualization, and customer service integration. You get a complete view of customer interactions across marketing, sales, and support touchpoints. The free CRM alone offers more functionality than many paid alternatives.
Additionally, HubSpot’s workflow automation can update contact properties, assign owners, enroll contacts in sequences, create support tickets, and coordinate actions across multiple departments.
Klaviyo approaches customer data differently. It’s designed as an e-commerce marketing database that captures purchase history, browsing behavior, and predicted customer lifetime value. The segmentation capabilities are incredibly granular (you can create segments like “VIP customers who abandoned carts containing products over $200 in the last 30 days”).
One e-commerce client told me, “Klaviyo knows my customers better than I do.” The platform’s predictive analytics forecast when customers are likely to purchase again, their lifetime value, and churn risk.
Nevertheless, Klaviyo lacks traditional CRM features. You won’t find deal pipelines, task management, or phone calling systems. If your business relies on sales team collaboration, HubSpot’s CRM integration provides essential functionality that Klaviyo cannot match.
What’s the real cost difference between Klaviyo and HubSpot?
Pricing complexity often surprises businesses more than the actual costs. Both platforms use different models that can significantly impact your budget as you scale.
Free plan limitations
Klaviyo’s free plan supports 250 active profiles and 500 monthly emails, plus 150 SMS credits (availability varies by country and number type). You get access to nearly all features, including segmentation, automation flows, and the complete template library. It’s genuinely useful for small businesses starting their email marketing journey.
Also, free users receive email support for the first 60 days, then rely on community forums and documentation for assistance.
HubSpot’s free CRM includes 2,000 monthly emails and basic marketing tools. While the email volume is higher, many advanced features require paid upgrades. The free tier works well for basic customer management but lacks the automation depth most growing businesses need.
Paid plan reality check
Klaviyo’s pricing scales with your contact list size. For example, expect to pay around $20/month for 500 contacts, approximately $150/month for 10,000 contacts, or roughly $1,200/month for 100,000 contacts. SMS adds usage-based costs, but the pricing remains predictable and transparent.
HubSpot’s tiered structure creates pricing jumps that can shock unprepared buyers:
| Plan | Monthly Cost | Marketing Contacts | Key Features |
| Starter | $20 | 1,000 | Limited automation, basic tools |
| Professional | $890 | 2,000 | Advanced automation, phone support |
| Enterprise | $3,600 | 10,000 | Full feature access, custom reporting |
One client’s HubSpot Professional plan costs $1,200/month after adding necessary features and additional marketing contacts. They switched to Klaviyo’s equivalent functionality for $180/month (though they lost CRM integration and landing page capabilities). However, HubSpot costs vary significantly by marketing contacts, seats, and add-ons, so readers should expect variability.
Hidden costs that add up
Both platforms include usage limits that can surprise you during growth phases.
Klaviyo considerations:
- Advanced customization may require HTML knowledge or developer time
- SMS costs scale quickly with volume (though pricing remains transparent)
- Integration setup might need technical expertise for complex e-commerce stacks
HubSpot surprises:
- Advanced features are often locked behind higher pricing tiers
- Additional costs for extra marketing contacts beyond plan limits
- Mandatory onboarding fees for Professional plans (typically $3,000)
- Multiple “Hubs” (Marketing, Sales, Service) require separate subscriptions for full functionality
How do Klaviyo and HubSpot handle integrations differently?
Integration capabilities determine how well your chosen platform fits into your existing business operations. Both approaches have distinct advantages depending on your technology stack.
E-commerce platform connections
Klaviyo built its reputation on deep e-commerce integrations. The connections with Shopify, WooCommerce, Magento, and BigCommerce sync real-time customer data, order history, and product information automatically. You can trigger emails based on specific product views, cart additions, or purchase behaviors without manual setup.
I helped one Shopify Plus client implement Klaviyo’s integration, and within 24 hours, their automated flows were pulling live inventory data, personalized product recommendations, and dynamic pricing into every email. The setup required minimal technical knowledge.
HubSpot offers over 1,700+ integrations across various business categories, but the e-commerce connections lack the depth that Klaviyo provides. While you can connect HubSpot to e-commerce platforms, achieving the same level of behavioral targeting often requires additional configuration or third-party tools.
Third-party ecosystem breadth
HubSpot’s integration marketplace covers virtually every business function: CRM connectors, project management tools, accounting software, communication platforms, and analytics solutions. If you’re building a comprehensive business technology stack, HubSpot likely connects to everything you need.
Furthermore, the platform’s API documentation supports the automation of complex business processes across multiple departments.
Klaviyo focuses on 350+ specialized integrations that support e-commerce marketing. You’ll find connections to review platforms (Yotpo, Trustpilot), subscription management (ReCharge), customer service tools (Gorgias), and advertising platforms (Facebook Custom Audiences).
Custom integration flexibility
Both platforms offer robust APIs for custom integrations, but they serve different use cases. HubSpot’s API documentation supports complex business process automation across multiple departments. Klaviyo’s API excels at custom e-commerce event tracking and behavioral data collection.
One technology client needed to sync proprietary customer data with their email platform. HubSpot’s API handled the integration smoothly, but Klaviyo’s e-commerce-focused structure made the same data more actionable for marketing campaigns.
Note that Klaviyo and HubSpot don’t integrate natively. However, you can connect them using third-party tools like Zapier, Outfunnel, or Make to sync contact data and campaign events between platforms.
Which platform offers better support: Klaviyo or HubSpot?
Support quality can make or break your platform experience, especially during critical campaign launches or technical issues. Both platforms take different approaches to customer assistance.
Response times and availability
HubSpot Professional and Enterprise plans include phone support, while Starter plans get chat and email support. The response times are generally quick, and the support team handles questions across marketing, sales, and service functions.
However, initial responses sometimes feel scripted or redirect you to documentation. Complex issues typically get escalated to specialists, which can extend resolution time.
Klaviyo offers 24/7 email support for paid plans, with live chat availability varying by location and plan tier. While not available around the clock for all features, the support team specializes in e-commerce marketing and understands the nuances of online retail campaigns.
Educational resources and training
HubSpot Academy stands out as one of the most comprehensive learning platforms in the marketing technology space. The free courses cover inbound marketing, email marketing, sales processes, and platform-specific training with industry-recognized certifications.
Additionally, HubSpot provides consulting-based onboarding processes where experts offer one-on-one training to help users learn the platform effectively.
Klaviyo Academy focuses specifically on e-commerce email marketing with courses on segmentation, automation flows, and deliverability. While narrower in scope, the content directly applies to online retail scenarios.
One client noted:
“HubSpot Academy taught me marketing theory, but Klaviyo’s resources showed me exactly how to increase my store’s revenue.”
Community and peer support
HubSpot maintains active user groups, community forums, and hosts the annual INBOUND conference. The community covers diverse industries and business models, providing broad networking opportunities.
Klaviyo’s community focuses on e-commerce marketers sharing tactics, campaign strategies, and platform tips. While smaller than HubSpot’s community, the discussions directly address the challenges online retailers face.
When should you choose Klaviyo over HubSpot?
Klaviyo makes sense when e-commerce revenue drives your business and email marketing is your primary growth channel. The platform’s specialization provides immediate value for specific business scenarios.
Ideal business scenarios for Klaviyo
Here are different scenarios to explore:
Direct-to-consumer brands
If you sell physical or digital products directly to consumers, Klaviyo’s e-commerce specialization provides immediate value. The platform understands customer purchase patterns, seasonal trends, and lifecycle marketing better than general-purpose alternatives.
High email marketing dependence
When email generates 25-40% of your total revenue, Klaviyo’s advanced segmentation and predictive analytics justify the investment. The platform’s ability to forecast customer lifetime value and churn risk enables sophisticated retention strategies.
Shopify-centric operations
Businesses built on Shopify or Shopify Plus benefit from Klaviyo’s native integration depth. The real-time data sync and automated product recommendations work seamlessly without technical configuration.
Limited technical resources
Small teams appreciate Klaviyo’s intuitive interface and pre-built e-commerce flows. You can launch sophisticated automation sequences without extensive technical knowledge or developer support.
Team size and growth stage considerations
Klaviyo works well for lean teams (3-8 marketers) focused on email and SMS marketing. The platform’s specialization means faster implementation and quicker results for e-commerce scenarios.
Moreover, growing businesses ($5-25M ARR) often find that Klaviyo provides the perfect balance of advanced features and manageable complexity. You can implement advanced segmentation and predictive analytics without enterprise-level complexity.
However, Klaviyo becomes limiting as teams grow and diversify their marketing efforts. If you need integrated content marketing, social media management, or complex sales processes, the platform’s focus becomes a constraint.
When does HubSpot make more sense than Klaviyo?
HubSpot’s comprehensive approach serves businesses with complex customer journeys and integrated sales processes. The platform excels in specific business scenarios where breadth matters more than depth.
Business models that favor HubSpot
Here are different scenarios to explore:
B2B companies with long sales cycles
When prospects require multiple touchpoints, educational content, and sales team interaction before purchasing, HubSpot’s integrated CRM and marketing automation excel. The platform tracks prospect behavior across multiple channels and coordinates marketing and sales efforts.
Service-based businesses
Professional services, agencies, and consulting firms benefit from HubSpot’s lead management, proposal tracking, and client communication tools. The platform connects marketing campaigns directly to business development activities.
Multi-channel marketing requirements
Businesses that need integrated content marketing, social media management, SEO tools, and advertising management find HubSpot’s unified platform advantageous. Instead of managing multiple tools, you coordinate all marketing activities from one dashboard.
Complex organizational structures
Larger teams with dedicated marketing, sales, and customer service departments benefit from HubSpot’s cross-functional collaboration features. The platform ensures all departments have access to consistent customer data and communication history.
Enterprise and scaling considerations
HubSpot handles enterprise requirements better than Klaviyo. The platform supports unlimited users, advanced permissions, and sophisticated reporting across multiple business functions.
Furthermore, companies planning aggressive growth appreciate HubSpot’s ability to scale from startup to enterprise without platform changes. You can start with basic CRM functionality and gradually add marketing, sales, and service capabilities as your business grows.
However, this flexibility comes with complexity. Multiple clients have noted that HubSpot’s extensive feature set can overwhelm small teams and delay implementation timelines.
What about deliverability — Klaviyo vs HubSpot performance?
Email deliverability determines whether your carefully crafted campaigns actually reach customers. Inbox placement depends far more on your sending practices than your platform choice.
Infrastructure and authentication standards
Both Klaviyo and HubSpot provide solid technical infrastructure for email delivery. Klaviyo automatically handles DKIM and SPF authentication while requiring users to verify their sending domains. The platform’s email infrastructure suppresses hard bounces automatically and maintains relationships with major ISPs through feedback loops.
HubSpot uses its own email-sending infrastructure with thorough domain authentication requirements. The platform’s comprehensive compliance framework and security monitoring provide enterprise-level deliverability protection.
Independent tests (such as EmailTooltester) have shown wide variance across brands and testing periods, and some providers aren’t included in every study. The foundation of good deliverability starts with your practices, not your platform choice.
Monitoring and optimization tools
Klaviyo provides real-time deliverability reporting with domain-specific performance metrics. You can track bounce rates, spam complaints, and engagement metrics with industry benchmark comparisons. The dedicated deliverability dashboard includes a sender score that helps identify potential issues.
HubSpot offers similar monitoring capabilities with additional insights into multi-touch attribution and cross-channel performance. The platform’s analytics integrate email deliverability with broader marketing metrics, providing context for campaign performance.
If you are still unsure where your emails are landing and how good your deliverability rate is, you can use a free email spam checker extension that doesn’t just tell you what percentage of your future emails are going to spam or inbox, but also tells you exactly where your sent emails went.
Dedicated IP and advanced features
Both Klaviyo and HubSpot offer dedicated IPs as add-ons for qualifying high-volume senders (not included by default). Dedicated IP access typically requires consistent sending volumes to maintain reputation scores.
Use platform-agnostic practices for optimal deliverability:
- List hygiene
- Relevant content
- Gradual warmups
- Authentication setup
- Monitor domain-level and Mailbox-provider-level metrics in your ESP

How do you migrate between Klaviyo and HubSpot safely?
Platform migrations risk damaging your sender reputation and losing valuable customer data. Proper planning protects your deliverability during transition periods and ensures business continuity.
Data transfer considerations
Moving from HubSpot to Klaviyo requires careful contact segmentation and engagement history preservation. Klaviyo’s e-commerce focus means some HubSpot data (like sales pipeline information) won’t transfer directly, but customer purchase history and engagement data migrate effectively.
Klaviyo to HubSpot migrations involve expanding your data model to accommodate CRM functionality. You’ll gain comprehensive business tracking but may lose some e-commerce-specific automation triggers that don’t translate to HubSpot’s broader framework.
Therefore, I recommend conducting migrations in phases rather than switching everything simultaneously. Start with a subset of your most engaged subscribers, monitor deliverability metrics closely, and gradually migrate additional segments based on performance.
Deliverability protection strategies
Platform switches often trigger ISP scrutiny because sending patterns change suddenly. Your new platform uses different IP addresses and may have different authentication protocols, which can temporarily impact inbox placement rates.
Warm up your sending reputation gradually on the new platform while maintaining reduced activity on your current system. This parallel approach lets you test deliverability without risking your entire email program.
Also, list validation becomes critical during migrations. Use the transition period to remove inactive subscribers, update suppression lists, and verify contact information. Clean lists improve deliverability faster on any new platform. You can use an email validation API to assist you.
Timeline and resource planning
Most migrations require 4-8 weeks, depending on complexity and business size. E-commerce businesses moving to Klaviyo typically complete migrations faster due to the platform’s streamlined setup process.
HubSpot migrations often take longer due to the platform’s comprehensive feature set and the required onboarding processes. Budget additional time for team training and workflow optimization.
Technical resources vary by migration direction. Klaviyo’s simplicity means that less technical support is required, while HubSpot’s complexity may necessitate the involvement of dedicated implementation specialists or agency partners.
Keep your emails reaching inboxes during your Klaviyo vs HubSpot journey
Platform choice matters, but deliverability protection matters more. I’ve watched too many businesses lose months of progress because they focused on features without protecting their fundamental ability to reach customers.
Whether you choose Klaviyo’s e-commerce precision or HubSpot’s comprehensive growth platform, your success depends on maintaining trust with inbox providers throughout your journey.
Maxify Inbox by EmailWarmup ensures your emails reach prospects regardless of platform transitions:

Frequently Asked Questions
Here are commonly asked questions on this topic:
Yes, though they don’t integrate natively. Many businesses use third-party tools like Zapier, Make, or Outfunnel to sync contact data and campaign events between platforms. This setup typically involves HubSpot handling top-of-funnel lead generation and CRM functions while Klaviyo manages e-commerce email marketing and customer retention flows. Expect additional complexity and potential data sync delays with this approach.
Deliverability depends more on your sender reputation, list quality, and content practices than platform choice. Both Klaviyo and HubSpot provide solid technical infrastructure, but platform-reported delivery rates reflect their user bases rather than platform capabilities. Focus on list hygiene, engagement quality, and proper authentication regardless of platform choice.
Plan 4-8 weeks for complete migrations, depending on your business complexity. Simple e-commerce moves to Klaviyo often complete faster, while comprehensive HubSpot implementations require additional time for CRM setup and team training. The technical migration itself takes days, but testing, optimization, and team adaptation extend the timeline significantly.
Platform changes can temporarily impact deliverability because you’re using new IP addresses and potentially different authentication protocols. ISPs notice sudden changes in sending patterns and may increase scrutiny initially. Proper warmup procedures, gradual volume increases, and maintaining list quality minimize reputation risks during transitions.
Klaviyo requires minimal technical knowledge for basic e-commerce setup, though advanced customizations benefit from HTML and CSS skills. HubSpot’s broader feature set creates a steeper learning curve, but the platform provides extensive documentation and guided onboarding. Most businesses succeed with either platform, utilizing existing marketing team skills, although complex integrations may require developer support.
ROI depends on how well platform capabilities align with your business model and growth stage. E-commerce businesses typically see faster ROI with Klaviyo due to its specialized automation flows and revenue attribution features. HubSpot may provide better long-term ROI for businesses needing comprehensive CRM functionality and multi-channel marketing coordination, but the initial investment and complexity are significantly higher.
