Email on Acid Pricing [Does It Offer Value For Money?]

Email on Acid pricing starts at $74/month (billed annually), but you’ll probably need the $134/month Premium plan to get spam testing and full content checks. Is the pricing worth the money? (and what do you get for it?)

As an email marketing consultant who has helped hundreds of clients achieve the best ROI from their email programs, I’ve tested every tool worth testing. To help you out, I’ve prepped this guide on Email on Acid pricing, covering:

• How Email on Acid compares to competitors
• Whether the annual commitment pays off
• Complete pricing breakdown for all plans
• Features you actually get at each tier

Let’s find out if Email on Acid fits your budget (or if there’s a smarter choice).

What does Email on Acid pricing look like?

You’re looking at four tiers:

Professional tier pricing appears on third-party sites but isn’t currently shown on Email on Acid’s public pricing page.

How much does Email on Acid cost?

Email on Acid pushes annual billing because it saves you 25% compared to monthly payments. You’re locked in for a year, but the discount might make sense.

The Basics: $74/mo (annual) vs $99/mo (monthly)

The entry-level plan gives you the bare minimum:

• 1 user (add more for $30 each)
• Email editor with real-time HTML preview
• Unlimited email previews across 100+ clients
• Partial Campaign Precheck (not the full version)

Partial content checking means you’re flying blind on spam triggers before you hit send. You can test how emails look, but not whether they’ll land in the inbox (which is half the battle).

Premium: $134/mo (annual) vs $179/mo (monthly)

Premium adds what most teams can’t function without:

• 3 users (add more for $50 each)
• Comment and collaboration tools
• Spam testing across multiple filters
• Full Campaign Precheck with code validation
• Email analytics for 250,000 opens per month

Spam testing can save you from blacklist damage that tanks your sender reputation and costs thousands to fix. 

Another better alternative is this free email spam checker, which not only tells you if your email content is likely to trigger spam filters but also predicts (with accuracy) where the possible email is going to land, as well as where all your past emails have landed.

Professional: $424/mo (annual) vs $599/mo (monthly)

Built for agencies and high-volume senders (though this tier isn’t shown on Email on Acid’s public pricing page anymore and may require contacting sales):

• 10 users (add more for $50 each)
• Dedicated support representative
• 1.5 million analytics opens per month
• Custom user permissions and folder organization

Makes sense when you’re managing multiple clients or sending enough volume that 250K analytics opens won’t cut it.

Enterprise: Custom pricing

Requires a sales call — you get custom users, unlimited analytics, API access, and advanced permissions.

What features do you get with Email on Acid pricing?

Understanding what each tier includes helps you avoid paying for features you don’t need (or getting stuck without ones you do).

Unlimited previews (with coverage gaps)

Email on Acid’s biggest selling point is unlimited email previews. 

Most competitors (including Litmus at $500/month) cap your testing, creating bottlenecks when you’re iterating designs or running A/B tests.

But “unlimited” doesn’t mean “complete.” The platform has gaps, particularly with dark mode rendering on Gmail for Android and iOS. Some users report switching back to Litmus for this specific use case (despite paying more).

Campaign Precheck: Partial vs full

The Basics plan offers partial checks (accessibility, link validation, basic spelling) while Premium and Professional give you full checks (spam testing, code analysis, image optimization). 

That partial vs. full distinction matters more than Email on Acid’s marketing admits. Without spam testing, you’re guessing whether emails will land in the inbox or get flagged.

Analytics capacity jumps between tiers

Premium gives you 250,000 opens per month, while Professional bumps that to 1.5 million. 

If you’re tracking engagement on large campaigns, you’ll hit the Premium cap fast and get forced into Professional (whether you need 10 users or not).

How does Email on Acid pricing and features compare to those of its alternatives?

Email on Acid sits between budget tools and premium platforms:

Tool	Starting price	Unlimited previews	Spam testing	Best for
Email on Acid	$74/mo	Yes	Premium+ only	Teams needing unlimited testing without enterprise pricing
Litmus Core	$500/mo	No (2,000/mo)	Yes	Teams needing comprehensive dark mode coverage
Inbox Pirates	$4.99/mo	Yes	Yes	Budget-conscious teams with basic testing needs
Stripo	Free	Limited (70+ clients)	No	Designers needing an email builder with basic previews
Mailchimp	$13/mo	Limited	Basic checks	Small businesses already using Mailchimp for campaigns

Here’s how the main competitors stack up:

Litmus

Litmus offers better coverage when we conduct a full Litmus vs Email on Acid comparison. However, Litmus pricing is too high compared to any other alternative in the market.

You’re also capped at 2,000 previews monthly, which creates bottlenecks for agencies testing multiple client campaigns. The Core plan includes 5 users and 500,000 analytics opens.

Inbox Pirates

Inbox Pirates undercuts everyone at $4.99/month and includes spam testing even at the starter level.

You lose advanced features (white-labeled previews, detailed analytics), but if you’re running a one-person operation testing occasional campaigns, it’s hard to justify paying $74+ for Email on Acid.

Stripo

Stripo works as a free alternative for basic preview needs.

You receive over 70 client previews and an email design tool, but there’s no pre-deployment checklist or spam testing. It’s like a design tool with preview capability, not a comprehensive testing platform.

Others

Mailchimp and similar marketing platforms include basic email testing as part of their broader suite.

If you’re already paying for Mailchimp ($13/month and up), their built-in preview and spam checker might cover simple needs.

However, you won’t get the depth of testing that Email on Acid provides.

Are there hidden costs attached to the Email on Acid pricing?

Annual billing isn’t optional if you want reasonable rates. Monthly billing costs 25% more, turning that $74/mo into $99/mo ($300 extra annually just for billing flexibility).

Per-user costs scale by tier. The Basics plan charges $30 per additional user, while the Premium and Professional plans charge $50. Three extra users on Premium add $150/month.

The 7-day trial gives you 5 tests. Email on Acid’s documentation is unclear on whether a credit card is required upfront, so verify this during signup. You’re automatically charged if you don’t cancel.
