Email testing, rendering and pre-deployment platform
Best for: Enterprise email teams needing pre-deployment QA across 70+ clients with accessibility and spam testing
Email preview & feedback tool
Best for: Teams focused on stakeholder feedback, approvals, and real-device rendering at a fraction of the cost
Email on Acid is a pre-deployment QA platform focused on rendering tests, accessibility checks, and spam scoring across 70+ clients. EmailQA covers real device rendering on the email clients that matter most — Gmail, Outlook, Apple Mail and more — in both Light Mode and Dark Mode, and adds the things Email on Acid charges extra for or lacks entirely: pin-based visual comments, guest-reviewer links with no account required, version comparison, and built-in approval workflows.

Yes — significantly. EmailQA gives you all Pro features free for 14 days, then $20/month flat. Email on Acid starts at $73/month on the Basic plan and most teams land on Premium at $134+/month once they need extra seats, projects, or integrations. Switching to EmailQA saves a small team $636/year on Basic or $1,368+/year on Premium.
Yes. EmailQA renders on real devices across the email clients that cover 95%+ of real subscriber inboxes: Gmail (Web, Android, iOS), Outlook (Windows, Mac, Web, iOS, Android), and Apple Mail (Mac and iOS) — with Light Mode and Dark Mode side-by-side. Email on Acid offers more niche clients (AOL, Outlook 2013, Lotus Notes) but most teams don't need them. If rendering plus feedback are your core needs, EmailQA covers both for a fraction of the cost.
For most teams, yes. EmailQA replaces Email on Acid's rendering, preview, multi-device testing, ESP imports, and approval workflow — and adds visual comments and guest review on top. The two things EmailQA does not replace are automated accessibility checking and spam-score testing; if those are critical for your compliance or deliverability process, some teams keep Email on Acid for those audits and use EmailQA for everything else.
No. Email on Acid has no free plan — they offer a 7-day trial, then pricing starts at $73/month on the Basic plan. EmailQA, by contrast, has a 14-day Pro trial with no credit card required, plus a permanently free plan with 3 projects per month after the trial ends.
Litmus has broader client coverage (90+ vs 70+) and stronger analytics; Email on Acid has tighter accessibility and pre-deployment QA. Both cost $73-$199+/month and neither has a free tier or pin-based collaborative review. For teams whose primary need is collaborative feedback and approval — not enterprise QA — EmailQA at $20/month replaces the rendering layer of either tool at a fraction of the cost.
