We would rather you pick the right tool than the cheap one. Stay with MailSlurp if:
MailSlurp is a testing platform for developers: it gives you inboxes and an API to check that emails arrive and contain the right things, plus deliverability tests and metered device previews. EmailQA is a review tool: it renders your email in real Gmail, Outlook and Apple Mail clients and lets clients comment without an account while your team signs off. Many teams need one or the other; some use both.
MailSlurp includes 1 device render a month on its free plan, 5 on Starter ($19.99/month), 10 on Pro ($49.99/month) and 200 on Growth ($129.99/month), then $0.50 per render on Pro and Growth. EmailQA includes 25 renders a month free, 1,000 on Pro ($20/month) and 3,000 on Business ($99/month). The units may not match exactly: EmailQA counts one render per email client, with light and dark mode of the same client counted once.
Yes. A common split is MailSlurp for automated tests of transactional email and deliverability in CI, and EmailQA for design review, real-device rendering and client approval of marketing email.
MailSlurp is the better choice if: You test transactional flows (sign-up, password reset, one-time codes) with real inboxes in CI; Inbox placement and deliverability testing are part of your release checks; You need SMS testing alongside email; Yahoo or iPad Mail rendering matters to your audience; Your security review requires SSO, SCIM or SOC 2 from the vendor. For teams that mainly need rendering previews and stakeholder review, EmailQA covers that for $20/month flat.
