About

It also offers a Verified Pro free plan with verification that includes unlimited private inboxes, 1 private domain, 10MB permanent storage, up to 10 emails per second, 2K emails per month, 60 emails per day, and 1 single user.

Free Tier Value
This free tier is genuinely usable: it includes unlimited public inboxes, API/webhooks, routing rules, SMS testing, and even load-testing tools, so it covers most of the core workflow-testing use case. The cheapest paid plan is Business at $79/month billed yearly, and the free offering keeps a large share of that practical capability while staying public and capped to temporary storage, so a fair monthly value is about $79. No credit card is needed for the public free plan, and the separate 14-day trial is not what drives this score.
