Testmail.app Pro is about $29/mo, and it's a solid API-first workhorse. If all you need is programmatic email assertions at the lowest price, buy Testmail. Reclario is $49/mo per domain, and the extra $20 covers things Testmail doesn't do: replying to calendar invites for you, a live inbox your whole team shares, and emails rendered the way real recipients see them.
Send a real ICS invite and the address tag decides the answer: accept, decline or propose a new time. Reclario can wait a few minutes first, like a person would, then emails the reply to the organizer. Testmail has no calendar features, and we haven't found another testing tool that does.
Testmail is API- and JSON-first, built for code to read. Reclario is a shared live inbox your whole team watches, with the same API access underneath.
Emails render in a sandbox the way recipients see them, and every message has its attachments and raw .eml ready to download. Reviewing HTML mail as JSON gets old fast.
Testmail organizes addresses as namespaces on shared infrastructure. Reclario gives your team a private catch-all domain of its own, and only members you invite can see the mail.
The address decides what happens. +accept, +decline, +maybe and +delay5 each script a different response, so every test case can have its own persona.
Your test automation can still provision addresses, read messages and get notified on delivery. Choosing the inbox doesn't mean giving up the API.
Testmail.app's free tier gives you 100 emails a month with 1-day retention. Starter is about $9/mo with 3-day retention. Pro is about $29/mo with unlimited emails, unlimited addresses via namespaces, custom domains, 30-day retention and unlimited users. Reclario is $49/mo per domain, or $490/yr (two months free), with unlimited addresses and inboxes and calendar auto-RSVP included. On raw price Testmail wins. The question is whether your team needs what the difference pays for.
Buy Testmail if you want the cheapest solid API-first email testing and don't need calendars or an inbox people read. Its namespaces, JSON API and $29 Pro tier with unlimited email make it a good deal when every assertion runs in CI. Pick Reclario when people need to read the mail too: watching a shared pipeline live, reviewing rendering and attachments, keeping candidate data on a private domain, or testing a scheduling flow where someone has to answer the invite.
Start a private catch-all domain at $49/mo per domain. If you’d like to look first, the public sandbox at public.reclar.io is free with a work email (no credit card).
