Is moving from testmail.app a big change?

The model is the same: build an address in code, send to it, read it back over HTTP. You change the address format and the read call.

Does Zyntra have live queries like testmail.app?

Not in the same form. /emails/last waits up to 30 seconds for the first email to an address. For a second email to the same address, your test asks again until the newest one is the one it expects.

Comparison

Zyntra vs testmail.app

Both give you addresses that need no setup and an API to read the mail, and paid plans cost the same. The difference is who reads the email: testmail.app goes further for pure CI (GraphQL, live queries, spam reports, many users), while Zyntra keeps mail longer and lets people and AI agents read it on every plan.
