In their own words
testmail.app
testmail.app receives, parses, spam-tests, and indexes test emails for automated end-to-end testing. Messages sent to addresses such as `{namespace}.{tag}@inbox.testmail.app` are routed into mailboxes, allowing tests to create addresses and mailboxes dynamically. The service provides simple JSON and GraphQL APIs, with client examples for JavaScript, PHP, Ruby, Python, Go, Bash, C#, and Java. Search includes wildcard queries, live waits for new mail, sorting, pagination, attachments, and SpamAssassin reports. GraphQL adds advanced filters, field selection, and custom sorting unavailable in the simple JSON API. Documented integrations cover Cypress, Selenium, TestCafe, and email OTP testing. New accounts receive a 14-day trial without a credit card, then move to the free plan. Free includes 100 emails monthly and one-day retention. Paid plans start at $9/mo (annual). Hosting uses AWS, with encrypted data and passwordless logins.
