How QAs use Email Sandbox

  • Check any emails within your end-to-end automated test suites

    Pick any, even the most complex email sequence and include it in the corresponding test.

  • Launch the tests

    Use Sandbox API to build and launch automated acceptance tests for the entire sequence.

  • Verify the test results automatically

    Confirm the results automatically using the Sandbox API. Validate if email headers and content are as expected and if the sending triggers work properly. Validate subject lines, links, attachments, and others.

After all these years of web development, how have I only JUST started using @Mailtrap. I had heard about it, but never got round to using it. An awesome way of testing emails.
