Learn moreInspect HTML, text, headers, links, and attachments

Use MailSlurp wait APIs and stored message artifacts so engineering, QA, and product can review the same output and fail builds on real regressions.
Learn moreStaging and pre-release notification review
Review signup, password reset, billing, and lifecycle email before it reaches real recipients. MailSlurp gives teams message evidence they can approve with confidence.
Safe local, QA, and CI email testing
Point apps and test environments at MailSlurp inboxes so developers and QA can exercise real send paths without leaking mail to customers, vendors, or internal groups.
Template and workflow regression checks
Catch broken copy, missing variables, wrong links, and attachment issues early by storing and inspecting the exact messages each workflow produced.
