About MailSlurp
What it does
MailSlurp is a programmable messaging platform that gives developers and QA engineers real email accounts and phone numbers for testing, automation, and delivery monitoring. It solves the problem of polluting real inboxes or missing edge cases in email-based user flows like signups, password resets, OTP/MFA, and notifications.
Who it is for
Best for developers, QA engineers, and teams building email-heavy applications. It is not a consumer email service (like Gmail) or a mass marketing tool β it is built for test automation, CI/CD pipelines, and inbound email processing.
Real use cases
Create disposable inboxes via API or dashboard, send and receive emails, verify delivery, and automate end-to-end testing with Playwright or Cypress. Also supports SMS testing, AI data extraction, and email delivery monitoring across providers like Outlook and Gmail.
