MailSlurp is a complete phone and email testing API for developers, QA engineers, and DevOps teams who need to automate, inspect, and control inbound and outbound communication in real time.

With MailSlurp, you can create real email addresses and phone numbers instantly via API or dashboard, send and receive messages programmatically, and integrate reliable end-to-end email workflows into your test, staging, or production environments. Utilize our temporary email API to improve developer velocity and application resilience.

- Email and Phone APIs: Create disposable inboxes and phone numbers on demand for automated testing or live applications using the disposable email API

- Inbound & Outbound Messaging: Send, receive, and parse emails and SMS messages with structured JSON or webhook callbacks. Use the SMS verification API to test OTP and MFA end to end.

- Attachments & HTML Parsing: Access message content, headers, and attachments for validation and compliance checks.
