What is Mailtrap
Mailtrap provides email delivery infrastructure for transactional and marketing messages. Development and product teams use it to test, debug, and send emails with high inbox placement. The platform supports thousands of integrations and offers round-the-clock support.
Overview
Mailtrap is an email delivery and testing platform built for developers and product teams. It provides SMTP and API services for sending transactional and marketing emails while maintaining strong inbox placement rates. The platform includes an Email Sandbox that lets teams inspect and debug messages during development and staging without contacting real recipients. A shared dashboard displays delivery analytics and performance metrics. Setup takes minutes, which shortens development cycles and reduces email issues in production. The tool connects with over 5,000 applications through Zapier and supports frameworks like Heroku and Supabase.
How to use Mailtrap
Connect your application to Mailtrap using SMTP credentials or the REST API. Route staging traffic to the Email Sandbox to catch formatting and spam issues before they reach customers. Switch to the live sending mode for production transactional and marketing messages, then monitor delivery and engagement from the main dashboard.
