Built for developers


We build everything API first with a focus on simplicity and compliance to standards.

Send and receive email

Easy SMTP integration and a simple, RESTful API abstracts away the messy details of sending transactional or bulk email. Cut through the noise and clutter of inbound email with a solution that fits your use case with Mailgun’s Inbound Routes – our proprietary email parsing software. Improve your email conversion and open rate by automatically sending emails at the exact moment a recipient views their inbox with Send Time Optimization.
