APIs and Email Testing

Mailsac was built from the ground up with a rich REST API, pop3 access, and can even send you mail over web sockets.

Many large enterprises use Mailsac for automated testing. It scales and scales, can be used for load testing, and paid plans are not capped or metered like many competitors.
