What is Mailrex?

Sending email is fraught with multiple challenges for developers.

Managing email templates, configuring mail servers, monitor and debug mail delivery up to mail open rate is a very time consuming and fiddly task. Mailrex solves all these problems. Through the simple UI, email html templates can be created and customized directly in the browser. Developers have the possibility to monitor the mail delivery and e.g. identify bounce mails and exclude them. Also the integration of pixels to monitor the email open rate is child's play with Mailrex.

And on top Mailrex ist free and open source.

Why we developed the software

The software was originally developed for the internal uniform management of all emails we send at KlexHub, to have a central point of contact for debugging, managing email templates and for statistical purposes. Especially when using micro services this can get confusing very fast.

We think the software can also solve problems of other developers / companies, so we decided to make mailrex open source.
