1. Introduction

OpenEMM is a professional open source software for email marketing and automation. If you want to automate your email communication, OpenEMM is the right choice for you. The software is not artificially limited in any way, because we will not try to push you to use a commercial cloud OpenEMM service instead. You are free to operate OpenEMM on whatever hardware you like, depending on the performance you need. And there is no need to use a (paid) email relay service!
The first version of OpenEMM was published in 2006. The source code of the frontend and the backend of OpenEMM 19.04 and later is available at GitHub. It uses the popular open source license AGLPv3. At the end of this page you can find instructions on how to build OpenEMM by yourself.

2. Basic Requirements

  • RedHat 7 to 9; AlmaLinux 8 or 9; SLES 15
  • Java Open JDK 11 or 17
  • Apache Tomcat 10.1 (including NIO Connector for HTTPS support)
  • Python 3.8 or later
  • DBMS: MariaDB 10.5 or 10.6
  • MTA: Postfix 2.6 or later

3. Mailing Templates and Forms

You do not have to start from scratch when producing mailings and creating forms in OpenEMM. At you can download templates and forms which you can import into OpenEMM. Make sure to replace all placeholders for a company ID with value “1”.

4. Updates

The top of this Wiki lists the latest available versions of OpenEMM backend, frontend and the deployment & runtime package.

You can download the latest versions of packages with menu “Install or update package from AGNITAS Website” of OMT (OpenEMM Maintenance Tool). An update of the code will also update the schema of the OpenEMM database, if necessary.

If you do not use the latest version of OpenEMM, OMT offers you to upgrade to a new release. If you are not happy with the new release (or any other version of OpenEMM), you can roll back OpenEMM to an earlier (or later) version with menu “Switch OpenEMM version”.

Do not forget to restart OpenEMM with menu “Restart OpenEMM” after you have downloaded and installed an update package to activate it. But do the restart at an convenient time: Do not restart OpenEMM during a dispatch of a mailing, or right after the dispatch (due to the brief downtime of the redirect service causing missed openings and click redirects).

5. Administration

See the Installation & Administration Guides linked at the top of this document for extensive information on administration of OpenEMM.
