OpenEMM 23.10: New version of the free software for email marketing and automation


OpenEMM 23.10Free software for email newsletters and transactional emails

Munich, January 17, 2024:


AGNITAS releases a new version of the open source software “OpenEMM” for the automation of e-mail communication in marketing, sales and administration. Version 23.10 has been enhanced with new functions for automated workflows and analysis and security functions, and its user-friendliness has been optimized. In the form of OpenEMM Plus, there are additional commercial extensions for even more use cases.


OpenEMM has been the software for individual and automated email communication at zero cost since 2006, because OpenEMM is permanently free of charge thanks to its open source license. GDPR compliance is also ensured by its own data protection functions. The semi-annual release cycle ensures that OpenEMM is always up to date with the latest technical and legal developments.

OpenEMM users are free to decide where and how they want to operate the software, giving them complete control over data protection and data security. Direct access to the source code allows security inspections and customizations. This makes OpenEMM an important building block for digital sovereignty.


The new OpenEMM: More functionality with improved usability

The highlights of the new version 23.10:

  • The Campaign Manager, a graphical no-code tool for designing automated workflows, has been significantly enhanced: optimized display, more execution options and new statistics.
  • The mailing evaluation has been expanded to include a table that lists data on bounces, deliveries, openings, clicks and unsubscribes for each recipient of a mailing. This table can also be exported.
  • There are now various new options for test mailings to test mailings with target group-dependent content even faster and more conveniently.
  • New functions have been added to the interfaces for SOAP web services and RESTful web services.

The management tool OMT (OpenEMM Maintenance Tool) has also been expanded and now offers additional status information, allows the setting of further configuration parameters and checks the checksums of the download packages. The OMT can also be used to exchange OpenEMM logos for white-label use, which facilitates commercial use by agencies and system houses.


Optional support assistance for open source customers

In addition to the free support forum, OpenEMM users can also take advantage of AGNITAS’ paid support services if they are unable or unwilling to provide the resources themselves. AGNITAS offers support in the following areas:

  • Installation, configuration and tuning
  • Consulting SPF, DKIM, DMARC and BIMI
  • Development of templates for mailings and forms
  • User training courses
  • Migration from OpenEMM to EMM Inhouse/SaaS


OpenEMM Plus with commercial extensions for even more use cases

With the new version OpenEMM 23.10, AGNITAS as developer of OpenEMM offers additional commercial modules for the first time, such as

  • the e-mail creator with layout builder and media pool for module-based mailing creation via drag & drop
  • an HTML interface for the automated filling of content modules in mailings (e.g. via CMS)
  • a module for automated data import and export for data exchange with external systems such as CRM, ERP, online stores, etc.
  • extended functionality for the SOAP and RESTful web services in order to be able to move large amounts of data and address the additional OpenEMM Plus functionality
  • a webhooks API to inform third-party systems about the reactions of e-mail recipients to the e-mails sent
  • an SMTP interface to receive and refine emails from legacy systems (display, bounce management, link tracking, etc.)
  • an extended client configuration for approx. 30 individual configurations for data protection, data security and other default settings

For OpenEMM users for whom the scope or performance of OpenEMM or OpenEMM Plus is not sufficient, AGNITAS offers a seamless upgrade to the license version of its big brother EMM (E-Marketing Manager), which is also multi-client and multi-server capable.


OpenEMM offers broad functionality for e-mail campaign management

OpenEMM is equally suitable for newsletters, multi-stage campaigns, transactional emails, service emails and autoresponders. An integrated WYSIWYG and HTML editor supports the design of mailings and forms. Numerous graphical and tabular statistics enable a detailed evaluation of success. GDPR compliance is ensured at all times.

With the help of the intuitive campaign manager, users can plan even complex email campaigns. For example, emails can be triggered by a deadline or a specific action, such as an online order, a subscription or a service request. Different execution paths can be defined for multi-stage campaigns, depending on reactions. A/B tests with automatic optimization can also be easily implemented with the Campaign Manager.

Interfaces such as the SOAP or RESTful API enable the OpenEMM to be connected to third-party systems such as CRM or online stores. As the source code is public, users can make changes and extensions to it as they wish.

With the OMT management tool, OpenEMM can be installed, configured, managed and updated on inexpensive Linux servers. Thanks to an OVA version, OpenEMM can also be installed under Windows or other operating systems via the open source virtualization VirtualBoxTM . A separate e-mail delivery service provider is not required, so that no additional costs are incurred for e-mail delivery.

To get the most out of the software, OpenEMM is extensively documented, from the installation instructions to the user manual and context-sensitive online help, both in German and English. In addition, numerous video tutorials support users with various tasks. OpenEMM users can also use the free support forum to exchange tricks and tips as well as problems.


Quote from Martin Aschoff, founder and CEO of AGNITAS AG:

“For anyone who wants to automate their email communication, OpenEMM is a building block for digital sovereignty. The software frees users from dependence on cloud operators with unclear locations and opaque security concepts. Users can decide for themselves where and how their data is stored.

On the one hand, this independence from third parties and the disclosure of the source code ensure maximum data security. On the other hand, they allow the software to be adapted and integrated for individual requirements.”
