Zammad facilitates communication and has thus proven itself in many industries, for example, IT support, services/retail and public institutions. The system connects numerous channels (such as phone, email, contact form or social media) and turns incoming messages into tickets. This way, you have everything in one place and can assign it directly to the right colleagues.

Zammad has many features that support you and increase your team's productivity, such as text modules, ticket templates and various automations. The various integrations allow you to connect third-party systems and exchange data and information between your tools. Thanks to the individual overviews and helpful reporting, you can keep an eye on everything.

You can get the community version from Univention. With this version, you can use Zammad freely and turn to the community for support. An additional support contract assures you the support of the Zammad team, if something hangs, and always ensures quick help.

Here's what you can look forward to:

  • Individual and clear interfaces for structuring your own requests / tasks
  • Customizable automations
  • Connectivity miracle for connecting any communication channel
