Different Font in emails

  • Used Zammad version: 6.4.1
  • Used Zammad installation type: (source, package, docker-compose, …)
  • Operating system: Windows 11
  • Browser + version: Microsoft Edge 131.0.2903.86

Expected behavior:

  • Before the update to 6.4.1, the emails created by Zammad (notifications and notes) had the font Calibri with size 11.

Actual behavior:

  • After the update to 4.6.1, the font is Helvetica with size 9.

In the html view of the emails, Helvetica with size 12 is displayed in both emails (before and after the update).

Did the font and size change with the update and how can we change back to Calibri size 11?

Steps to reproduce the behavior:

  • Update from version 6.3 to 6.4.1

This is a client, not a Zammad problem.
