Disable signature deployment on Sellsy

To disable signature deployment on Sellsy, you must be an administrator of the Boost My Mail account and go to the Settings menu, then to the Synchronisation tab and the Sellsy section.

You can then untick the deployment activation. 

💡If you want to clean up the signatures, remember to manually delete any that may have remained in Sellsy. From the Email > Email settings > Email signature > Edit my signature section, you can delete the saved template.
