i want to import users from a csv file. Is it possible to import them without creating jommla useraccounts?
Yes, you can do that. Enjoy your Acymailing!
Great to know but how ☺ Is a german manual available?
Not to my knowledge. Go to Acymailing->Users and click on the import button. It's easy and it explains itself.
Here's the Enghlish documentation: https://docs.acymailing.com/main-pages/users/import
It is easy to export first a user file (don't forget to select the User Field on the left), then you have an example csv file.
