Create group when importing a CSV file
If you import contacts in a CSV file, you can create a new group at the same time. To do this, simply enter a new group name in the corresponding field. Make sure that your new group does not already exist, otherwise the contacts will be added to this already existing group.
If you want to delete a group, click on the red trashcan symbol behind the respective group in the group overview. If you want to delete all contacts in the group as well, you have to confirm this in the screen that follows after you click the trashcan button.
