For recurring campaigns in which the contact list does not change, but the contacts within the contact list changes, it would be helpful to be able to delete all (or selected) contacts from a list at the same time.
(To my knowledge) Currently when Viewing Contacts of a list, only single-delete is possible (see attached).
Two possible solutions would be
a) create check box per row within "Total Contacts" overview with possibility to select all + add a Delete button (e,g, next to export/import icons)
b) (only for deleting all, adjustments to contact list can be made through new import) When selecting Action dots of a contact list, add "Delete All Contacts" under "Export List" and "Import List" or under "View Contacts"
