Question
Is there a way to resubscribe a large group that was unsubbed by mistake
We're using manual data input at the moment until our API is up and running and we mistakenly put 'True' in the Unsubscribed column of the input spreadsheet and have managed to manually unsubscribe about 1,100 contacts.
Is there a way undo this in one go rather than have to go into each entry individually and do it.
Thanks in advance.
