If I export to Excel, I can change them to “Allow” and import the data BUT I cannot use the same downloaded file to then update that same list of contacts to set it back to “Do Not Allow” (because the system will recognise that the records have been updated since they were downloaded)
I could create another advanced find to give me all the contacts who have been modified by me on that date, but the contact entity records get updated so often by users and by flows, it would not be reliable.
I could go with the idea above of using a list of all contacts modified by me on that date and set those back to Do not Allow, then compare the list of contacts who have /Do not allow/ against my original downloaded list, do a VLOOKUP to find the ones that didn’t get reset and do those manually.
OR even better, is there any way to override that setting that prevents sending of bulk emails to contacts who have /Do Not Allow/ within a campaign? Then I wouldn’t have to do any updating.
