I imported a list of outdated email addresses and see that Constant Contact updated my contacts with the outdated email address. How to I undo or reverse this please? I need to get the email addresses from yesterday (before I uploaded the old addresses). Thanks!
There is no direct way to reverse the changes that were added to the contacts. We can try to provide you with the lists of contacts as they were before the changes. This will be a series of files, one for each existing list. You can then use these to update the contacts back to their original settings. These files will be emailed to the address we have on file for the account.
