This function moves any archived customers back to active.

ie. those that have completed your autoresponder sequence will be placed back at the start of the sequence. When you reprocess your archived subscribers, the system will send them your first autoresponse message as it processes the email.

Note: This should only be used if follow-up messaging is enabled. If you have any invalid emails in your archive, you may get an error message - it is advisable to clean your list before processing.
