Add as many campaigns as you need, create expiry dates for each campaign, and leave a note or description to help you identify your campaigns.
Once you create your campaign… add your Mailer. It really is that simple!
Keep track of your campaigns through your campaign management system, add/edit your notes, and change which suppression list your email campaign Opt-Outs are assigned to.
Stay in the loop on the size of your suppression lists.
