When a user unsubscribes from a type of email being sent to them MassMailer will suppress all of your attempts at sending this type of email to that user.
Suppression Management gives you the ability to create unsubscribe groups that represent types of email that you regularly send to your recipients.
For example, Newsletter, Product News, Marketing Communication, Donor Communication.
You can then give your recipients more control over the types of emails they want to receive by letting them opt out of messages from a certain group. This means getting the right messages to your recipient’s inbox, resulting in a stronger relationship with your recipients and a better sending reputation.
Make sure your group names and descriptions are customer-friendly! Your customers will see these group names and descriptions when they unsubscribe from your emails.
