Advantage mailer features a simple on-click un-subscribe feature, allowing your members who do not want to continue to receive your email newsletters to stop receiving them. Each email that is sent out contains a special personalised link to allow members to unsubscribe.
Additionally, once a member unsubscribe's, their email address is blocked so that if their email address appears on more than 1 mailing list, they do not continue to receive your emails. You have full access to manage these blocked email addresses should your members want to start receiving your emails again.
Optionally, after a member has un subscribed, they have the option to complete a quick survey asking why they have chosen to unsubscribe. Regularly reviewing this data will help you tune your email newsletters to ensure the content is always relevant.
