If you are going to send email marketing campaigns, legally you need to provide a way for your subscribers to opt-out of your mailings if they want to.

little green plane puts an automatic unsubscribe button on the bottom of each of your emails to ensure you adhere to best-practice email marketing.

Each email you send through little green plane uses an unsubscribe mechanism that will automatically remove contacts from your mailing list.

Even if you accidently upload an unsubscribed contact to your list, you are safe in the knowledge that little green plane will not allow you to send an email to that recipient again, ensuring you are data protection compliant.
