What happens when you click Unsubscribe in an email?

There are two ways you can unsubscribe from emails. Let’s understand the two kinds of Unsubscribe:

  1. You click on the client’s Unsubscribe link in the body of the email

    When you click on the Unsubscribe link in the body of an email (click here), the Subscriptions table is updated, and you are unsubscribed in that table from that specific email type/brand/domain. In this case, you will be available for all the future deliveries from the instance other than the type/brand/domain that you unsubscribed from. Please note this situation is not a bounce, it is a true Unsubscribe.

  2. You click on the Unsubscribe link in the email client itself

    A click on the Unsubscribe link in the email client itself (Gmail, Yahoo), will cause the Unsubscribed email to be sent back to the client’s instance (Campaign), and that email will be processed by InMail, and should match the Email_client_unsubscribe Inbound email rule. If it does, then the recipient will be shown as Quarantined in the Quarantine list, and will no longer be sent any emails, for any brand, from that instance. The Quarantine table will be then updated, and for that reason, in Campaign, this situation is considered as a Hard bounce. Although technically, this situation is not a bounce, it is considered as such since the Subscription table cannot be accessed in this situation. Therefore, Campaign cannot unsubscribe the recipient as requested. All InMail process can do is to update the Quarantine table.
