How does the link work?
-----------------------

When the SMS recipient clicks on the link, they get redirected to an opt-out page.

Once the **Yes, unsubscribe** button is clicked, the contact is put on an SMS opt-out list on the level of the subaccount and is excluded from any future sending from that subaccount.

Note: the subscriber is not taken out of any contact list they were on.

What happens after a contact unsubscribes?
------------------------------------------

Every time an SMS is sent from that subaccount, numbers from the opt-out list are automatically excluded from the recipient list.

Opt-out stats are included in Sent SMS statistics.

Due to privacy protection laws, it’s not possible to check which numbers are on the opt-out list. We also don’t show how many contacts unsubscribed from each subaccount.

The opt-out list works also for SMS sent to numbers from a file.
