3608190 - SAP Marketing Cloud - Email Confirmations failing due to deprecated Sinch unsubscribe address

Confirmation emails are no longer send - the sending fails due to the following error:

• The deprecated Sinch unsubscribe address is used.

• SAP Marketing Cloud Edition

Option A:

1. Navigate to the Activate Confirmations app and check the logs of an active email or newsletter opt-in confirmation
2. Check the application log and find the following error:
   => The deprecated Sinch unsubscribe address is used

Option B:

1. Navigate to a confirmation email in the Content Studio app
2. Test send the confirmation email and receive the following error:
   => The deprecated Sinch unsubscribe address is used

The cause of the problem is a leftover of the Sinch endpoint switch:

• 3139747 - New Sinch service for email for SAP Marketing Cloud

It might happen that the confirmation email has still the old unsubscribe email address in use pointing to the @eu1mail.sapdigitalinterconnect.com domain.

First, please verify that the sender profile consumed by the confirmation mail uses the new @eusmtp.email.sdi.sinch.com domain. If confirmed please update the confirmation mail by removing and readding the sender profile again - this forces an update of the outdated unsubscribe email address as well.
