We have set up our Sales Cloud - Marketing Cloud integration where Contact ID is used as the subscriber key. What we've noticed is when we have contact ID as the subscriber relationship on our sendable data extension, Marketing Cloud will reference contact ID on All Subscribers list and if data matches, it will send to the email address listed on All Subscribers and not to the one on the data extension. This has caused us headaches for a number of reasons:
- Email addresses always change so the one on All Subscribers is out-of-date.
- Whilst preference center can update a recipients address and write this back to All Subscribers that not how most addresses are updated by the user
- Email address is typically updated in Sales Cloud instance and migrated to Marketing Cloud either through imports or via synchronized data extensions. It does not map directly to All Subscribers.
- Marketing Cloud users assume (and quite rightly) the address listed on the data extension is what will be used in the send. Not the one on All subscribers.
Anyone else experienced this? Any solution to resolve this issue?
