According to Habeas Data law, when a user wants to revoke the authorization to receive communications, we must not keep user information in any Data Extension, so we need to look for a user record in all Data Extensions to delete all their information, is there any way to do this?
You can use contact deletion framework to remove a specific contact/subscriber key from all sendable data extensions. In order to do so (as per documentation):
- Navigate to All Contacts in Contact Builder.
- Select the checkbox next to the contact. Click the bin symbol, and select Delete selected contact.
Or alternatively- use the API route
You might need to enable contact deletion, if above step is not available.
Do also take a look on this Trailhead module about contact deletion.
It is also possible to automate contact deletion, if you need to do it on regular basis.
