A transactional email was sent to a large group but there was a list that needed to get excluded but it didn't get executed. The sendable DE has a contactid as a primary key and excluded DE had email id as a primary key, did that cause a problem? (both DEs have the email IDs). The location of the DEs are in different folders. That exclusion DE is created via a web form. (A few people opted out from getting a following email, they fill out their emails via a form which gets into a DE , which needs to be excluded). How to resolve this? @* Marketing Cloud Engagement *
Hi,@Nayra G
Primary key in both DEs should be the same field, and it should be used to uniquely identify contacts .
Data types for the email id(emailaddress) field in the exclusion DE and the contactid field in the sendable DE .
Primary key matches the subscriber key in the sendable DE.
Thanks,
