We've created a mailer (In SFMC) which includes AMP script and is a trigger based mailer. Whenever a new lead is created a mailer should be triggered with recommended items. There is a separate data extension from which lookup is being applied for recommended items.
When I go to Test & Preview section of email, I'm not able to find this particular synchronised data extension on which mailer is being targeted.
- This synchronised data extension is not contacts. This data extension is child data extension of contact DE.
- Data integration has been done between sales cloud and marketing cloud.
