I'd like some clarification on the dynamic sender profile AMPscript. When using this in the email:
%%[ VAR @fromName SET @fromName = Lookup("MySendProfilesDE","FROM_NAME", "SendProfileField", SENDABLE_DE_FIELD_TO_DRIVE_PROFILE) IF EMPTY (@fromName) THEN SET @fromName = 'MyDefaultFromName' ENDIF ]%% %%=v(@fromName)=%%
What does "SENDABLE_DE_FIELD_TO_DRIVE_PROFILE) mean? What should that be referencing?
