If 0 photos subject line:
Are potential customers seeing the best of %%Business_Name__c%%?
If > 1 photos subject line:
See who’s posting photos of %%Business_Name__c%% on XYZ
If no business name name subject line:
See who’s posting photos of your business on XYZ
Not sure the best way to solve this in AMPscript. My code:
%%[ IF (Number_of_Photos__c == 0 AND NOT EMPTY(Business_name__C)) THEN set @subjectline = Concat("Are Potential cusomters seeing the best of ",Business_name__c, "?") ELSE IF Business_name__C is not empty THEN set @subjectline = Concat("See whose posting photos of", Business_name__c," on XYZ") ELSE set @subjectline = See Who's posting photos of your business on XYZ ENDIF ]%%
