Hi @OntarioEquestrianF are you looking for all pervious subject lines to display on a single campaign’s detail page or just the subject line from that email? Also, what type of preview text would you like to see on this page?
IMO seeing the seeing the Open Rate and CTR alongside Subject line and preview text per campaign would be helpful in understanding potential success of past emails.
E.g. Something simple in the Email Stats Section as
Email Stats
Subject: This is the catchy Subject Line you Used!
Preview Text: This is what the user see's that enticed them to open the email!
