A couple people have requested to obtain stats on subject lines. Is there any kind of report that can be built in Marketo to generate a listing of subject lines that have been used for emails in programs?
No, this is not possible in the email performance report. You will have to use RCA to get this type or reports.
Your message says "see here" but there is no link. Can you please update?
name your programs the same as your winning subject lines for at least some level of reporting.
