I want to be able to report on metrics for the different subject lines used in nurture emails (in an engagement program) after carrying out A/B tests.
I can't figure out a good way to get A/B test reporting at all, without manually adding to a spreadsheet. I would love for someone to provide an answer to this!
What you can do is run an Email Performance Report and in the report's smart list, bring in the filter "Was Sent Email" and choose the email that was A/B tested. Now add a constraint to the filter for "Test Variant" and choose an option. You can load the report for this test variant and when you want to see the results for the other test variant, simply adjust the constraint option.
That is *very* manual though!
Very true. Unfortunately, as of now there is no way to report on these subject line variants separately but in the same view.
