I forgot that when you're running a campaign that each time you send the same email the results Marketo shows on the "email' tab are cumalative. Since I can't undo this, does anyone know if there's another way to see the open rates, CTR, etc by each run?
Were the runs on different days? If so, you can use an email performance report to break them out. You would just choose the send date in Setup.
If not, you could try using a smart list with a filter Was Sent Email > In Past 3 hours(or 4, 5, 6, hours, whatever works for your timing).
You could use that same filter and then at Opened Email, Was Delivered Email, etc, to get the rough open stats.
Does that makes sense?
Yes, you should use the Date of Activity filter in the Email Performance report AND/OR the Was Sent Email = X on Date = Y.
John is correct, I was just making it clearer.
