We tracked our junk/spam reports (which is reported back by all popular email services and software) and it was never terrible, but I don't have the numbers on a per email or campaign metric. As a whole we saw a 0.5% spam report rate. At its highest it hit 25% but that happened due to a glitch in the marketing platform that spammed every signup on one of our campaigns one night with around 100 "thank you" emails.
