    Significant Drop in Open Rates for Trial Nurture

    Jessica Biblis

      In November 2016, we launched a new trial nurture and we've had really great engagement with it up until about 3 weeks ago, when our open rates dropped by nearly half. We haven't made any changes to the email content or to how the emails are being sent, the cadence and frequency.


      I've submitted the emails to mail-tester.com and all have a passing score. I've checked our domain across multiple blacklist checkers, and we're all clear there. I've even reached out to support for guidance, but was given a rather generic response instead of some real help.


      I check our domain's Sender Score from Return Path and while the majority of the sending IPs are in the 80-90s, there are some that are not so hot. How can I improve the sender scores for these poor performing IPs? Is there any way to control that if we don't have a dedicated IP with Marketo?


      Any other advice for troubleshooting what could be causing such a significant drop?
