So we experienced the elevated open & click rates from Hotmail / Microsoft email providers and had been fairly satisfied with the explanation that this was a “link testing” security feature. Unfortunately starting July 2nd our open rates from Hotmail plummeted:
Before these anomalies started our open rates for Hotmail hovered in the 30-40% range. Then they shot up to almost 100%, and now they’ve crashed to frequently below 20%. We haven’t changed anything about our targeting, email formatting, or anything else that would explain this —it seems entirely external.
Has anyone experienced anything similar (the drop in open rates I mean — I know plenty of people have seen the elevated click & open rates)
I emailed Klaviyo deliverability support but they just sent me the same canned replies about the elevated open rates.
Thanks!
Ben
