Hi,
For some time now, we’ve had strong Open Rates for our broadcasts - in the early 70’s on average. However since Feb/March, they have dropped significantly down to the late 50’s.
Digging a little deeper, I can see that Gmail seems to be the culprit as the Open Rate for these subscribers was around 70% in January but is now just 45% :(
I’m quite concerned by this as Gmail subscribers make up around 60% of our base.
Does anyone know what could have caused this and how can I fix?
