Thanks for moving the thread and sorry for the delay.
Can't say I've seen anything appreciable, but what's "a ton" both in absolute terms and percentage-wise?
An increase in logged open rate could be due to 3 very different factors:
Ive notice regular opens nearer to 50% recently. I'm suspicious but we have just moved to a dedicated IP and our lists are strictly cleaned. However Id prefer an increase in CTO.
I really need some way to eliminate the mail scanner activities. Open rates at the moment feel meaningless.
