Yes, thank you for explaining what I already understand. I understand your original point about Unique opens. It is s dead metric. This doesn't explain away total opens.

I have some automated responses, yes.

I'm obviously concerned or I wouldn't have asked the question. How do we explain unique opens vs total opens?

SO then my emails are most likely not landing? Muhammad S.?

Ok, that helps.

How is warming up different than just throttling my emails sends for 2 weeks? Like sending only a few per day?

Is warning them up for 14 days strictly necessary?
