I have an IP that I'm warming up, slowly getting traffic to it.
My question is what is a good open score to hold when you are warming up an IP?
I know that there are a lot of other stats to look for but I wonder what this can be.
Like, is it 15%, 20%, 30% and I'm talking about mostly value emails and a little bit of
promo emails like one every two weeks.
Let me know.
