Today i have a question about list building.
Recently i could used a leverage way to increase the size of my list.
But the problem is when i got a lot of new subcribers, there are a half of that amount never opened
any email that i sent to them after 2 months.
For example: I got 3000 new fresh subcribers, but there are 1500 subcriber did not opened any emails from my after 2 months.
My question Is: Is that a nomal number? Or this is a not good result and i should somehow change it?
