I have this list that I have been building for 5 years now and it's getting big. And while I am making money with it, I feel like I am losing money by paying for the total amount of subs when many are not even active anymore.
I know some folks argue that some people won't buy until they are ready, so it's not a good idea to delete them. But at the same time, I am like how long are you going to keep an extra few thousands subs and pay for them in hopes of them someday reaching for their wallet.
So, after how many not opens or not clicked do you guys normally just delete them?...
Thanks in advance.
