I often read that a subscriber worth $1 per month (for Internet marketers).
So, if you have 10000 subscribers on your list, you can expect to earn $10000, 15000 subscribers $15000...
Well, why not. But now I receive some emails from a marketer with a list over 50000. He offers some solos and give some proofs of the results he got with his big list. And the results are about $1000 per email send to his list. Only!
That's a big difference with what I read many times.
So, what is the average value for a subscriber in your opinion?
