Firstly I realise there is going to be some big guess work going on here but I believe this forum is full of people who will be able to answer this far better than my guesses.
I own a website where I make free software to help their business growth online. I won't mention what its called because I don't want an insta-ban ha. But I've been working on it a while now and I'm enjoying it. I'm collecting around 40 emails a day (via people entering their emails to get the free software) and I haven't actually started promoting it yet really in any way.
So I'm hoping for around 200 emails a day pretty quickly. If I collect 200 emails a day how many months/years do you think it would take me (very approximately) to be able to live off this list (I'm UK based - lets say 20,000/$25,000).
If I have 70,000 emails after a year I'd like to think I could live off this list?
Am I being realistic here?
Any advice would be greatly appreciated :-)
