Tip 7. Use Co-Registrations
Yes, if you’re really lazy, you can actually buy subscribers. Basically, it involves having your subscription offer listed alongside other publication's offers, so that when someone signs up to the other offers, they are given the option of signing up for yours as well.

But like I said before, there are better ‘free’ ways to increase your email list than this one so use it only as an additional method to the others.
