If you use your email frequently, you might as well get paid for it! We Pay Mail is a PTR (paid-to-read) program that's been around for a couple of years. They pay up super-fast and have a low pay-out of $5.00.
We Pay Mail won't make you rich by any stretch of the imagination. However, if you're like me and could use some extra cash for things like gasoline or pet food, you should definitely look into it. At the very least, paid-to-read programs will add to your bottom line :)
