Click here to join SendEarnings. You get a $5 bonus to sign up, and you earn a little bit of money every time that you click to read e-mails from this company. I have earned about $12.50 so far, and the payout is $30, so I have a bit to go to get my check, but it's really easy to click through. You can also get more money from doing offers and surveys, but I don't really do them.

Does it not overwhelm your in or spam box??

I would say that I get about 5-10 e-mails per day, and I just click through to the site and just check to make sure that I don't have to click again to get credit. Then I delete the e-mail.
If you don't want those e-mails coming to your personal e-mail box, you could set up an e-mail just for this and/or freebie sign ups and check it a couple of times a week.
It's not for everyone, but I don't mind clicking through to make a little extra money.
