Get paid reading emails (ad emails)

One possibility for making money online is to be paid to read emails. You won't make a lot but if you join many websites of this kind you stand a chance (like any other thing right?). Anyway, one of them that I like is sendearnings. One of the nice things about it is that you can make money also for participating in paid surveys or buying the stuff that you always buy. I like the fact that If i buy something through them i get the rewards that my credit card gives me and of course their rewards.
