Unlike some of the other sites, with Inbox Dollar, you essentially sign up to take advantage of whatever Inbox Dollar makes from their advertisers. They will send you emails which they get paid per receipt of you reading them or clicking a link. In turn, they give you a cut. Not to ruin your day but it's a rather small cut. The links that end up paying out the most usually have some stipulations attached – such as signing up for a service. This can end up being a lot more hassle than its worth and we recommend you pay VERY close attention to the stipulations.
