Some features of InboxDollars are quite unique and not found on other paid-survey websites. Apart from the usual payment or survey taking, the website also enables members to read emails, sign up for corporate offers, watch videos, play games and generally surf the web in order to earn income. (For the record, InboxDollars isn't the only site that will pay you for playing games and surfing the web. Swagbucks is generally regarded as the best in the business when it comes to that kind of free money. Click here to read my honest review of Swagbucks)
When brands want to find out what consumers think about their product and services, they turn to market research companies. Market research companies are the ones actually administering the surveys on behalf of the corporations looking for data/feedback. Think of online surveys as a type of focus group, except in this case, everything is done online.
