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)
How it works: Opinion Outpost sends survey opportunities to your email address at a fairly significant pace, but you won’t qualify for all of them — as with most other survey sites, you’ll have to answer a few pre-screening questions to make sure you fit the demographic profile the company is interested in learning about. You can also log on to the website and view available surveys without having to sift through emails.
My InboxDollars experience started on a high note. After receiving the signup bonus, I earned another 50 cents for completing a short profile survey. I also appreciated that I could see a list of surveys available to me, along with the exact dollar (or cent) amount they’re worth. Most sites we tested use points, and determining a survey’s monetary value can be a hassle. This list also included the estimated time required for each of the surveys and, for some, the topic.
