InboxDollars is a program I joined a few months ago.  It works in a very similar fashion in comparison to MyPoints.  Each day they will send you a couple emails for which you earn two to five cents for clicking and reading the email.  Almost all emails are advertisement in nature while some asks you to take surveys.  Some people calls the emails spam but in reality it is a pay to click skim.  The surveys are readily available but you must qualify for them.  Unlike the other survey sites, the payout is flat in nature and is usually 50 cent for each. In addition, they have additional offers such as Netflix trial in which you will get a portion of their affiliate earnings.

In conclusion, InboxDollars works in a very similar fashion to MyPoints.  It will not make you rich but it will definitely help for those people who are patient enough and looking for some side income here and there.
