MyPoints isn’t as shady as them and isn’t as difficult. I’ve been clicking emails for 5-7 years (they offer surveys too but I only click emails) and cannot even remember how many gift cards I’ve gotten from them (a lot in that many years). Not once did they stop sending emails once I got to a certain amount of points. I can quit at any time after cashing out too, unlike InboxDollars who forces you to stay active until your payment is sent.
Surveys can be on many different topics, like your TV-watching habits, your favorite places to eat, what material of sweater you prefer in the fall, etc. Many surveys can take less than 5 minutes to complete, although some take longer (and pay more money). Despite the wide array of topics, the end goal of paid online surveys is usually the same: to get a better idea of what consumers are thinking and how they make decisions.
