It's not all about your own records. Your contacts and customers took the time to take your survey, so it'd be nice for you to take a minute and say thank you. But it doesn't even have to take a minute of your time. All you need to do is have Zapier automatically send an email to each person who fills out your survey. You could even include extra info about your company, or perhaps a special coupon code as an extra thanks.
It’s easy to earn cash for surveys. How much you get paid completely depends on how many paid surveys you attempt and complete. Each online survey has a different payout, with some offering as much as $50. Most will pay less, but also take less time. Expect to earn about 40 to 200 SB points per survey (100 SB = $1), with occasional opportunities with much higher earning potential.
