My 1st (and only so far) survey came on March 25th. I was asked to rate print ads for MR Visa.
This was part of the email:
In this next survey we are looking for feedback on some ads for the Marriott Rewards Visa program. Participation should only take 5 to 10 minutes of your time.
We are only looking for a set number of completes so don't wait and take the survey now! All participants who complete the entire survey will receive 250 Marriott Reward points.
Any Marriott Reward points you earn for survey completion will be transferred into your account at the end of every month.
It took me less than 10 minutes and I enjoyed telling them which of the ads I liked and which I thought were ugly and ineffective.
I hope everyone continues to post here about what surveys they're asked to fill out at what point reward level. I hadn't realized until I read the recent posts that different people would be chosen to respond to different surveys, according to their profiles.
