This isn't a scam. I do surveys for them all the time. They are always from Carole Adam. Lucky you, congrats!

Awesome!! Thank you!

Yes -TNS is a legit company! But do you remember doing a survey for them and entering the draw?
If so then rest assured that you had a lucky win. Congrats

If you did a survey for them, they do have draws! I've never been lucky to win, though!

So, congrats!

Wow! I do surveys all the time but never even hoped to win! Congratulations!
