I believe it was a paid email also.
I've been a member of epoll for years and I can say they've had their ups and downs but seem to be doing ok now. I don't get a ton of offers from them, but they seem to go in waves. I also don't quite understand how they pick the amount of points they award for surveys. Sometimes I answer 1 or 2 questions and receive 500 points. Other times I do a lengthy survey for like 300 points. There doesn't seem to be any rhyme or reason behind it.
I usually cash out for $5 worth of mcdonalds gift certificates for 3500 points and stash them away for vacation. Overall, I like epoll, but you won't get rich from them, lol!
