I went through a period earlier this year with no e-mail invitations. But that ended a few days ago when I got prompted to update my preferences. After doing that, I have gotten about an e-mail invitation a week. However. even when I was getting no e-mails, I still was able to do surveys by going to the e-rewards site and asking for them, and by using the e-rewards app.

FWIW, I have been a member for years. Always with just one account.

I mainly redeem for Hilton points, with occasional airline redemptions to keep lesser-used accounts active. Hilton only lets you redeem quarterly and I have a month to go to when I can again redeem. But I already have about $160. So by the time I can again spend $100 for 7,000 Hhonors points, I will be over two-thirds of the way to getting another 7,000. Hilton redemptions used to be instantaneous. Now they take a few hours, but still nothing to complain about.

It used to be that it took me three months to get a $100 in points. Now it sometimes takes half that time. So I am doing better right now with e-rewards than I ever have in the past. I'm sorry that your mileage is varying so much from mine.
