I've never received the email previously. BUT, I've never had so many opportunities to redeem.

In the last 2 months, between my husband & I, we've redeemed for CO and DL miles, as well as HH points. My husband was down to $5, and I was at about .10 at the beginning of June.

Perhaps those of us who received the email were redeeming our points recently. In the past, I was always waiting for $50 to be able to redeem for Hilton. Since adding CO & DL, not only am I receiving more surveys, but I'm redeeming more also.
