I didn't get the email either, but I was looking at the purchase points page yesterday because I was about 4,000 points short for a stay that my wife was planning, and the page had a blurb that said

"You've revealed a bonus of 100% more points on your purchase! Buy points today and get the award you want sooner than ever. This offer ends on July 18, 2016."

So it might be worth checking out.

In my case, I can buy 2,000 (1000+1000 free) points for $13.50 ($0.00675/point), up to 120,000 points (60k+60k) for $690 ($0.00575/point)
