I got one from UA as well.
Subject: Become a VIP in half the time
Earn over 60% more with VIP status through 2016. And earn 5 award miles per dollar through 2016
This year, you've dined 1 time with MileagePlus DiningSM (as of 10/1/15).
For a limited time, earn VIP status for the rest of the year and all of 2016 — plus 250 bonus award miles — once you've completed your 6th restaurant visit, instead of the usual 12.
