I noticed that I had missed some flight invites in the past because I was expecting to get some sort of an email about being invited. So when I didn’t get anything, I figured that I had just not been selected. When I checked back here on Halo Waypoint though, I saw that I had messages from 343 with information about the flights. I checked through my settings and only see options to receive WEB notifications when I’m logged in. Is there any way to get email notifications when you receive a message?
