I tried opting in to the Insider program to get beta access for Halo Reach and everything seems to be working except for the email verification. I double(actually quintuple) checked the email, and it’s the right one. I tried sending a new confirmation email multiple times, but my inbox is still void of a Halo related message. I also checked the junkmail (though I removed all filters on gmail) and it’s nowhere to be seen.
I just hope this doesn’t keep me from getting a chance to gain beta access. I really want to get back into Reach 
Try this thread.
Quite a few people have been having issues with it. I would say the email servers are being overworked but it’s been months since the program opened, so it should’ve settled down by now.
If that thread doesn’t help, you could try changing the email address; I have one that likes to receive/reject emails depending on its mood, so it could be that.
Since flight invites are delivered via email, I’m afraid you’re going to need to get it working.
If it does work you should receive two emails; one titled ‘Please verify your email’, then one titled ‘Welcome to Halo Insider’.
