From what I can tell, the problem is that their emails are not reaching certain domains. I have an outlook.com email address and a few days ago I stopped getting login & withdrawal emails from btc-alpha (which is a problem since you need to get email to withdraw).

I created a new account using my work domain & am getting all emails (including withdrawals) just fine - but BTC is still stuck on my other account.

The problem w/ opening support tickets is that you can't tell if they reply, since you can't get emails from them - very frustrating.

If anyone has another way of contacting support please post.
