Willing to bet that it's not really maintenance. It's just the sign they hang whenever the system goes down (for any reason). Wait 10 minutes and it will be up again.
I find I have to change my settings at the beginning of every month or more, and I still get new release etc e-mails about 50% of the time.
Like someone else noted, I get 100% of the e-mails asking me to rate coins that I purchased - wish I could opt out of those.
