I'm starting to get really frustrated with this issue and I'm hoping someone can help. I use Enhanced Email as my mail client and I have all accounts configured to have a "silent" ringtone for alerts. Yet whenever I get an email when my entire phone isn't silenced there's a little "bong" notification sound. It's killing me to have that going on every few minutes. I don't have any accounts configured in the stock Mail client have disabled mail syncing in the Gmail app. Anyone have any advice?
