Why not just turn off all notifications but e-mail (or at least make them silent), and then only set audible notifications for emails that match a filter? There will undoubtedly be false positives and negatives in any such filter, but it seems like it would enable you to open the email app to check email far less often.
I like the filter idea then that woman you've been waiting to hear back from and whomever else, then that reduces the attention shifting thing except when it's worth it. Man, he's lucky his poison is email. It's the perfect medium to ignore for hours, well, unless it's something good.
Oops, I just made the assumption that the person was male posting that. Yikes. Not good. It really isn't. I didn't even look at the username to see if there was a clue there. OK, yeah lot's of other possible mistakes there, too. LOL. Fuck. Not exactly welcoming to women or others who don't fit what I said to post shit like this now is it, Marmot.
