One difference is that this controls your notifications as well. If I decide to only check email 3 times per day, then I have to turn notifications off for that to be effective. This means I may miss emails which need a reply sooner.

Before you let a third-party intercept all your mail (WTF) why not simply use a tool like Llama or Easer or Tasker or anything like that for Desktop to selective enable and disable notifications per app for certain times of day?

How is that different from this? You'd still be missing email that needs a reply sooner.

One useful difference is that you can set exceptions (i.e. email addresses that you want to receive emails from immediately).

Just let them call you if it is urgent?
