This is a very good approach. I have become ruthless at removing inbound interruptions from my devices:

I have all notification pop-ups disabled across all of my devices, with the sole exception of an incoming phone call (unless the caller is not in my contacts list, in which case it goes straight to voicemail without ringing my phone).

Beyond notifications, all badges are also disabled across all devices, with the sole exception of text messages (if I unlock my phone and go to the home screen, I can see that I have unread text messages).

This enables me to live largely in a pull fashion, without every communication channel constantly breaking my flow.
