Recently I signed up to directly receive work emails, calendars and notifications to my cell phone. It has been positive in most situations, but I can't determine if it hurts my ability to "turn off" work.
This is actually a very big problem these days I find. Honestly there are proabaly 100's of pros and cons on this topic. To offer some advice all I could really say is that you need to stay disiplined and know when to turnoff.
