That's not my experience.
I use email. At work they use email. My mom uses email.
Email is just "there" at this stage. Your emails appear in your inbox and you're not really constrained by a provider.
I was taking aim more at the comparison with twitter and facebook which require constant engagement.
With email you just get it the way you want it, on your terms mostly.
Sounds pretty perfect.
