No one is on email anymore -- how do you handle this?

Greetings all,

This is my first post here -- I'm in email marketing over 15 years.

I'm finding that whatsapp and similar have neatly uprooted email use.

People who used to be available by email are simply not around anymore.

No echo-back.  Simply silence and disconnect.

Surely this is not news to anyone here.

Is this topic already discussed elsewhere in the forum?
