Probably benefits grow when you shift from simple emails to more complex ones. If you have to send quite a few emails per day and if you can do that quicker and/or better then there’s benefit in using the tools.

After all someone came up with an idea to do away something as simple as us writing ’BR, my name, my company’ in the end of the email - and pretty sure no one would give up that simple feature.

Ah, the good old ”unless you (and all of your perceived group) have already covered all the world, then this particular point is xenophobic/hypocritical/whatever”…
