This one really drives me up the wall. It's as if an email has travelled hundreds of miles by foot, entered your home, found you asleep in bed, and wants to know how you are with a nice cup of tea and a chocolate hobnob
This is not jargon! I'm so guilty of all of these - how else do you sign off an email?!“I’ll drop you an email”
“Regards”
“All the best”
“Many thanks”
