Question

When is it not appropriate to send a message via e-mail?

Answer 1

I'd say when it's something personal, like say, telling someone their grandpa died, or breaking up with them, etc. 

Answer 2

when dealing with highly emotional issue

Step-by-step explanation:

It is not appropriate to send a message via email when something emotional and personal is happening. The correct thing is to wait for this period to pass and then send a professional and formal message, without the interference of emotional issues that can change the real meaning of your message. When sending an email message, this message should be sent at a rational and impartial time to any emotion.
