Question

While sending an email which line describes the contents of the message?

Answer 1

Hello dear!

E-mail or electronic mail is a free, quick and reliable facilty for sending to anyone, anywhere and interesting anytime over the globe.
When we send any email the line which describes the contents of our message is $\boxed{Subject}$.

$\large{Extra \: Info:}$
It is really important to mention the subject in any email which we send because if we do not fill the subject then our mail is considered spam and is sent to the spam folder of the receiver.

Hope it helps!
