Do you say writting or mailing in an email

In an email, you would typically use the phrase "writing" instead of "mailing". This is because emails are a form of written communication, and you are sending a message electronically rather than physically mailing a letter.

For example:

You wouldn't say "I'm mailing to ask you a question" or "I'm mailing to confirm our meeting time" because those phrases imply sending a physical letter or package, which is not the case with an email.

So, to summarize: in an email, you would use the phrase "writing" to refer to the act of composing and sending a message, rather than "mailing".
