What sound mail

I think you meant to ask "What is the sound of mail?"

The sound of mail is often associated with the rustling or crinkling of envelopes or packages being opened, or the sound of mail being sorted and processed at a post office or mail center. Some people might also associate the sound of mail with the sound of a letter being delivered to their doorstep, which could be a knock on the door or the sound of a mail carrier dropping off a package.

If you're looking for a specific sound effect, you might be thinking of the sound of a letter being opened, which could be represented by a gentle rustling or crinkling noise. Alternatively, you might be thinking of the sound of a package being unwrapped, which could be represented by a more dramatic rustling or tearing noise.
