How to mail in msg to computer

I think you meant to ask "How to send a message to a computer via mail?"

Unfortunately, it's not possible to send a physical mail message to a computer, as computers don't have a physical address or a mailbox. Computers are electronic devices that communicate through digital signals, not physical mail.

However, there are a few ways to send messages to a computer or a person who uses a computer:

1. Email: You can send an email to a person's email address, which is usually a combination of their name and a domain name (e.g., [email protected]). The email will be delivered to the person's email inbox, which is stored on a computer or a server.
2. Online messaging platforms: You can use online messaging platforms like Facebook Messenger, WhatsApp, or Slack to send messages to a person who uses a computer or a mobile device.
3. Instant messaging apps: You can use instant messaging apps like Skype, Google Hangouts, or Discord to send messages to a person who uses a computer or a mobile device.
4. Text messaging (SMS): You can send a text message (SMS) to a person's mobile phone number, which will be delivered to their phone's inbox.

In summary, while you can't send a physical mail message to a computer, there are many ways to send digital messages to a person who uses a computer or a mobile device.
