How to mail logout

I think you meant to ask "How to mail a logout?"

If you're asking about how to log out of an email account, here are the general steps:

1. Open your email account on your device (computer, phone, or tablet).
2. Click on your profile picture or username in the top right corner of the screen.
3. Click on "Sign out" or "Logout" from the dropdown menu.
4. Confirm that you want to log out by clicking "Yes" or "OK" in the pop-up window.

Alternatively, you can also log out of your email account by closing the browser or app, or by using the "Log out" button on the email client's main screen.

If you're asking about how to send a logout request to someone, it's not a standard practice to send a "logout" email. Instead, you can send an email to the person asking them to log out of their account or to close their session. For example:

"Hi [Name], I think you might have left your account open on your device. Could you please log out of your account to ensure your security?"

Please note that it's generally not recommended to share login credentials or ask someone to log out of their account, as it can compromise their security and privacy.
