Email is a method of sending and receiving digital messages over the internet. It is short for electronic mail and has become one of the most widely used communication tools.

To send an email, you need the recipient's email address, subject line, and the actual message. You can also attach files, such as documents or images, to the email.

To receive email, you need an email account with a provider, such as Gmail, Outlook, or Yahoo. Emails sent to your email address will appear in your inbox, and you can read, reply to, or delete them as needed.
