I think you meant to ask "What is an email address?"
An email address is a string of characters that identifies a mailbox on an email server. It typically consists of a local part (the part before the "@") and a domain (the part after the "@"). For example:
The local part is usually a combination of letters, numbers, and special characters, while the domain is usually a company name or a top-level domain (such as.com,.org, or.net).
Email addresses are used to send and receive emails, and they are usually used to identify a person or organization on the internet.
