Which one is a correct e-mail address?

Correct answer: abc@website.com. A valid e-mail address has one @ symbol, followed by a domain with a dot and an extension.

Background: An e-mail address has the form username@domain, where the @ sign separates the user’s name from the mail server’s domain.

• abs@website@info: It has two @ symbols.
• name.abc.com: It has no @ symbol.
• abc.website@com: The @ symbol comes before “com” without a proper domain.

Did you know? Ray Tomlinson sent the first networked e-mail in 1971 and chose the @ sign for addresses.

Memory trick: One @, then a domain with a dot and an extension.
