Property:Email

Use email to identify some string as an has type::email address. This uses the built-in Type:Email

If you want to state an (annotated) email address in some article, the easiest way is to use the semantic templates Template:Mailbox (for emails of persons and organisations) or Template:Email (for emails of things that are not "agents" in the sense of FOAF). The usage of both templates is simple, and documented on their respective pages.

Note: "Electronic mail" is commonly abbreviated both as "e-mail" and as "email". In using "email" for the property we rank common usage above linguistic concerns.
