Since 1981, the SMTP (Simple Mail Transfer Protocol) defines how internet hosts can send e-mail, and it is still widespread. Newer social media web sites may strive to replace it for certain tasks, but even they still require SMTP, even if it is just for sending verification mails on account registration.
