    Ray Tomlinson created the first email system in 1971 called CPYNET which allowed electronic mail over the ARPANET network using the @ symbol to separate the local and host parts of addresses. In the 1970s, IBM began transferring mail between individuals and in 1982 Shiva Ayyadurai composed a copyright registration for an application called Email. Common types of email include webmail accessed through a browser, email client software programs, and protocols like SMTP for transfer, POP for one-way download, and IMAP for two-way sync between servers and clients.

    History of Email

    In 1971, the first electronic mail (email) was created by


    Ray Tomlinson. CPYNET allowed the first networked
    electronic mail over the ARPANET. The addresses
    contained the @ character as a separator between local
    part and host. 1974 IBM provided mail transfer between
    individuals. In 1982, Shiva Ayyadurai composes a US
    copyright registration, for a work named Email.
    Types of email:
    Webmail - it is an email service that can be accessed using a

    standard web browser. e.g. Gmail, AOL mail, mail fence,

    and Proton mail, Outlook, Hot Mail, Yahoo.

    Email Client Software - IT is a computer program used to

    access and manage a user’s email. e.g. MS Access.


    Types of Email Protocol
    These are common email protocols:
    SMTP(Simple Mail Transfer Protocol)
    SMTP is the principal email protocol that is responsible for the
    transfer of emails between email clients and email servers.
    POP (Post Office Protocol)
    Email clients use the POP protocol support in the server to
    download the emails. This is primarily a one-way protocol and does
    not sync back the emails to the server.
    IMAP (Internet Message Access Protocol)
    IMAP Protocol is used to sync the emails in the server with the
    email clients. It allows two-way sync of emails between the server
    and the email client, while the emails are stored on the server.
