Email is a method of transmitting and receiving messages using electronic devices. It was conceived in the late–20th century as the digital version of, or counterpart to, mail. Email is a ubiquitous and very widely used communication medium; in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries.
A chain letter is a message that attempts to convince the recipient to make a number of copies and pass them on to a certain number of recipients. The "chain" is an exponentially growing pyramid that cannot be sustained indefinitely.
The mail or post is a system for physically transporting postcards, letters, and parcels. A postal service can be private or public, though many governments place restrictions on private systems. Since the mid-19th century, national postal systems have generally been established as a government monopoly, with a fee on the article prepaid. Proof of payment is usually in the form of an adhesive postage stamp, but a postage meter is also used for bulk mailing.
A Christmas card is a greeting card sent as part of the traditional celebration of Christmas in order to convey between people a range of sentiments related to Christmastide and the holiday season. Christmas cards are usually exchanged during the weeks preceding Christmas Day by many people in Western society and in Asia. The traditional greeting reads "wishing you a Merry Christmas and a Happy New Year". There are innumerable variations on this greeting, many cards expressing more religious sentiment, or containing a poem, prayer, Christmas song lyrics or Biblical verse; others focus on the general holiday season with an all-inclusive "Season's greetings". The first modern Christmas card was by John Calcott Horsley.
Mail is an email client included by Apple Inc. with its operating systems macOS, iOS, iPadOS, watchOS, and visionOS. Mail grew out of NeXTMail, which was originally developed by NeXT as part of its NeXTSTEP operating system, after Apple's acquisition of NeXT in 1997.
Various anti-spam techniques are used to prevent email spam.
A Joe job is a spamming technique that sends out unsolicited e-mails using spoofed sender data. Early Joe jobs aimed at tarnishing the reputation of the apparent sender or inducing the recipients to take action against them, but they are now typically used by commercial spammers to conceal the true origin of their messages and to trick recipients into opening emails apparently coming from a trusted source.
A bounce message or just "bounce" is an automated message from an email system, informing the sender of a previous message that the message has not been delivered. The original message is said to have "bounced".
A greeting card is a piece of card stock, usually with an illustration or photo, made of high quality paper featuring an expression of friendship or other sentiment. Although greeting cards are usually given on special occasions such as birthdays, Christmas or other holidays, such as Halloween, they are also sent to convey thanks or express other feelings.
Email fraud is intentional deception for either personal gain or to damage another individual using email as the vehicle. Almost as soon as email became widely used, it began to be used as a means to defraud people, just as telephony and paper mail were used by previous generations.
Email marketing is the act of sending a commercial message, typically to a group of people, using email. In its broadest sense, every email sent to a potential or current customer could be considered email marketing. It involves using email to send advertisements, request business, or solicit sales or donations. Email marketing strategies commonly seek to achieve one or more of three primary objectives: build loyalty, trust, or brand awareness. The term usually refers to sending email messages with the purpose of enhancing a merchant's relationship with current or previous customers, encouraging customer loyalty and repeat business, acquiring new customers or convincing current customers to purchase something immediately, and sharing third-party ads.
Push email is an email system that provides an always-on capability, in which when new email arrives at the mail delivery agent (MDA), it is immediately, actively transferred (pushed) by the MDA to the mail user agent (MUA), also called the email client, so that the end-user can see incoming email immediately. This is in contrast with systems that check for new incoming mail every so often, on a schedule. Email clients include smartphones and, less strictly, IMAP personal computer mail applications.
Email spoofing is the creation of email messages with a forged sender address. The term applies to email purporting to be from an address which is not actually the sender's; mail sent in reply to that address may bounce or be delivered to an unrelated party whose identity has been faked. Disposable email address or "masked" email is a different topic, providing a masked email address that is not the user's normal address, which is not disclosed, but forwards mail sent to it to the user's real address.
Easter postcards are a form of postcard that people send to each other at Easter. They have now mostly changed to e-cards rather than postcards, but their purpose remains the same.
Windows Live Mail is a discontinued freeware email client from Microsoft.

Outlook.com, formerly Hotmail, is a free personal email service offered by Microsoft. This includes a webmail interface featuring mail, calendaring, contacts, and tasks services. Outlook can also be accessed via email clients using the IMAP or POP protocols.
The Gmail interface makes Gmail unique amongst webmail systems for several reasons. Most evident to users are its search-oriented features and means of managing e-mail in a "conversation view" that is similar to an Internet forum.

Graymail is solicited bulk email messages that don't fit the definition of email spam. Recipient interest in this type of mailing tends to diminish over time, increasing the likelihood that recipients will report graymail as spam. In some cases, graymail can account for up to 82 percent of the average user's email inbox. Graymail was described in 2007 and 2008 by researchers at Microsoft Research looking to improve spam filtering as “messages that could reasonably be considered either spam or good ” hence the name “graymail” was chosen to signify the subjective nature of the classification. A 2008 paper presented at the Fifth annual Conference on Email and Anti-Spam (CEAS) describes graymail as "messages that some users value and others prefer to block". In 2011 a report by The Radicati Group referred to graymail as "newsletters or notifications that a user may have signed up for at one time but no longer wants to receive".
