A letter is a written message conveyed from one person to another through a medium. Something epistolary means that it is a form of letter writing. The term usually excludes written material intended to be read in its original form by large numbers of people, such as newspapers and placards, although even these may include material in the form of an "open letter". The typical form of a letter for many centuries, and the archetypal concept even today, is a sheet of paper that is sent to a correspondent through a postal system. A letter can be formal or informal, depending on its audience and purpose. Besides being a means of communication and a store of information, letter writing has played a role in the reproduction of writing as an art throughout history. Letters have been sent since antiquity and are mentioned in the Iliad. Historians Herodotus and Thucydides mention and use letters in their writings.
An envelope is a common packaging item, usually made of thin, flat material. It is designed to contain a flat object, such as a letter or card.
A letter of credence is a formal diplomatic letter that designates a diplomat as ambassador to another sovereign state. Commonly known as diplomatic credentials, the letter is addressed from one head of state to another, asking them to give credence to the ambassador's claim of speaking for their country. The letter is presented personally by the ambassador-designate to the receiving head of state in a formal ceremony, marking the beginning of the ambassadorship.
Postal cards are postal stationery with an imprinted stamp or indicium signifying the prepayment of postage. They are sold by postal authorities. On January 26, 1869, Dr. Emanuel Herrmann of Austria described the advantages of a Correspondenz Karte. By October 1, 1869 the world's first postal card was produced by Austria-Hungary. They caught on quickly. By the end of 1870, Great Britain, Finland, Switzerland and Württemberg joined the countries issuing postal cards. In the United States, they were first produced in 1873. Some of the forms taken by postal cards include the regular single card which may be commemorative or definitive, attached message-reply cards, airmail postal cards, and official postal cards used for official government business with a "penalty for private use".
Paper size standards govern the size of sheets of paper used as writing paper, stationery, cards, and for some printed documents.
A piece of postal stationery is a stationery item, such as a stamped envelope, letter sheet, postal card, lettercard, aerogram or wrapper, with an imprinted stamp or inscription indicating that a specific rate of postage or related service has been prepaid. It does not, however, include any postcard without a pre-printed stamp, and it is different from freepost for preprinted cards issued by businesses. In general, postal stationery is handled similarly to postage stamps; sold from post offices either at the face value of the printed postage or, more likely, with a surcharge to cover the additional cost of the stationery. It can take the form of an official mail issue produced only for the use of government departments.
A stamped envelope or postal stationery envelope (PSE) is an envelope with a printed or embossed indicium indicating the prepayment of postage. It is a form of postal stationery.
Mulready stationery describes the postal stationery letter sheets and envelopes that were introduced as part of the British Post Office postal reforms of 1840. They went on sale on 1 May 1840, and were valid for use from 6 May. The Mulready name arises from the fact that William Mulready, a well-known artist of the time, was commissioned to illustrate the part of the letter sheets and envelopes which corresponded with the face area.
An aerogram, aerogramme, aérogramme, air letter or airletter is a thin lightweight piece of foldable and gummed paper for writing a letter for transit via airmail, in which the letter and envelope are one and the same. Most postal administrations forbid enclosures in these light letters, which are usually sent abroad at a preferential rate. Printed warnings existed to say that an enclosure would cause the mail to go at the higher letter rate.
Registered mail is a postal service in many countries which allows the sender proof of mailing via a receipt and, upon request, electronic verification that an article was delivered or that a delivery attempt was made. Depending on the country, additional services may also be available, such as:
A wedding invitation is a letter asking the recipient to attend a wedding. It is typically written in the formal, third-person language and mailed five to eight weeks before the wedding date.
A business letter is a letter from one company to another, or such organizations and their customers, clients, or other external parties. The overall style of letter depends on the relationship between the parties concerned. Business letters can have many types of content, for example to request direct information or action from another party, to order supplies from a supplier, to point out a mistake by the letter's recipient, to reply directly to a request, to apologize for a wrong, or to convey goodwill. A business letter is sometimes useful because it produces a permanent written record, and may be taken more seriously by the recipient than other forms of communication. It is written in formal language.

Diplomatic correspondence is correspondence between one state and another and is usually of a formal character. It follows several widely observed customs and style in composition, substance, presentation, and delivery and can generally be categorized into letters and notes.
A salutation is a greeting used in a letter or other communication. Salutations can be formal or informal. The most common form of salutation in an English letter includes the recipient's given name or title. For each style of salutation there is an accompanying style of complimentary close, known as valediction. Examples of non-written salutations are bowing, waving, or even addressing somebody by their name. A salutation can be interpreted as a form of a signal in which the receiver of the salutation is being acknowledged, respected or thanked. Another simple but very common example of a salutation is a military salute. By saluting another rank, that person is signalling or showing his or her acknowledgement of the importance or significance of that person and his or her rank. Some greetings are considered vulgar, others "rude" and others "polite".
A valediction, or complimentary close in American English, is an expression used to say farewell, especially a word or phrase used to end a letter or message, or a speech made at a farewell.
In philatelic terminology a letter sheet, often written lettersheet, is a sheet of paper that can be folded, usually sealed, and mailed without the use of an envelope, or it can also be a similar item of postal stationery issued by a postal authority. Letter sheets derive from the form in which written correspondence was made up before the mid-19th century—letters were written on one or more sheets of paper that were folded and sealed in such a way that the address could be written on the outside.
In philately a wrapper is a form of postal stationery which pays the cost of the delivery of a newspaper or a periodical. The wrapper is a sheet of paper, large enough to wrap around a folded or rolled newspaper and with an imprinted stamp to pay the cost of postage. Some catalogs and reference books refer to a wrapper as postal bands which comes from the French term bandes postale. Still others refer to it as a newspaper wrapper or periodical wrapper.
Letterlocking is the act of folding and securing a written message on papyrus, parchment, or paper, without requiring it to be contained in an envelope or packet. It is a traditional method of document security that utilizes folding and cutting. The process dates to the 13th century in Western history, corresponding with the availability of flexible writing paper.
