Difference Between Letter and Mail

Key Differences

A letter is traditionally understood as a written communication between individuals, often personalized and enclosed in an envelope, sent through the postal service or electronically via email. It's a form of communication that has been used for centuries, valued for its personal touch and deliberateness. Mail, on the other hand, refers to the broader category of items and documents that are processed and delivered by postal services or courier companies. This includes not only letters but also packages, magazines, advertisements, and other types of correspondence.
The composition of a letter usually involves a greeting, body, closing, and signature, tailored to the recipient with a specific message or information. It can be formal or informal, depending on the relationship between the sender and the recipient. Mail, in its broader scope, might not carry the same personal tone or detailed message as a letter. For example, packages may contain goods with an accompanying invoice rather than a personalized message, and magazines are designed for a general audience rather than an individual.
The purpose of sending a letter often revolves around personal communication, such as conveying thoughts, feelings, information, or conducting formal transactions like business correspondence. In contrast, the purpose of mail can range from personal communication to commercial, including advertising materials, ordered goods, legal notices, and more. The diversity of mail reflects the wide range of reasons individuals and entities use postal and courier services.
Delivery methods for letters typically involve postal services, which can vary from standard to express delivery options, depending on the urgency and the sender's willingness to pay for faster service. Mail, encompassing a wider variety of items, can utilize a broader array of delivery services, including specialized courier services for packages, certified mail for legal documents, and bulk mailing options for promotional materials.
The handling and regulations surrounding letters and mail also differ. While letters, especially personal ones, generally enjoy a degree of privacy and protection under postal regulations, the broader category of mail, including commercial and legal items, may be subject to more specific handling requirements, regulations, and scrutiny, especially when crossing international borders or when subject to customs checks.
