avsändares

Avsändare is a Swedish term meaning the sender of a message or item. The avsändare can be a person or an organization, and is usually contrasted with mottagare (the recipient). The term is used in postal, advertising, and digital communication contexts.

In postal correspondence, avsändaren is the person or organization that sends the item and is often required to provide a return address. The avsändares information helps the postal service return or verify items and can have legal implications for liability, privacy, and consumer protection.

In the context of electronic mail and messages, avsändaren refers to the entity identified as the sender in the From header. However, the displayed avsändare can be spoofed; technical standards such as SPF, DKIM, and DMARC are used to validate the sender's identity and reduce misuse. Some jurisdictions require clear avsändare information for certain communications, such as marketing or debt collection notices.

Etymology: the word derives from av- (a prefix meaning away or from) and sändare (sender). Avsändares is the genitive form meaning "the sender's."
