informal note

Casual written message

An informal note is a brief, casual written message—less structured than a formal letter or memo.

It might be jotted on paper, left on a desk, or sent electronically: She left an informal note thanking him for dinner.

The term emphasizes the relaxed tone and minimal formality, often between people who know each other.
