A newsletter is a regular publication, usually a few pages long, that shares news and information with a specific group of people who have something in common. Schools send newsletters to parents about upcoming events and classroom activities. Museums send newsletters to members about new exhibits. Companies send newsletters to customers about new products or special offers.

Originally, newsletters were printed on paper and mailed to people's homes, which could take days to arrive. Today, most newsletters are sent by email and arrive instantly. You might subscribe to a newsletter about your favorite video game, science topics, or sports team. The word subscribe means you've signed up to receive it regularly, whether that's daily, weekly, or monthly.

The key thing about newsletters is that they're regular and focused. Unlike a newspaper, which tries to cover everything happening in the world, a newsletter concentrates on topics its specific audience cares about. A chess club newsletter tells members about upcoming tournaments and strategy tips. A nature center newsletter shares updates about local wildlife and hiking trails. Think of newsletters as a way for groups to stay connected and informed about the things that matter most to them.
