A newsletter is a communication tool that is typically used to keep customers, employees, or other interested parties informed about happenings or new products at a company. It is also occasionally used as a way to market a company’s services.
The purpose of a newsletter can be different for each organization. Some newsletters may serve as an informational resource for customers and employees, while others may be used as a marketing tool to attract new customers or retain current ones.
Ultimately, the purpose of a newsletter is up to the individual or organization behind it.
