A newsletter is a type of electronic publication that is typically sent out to a large group of people. The content of the newsletter is typically focused on a specific topic, and it can be updated regularly.
A newspaper, on the other hand, is a printed publication that is typically distributed to a much smaller group of people. The content of a newspaper is typically updated less frequently than the content of a newsletter, and it often includes more general news coverage.
The main difference between newsletters and newspapers is that newsletters are typically focused on a specific topic, while newspapers are more general in their coverage. Additionally, newsletters are typically sent out periodically, while newspapers are usually published once a week or once every other week.
Finally, newsletters are typically smaller in size than newspapers, while newspapers can be quite large.
