A newsletter is a periodic e-mail newsletter which is sent out to subscribers. Due to its benefits, newsletters are used by websites with a wide range of activities: large and small shops, blogs, news services or even government websites.
This gives subscribers the chance to find out about news or updates that may be of interest to them. It is also common for e-commerce sites to send out special discount codes or information about promotions. Newsletters are important in maintaining contact with customers or people interested in a brand. A well-thought-out newsletter can be an effective sales promotion medium.
