An emailer is a program that sends automated emails, typically to a list of recipients. A newsletter is a periodic mailing of information or announcements from a organization or individual.
Emailers are typically used for marketing and advertising purposes, while newsletters are used for distributing information about the organization or individual, sometimes with the goal of generating sales. .
While there are some key differences between emailers and newsletters, the two types of correspondence share many common features. For example, both emailers and newsletters typically use automated processing to send out messages on a regular basis.
Both also rely on lists of subscribers to deliver their messages to large numbers of people. And finally, both can be customized to emphasize different aspects of the message being sent.
So while there are some significant distinctions between emailers and newsletters, they both serve important purposes in the marketing and communication arenas. As long as an emailer is used in a responsible way and follows all applicable regulations, it can be a valuable tool for promoting your business or reaching out to your audience.
