With a mailing list, you can send out the same email message to a number of users simultaneously. The list is a collection of their email addresses, so when you send out one single email to the mailing list’s email address, firstname.lastname@example.org – for instance, it’ll be forwarded automatically to all the mailing list subscribers momentarily. Normally, people need to sign up for such a mailing list, but sometimes their e-mail addresses can be added manually as well, based on the program that is being used to manage the mailing list. You can use the feature to touch base with potential or current customers and to send them announcements, brand-new offerings and other sorts of info on a regular basis. This will demonstrate your desire to stay in touch with them and will boost the popularity of your website.
