E-newsletters
E-mail newsletters are a good way to increase the recognition of your brand, notify potential customers about special initiatives, or just catch up. Folks can easily subscribe and unsubscribe to your newsletter, so you have the secure knowledge that they are genuinely interested in what you have to say. And by keeping track of which links have been followed, you can gauge what is of interest to your people, and base future mailings (or even website content) on that information.
