4: Promote Your Newsletter on Other Web Sites
Look around for web sites that complement rather than compete with your business. Then see if they'll do a co-registration deal with you by adding your newsletter opt-in to the newsletter that they offer during their newsletter subscription process. For example, About.com does this with my Online Shopping newsletter. When a reader subscribes to my newsletter, About.com asks whether the reader would like to subscribe to a complementary newsletter as well. For my column, it's the About House and Home newsletter, in which subscribers can receive information from About Guides on living, gardening, pets, and more.
