Yesterday Scott Hargis sent me a copy of his e-mail marketing that he is sending to clients. I've talked before about how if you are building your business it's a good idea to keep regular contact with your past and potential customers by sending them e-mail and post cards. This doesn't replace face-to-face contact, it just reinforces it. Realtors do this with their customers so they expect it and recognize good marketing so don't be bashful about sending e-mail newsletters, post cards etc. In Scott's case he simply sends an e-mail with a photo-link to his "Recent work" gallery on his website. This can keep your name and work in front of your current and potential clients. If they don't which to receive the marketing piece they can just op-out (unsubscribe).
The point of VerticalResponse.com is that it simplifies the process of managing your mailing list and letting clients subscribe, unsubscribe to e-mail or post cards as well a creating and sending the marketing pieces. Managing your marketing with a tool like VerticalResponse.com actually improves the professional appearance of your marketing.
