And with it comes change. Change your marketing strategy! Stop spamming people with email after email and try an old-fashioned approach instead: personal marketing.
Simple order up some business cards or postcards from ePrint and go door-to-door around your local business area. Don't try to sell anything, just stop in and politely introduce yourself and your company; let them know who you are, what you're about and hand them your contact information.
In this, the digital age, actual physical interaction is a rare and worthwhile pursuit.
