Agree with many others that direct mail is not dead, yet you need a style that stands out from all the rest. To do that you need a professional, creative designer that understands your business and the kind of customers you are targeting. That said, postcards are very effective for all kinds of outreach efforts. It's easy to share and makes a more lasting impression than a business card. Key is to have your business card, postcards and landing page all branded. I recently worked with Howard Beauchamp and we connected on Alignable! Check him out @ www.howardcre8s.com.
