Some high level help with Mailers (what NOT to do)

have a typo in the phone number. That was a waste of 800 post cards plus some angry dude in Texas. 

But really, it’s not so much what you put in the letter or post card but everything after you get the call. Do you sound profession on the phone? Do you actually answer the phone or call back in a timely fashion? Do you show up to appointments on time? So many factors that control the outcome over the piece of mail. Keep it simple and use what’s already provided by the big mail companies. Do you mail consistently? Write the letter on toilet paper but mail it monthly and the ones who need you will call.
