Driving 4 Dollars + Direct Mail Follow-up

[Rashonda Montgomery]

Hello BP -  I’m a newbie looking to begin my first driving for dollars direct mail campaign. My approach is to send a handwritten post card after performing a skip trace. My questions are around the follow-up process for the owners who do not call me after receiving the 1st mailer.

1. What type of mailer I should send next? A yellow letter, postcard, or email (this may or may not be an option; my understanding is 2.0 REITouch returns email addresses if found). 
2. How frequent should I mail before calling?
3. And when is the lead consider “dead”?
   

Thanks as always BP Community for your input!
