(sorry if I am incorrectly attributing credit) suggesting that rather than sending a stream of YL's to instead mix it up some, do a YL, a postcard, a postcard, then another YL.  

Yellow letters seems to get a higher response rate then a postcard, but a postcard is cheaper allowing you to send more.

Why would a Realtor being using a "handwritten" yellow letter rather than a professional white letter or postcard?

Right now as I type this, I have a list of FSBOs that need to be called and a stack of post-cards that were returned as "vacant".

With that list, I will be launching a 6-12 month direct mail campaign (combination of yellow letters and postcards), with the hopes of wholesaling any deals I come across.My question is, are there any additional other criteria I should be looking?

I am planning on starting a direct mail campaign to them and I was wondering if anyone has an example of a letter or postcard that would be good to send to this list?

Postcards.

Postcards slow down the phone a lot however the majority of the calls are a better quality although the quality calls are not as abundant as yellows.

Out of state absentees have slightly different motivations, so you might market to them with separate letters/postcards, etc.But we like 'em both!

DorseyI should also add that direct mail isn't the only way to create business1) center of influence promotion 2) lead sites like www.webuyhouses.com3) networking on BPWhen doing direct mail there are several sites I would use if I didn't own mine. 1) click2mail2) absolutely would try Jerry3) postcard mania
