For experienced wholesalers and others who market direct to sellers, what's the best "bang for your buck" - postcards or yellow letters?

Hi, it's my first time that I ordered from yellowletters.com and I hope I didn't do something wrong. I just opened my mailbox and found all of the postcards in there. I thought they were going directly to the persons ...

If you are spending money sending yellow letters, make sure your answering service doesn't run out of space.I probably get around one yellow letter a week for one of my rentals.  

@Rochelle Wilkinson Yup, there are many paths one can take to succeed in life -- you don't always have to follow the same yellow brick road as everyone else.Sometimes, I think too much education can be a bad thing...

I am not an expert in marketing but sending out post cards and yellow letters is strictly a numbers game.

This includes the initial phone call, driving out and meeting the owner at their house, follow-up until I have signed contract back, and the BS associated with title problems, seller's getting cold feet and trying to back out of contracts, and all the other stuff that comes up from contract signing to actually settling on the house.BEST PERFORMING MAIL PIECE:Handwritten letter on yellow lined paper with handwritten invitation (A6) sized envelope in random colors (pink, light blue, yellow, etc)I have graphics on BOTH the letter and the envelope- things like dollar signs, stars, arrows, houses, etc- whatever random stuff I could think of to make the letter more eye catching and 'WTF' eliciting when opened by the homeowner, so they would actually read it.SECOND BEST PERFORMING MAIL PIECE:5.5 x 11 inch yellow post card (big post card) with somewhat handwritten looking font.  

I haven't used a YL campaign in the last 18 months, but I would like to augment YL into a drip campaign.   Can you recommend a company that can, reliably, do a few thousand a month?

I had several marketing streams active but my largest and typically most successful is the direct mail marketing I do with yellow letters. 

Has anybody else had the problem with competing companies with the same name, such as Yellow Letters and Yellow Letters Complete?  

I use @Jerry Puckett to mail out all my yellow letters.
