I MUCH prefer a colorful cool witty cliver post card.

. $$ range and target areas)From that initial "dumped list" I prioritize records and then send out about 400 postcards and about the same number of letters per month.

I wanted to know what type of letter/postcard I should use and what criteria i should pick for generating my list.

I buy 90 Pound card stock from Amazon and then have Office Max cut it into postcard size and it is really inexpensive.I usually double or triple the money I've spent on my mailings.

If that's the case, send a mailer (if you're planning on sending a letter/postcard) to the address that's listed for the owner in public records.

I love the postcards too.

Spend the funds to send out post cards, driving for dollars, cold calling, etc...I launched a new campaign and within the last 3 days I was able to pick up 3 homes a lot cheaper than going through a wholesaler or MLS. 

I have heard of marketers reaching out to those individuals when the owner's address comes back as a RTS because of the address being vacant, unable to forward, or not deliverable as addressed.Can someone who follows up on these RTS leads tell me what you do with your postcards or yellow letters that get returned when the owner's address is vacant?  

At closing I joked that he had received 17 previous letters/post cards from us but had no recollection of them.

We use a combination of yellow letters, typed professional letters, and postcards.
