If they provide the individuals and send them the post card or yellow letter directly, why would I need to use listsource?

We generate a out-of-state absentee deal about 12,000 postcards ($6,000).  

My mailing list is all set up and I am going to order postcards as soon as I get done with this post.

Yellow letters typically convert better but cost more than postcards - but if you spend the same on each you should get similar results - though that will depend somewhat on your target market and competition.3.

Like @Greg H. said, the cost would be higher.I keep sending post cards, I am doing manually, lets see the result

@JD RuizMake sure you're sending the first batch as a postcard so that for the dead addresses when they bounce, you can knock them off the list before mailing yellow-letters.

I BUY REAL ESTATE, do you want to sell - Hello I thought I'd send you a letter to let you know that I am a real estate investor looking to control some equity and make moneyHello, I'd like to make a low ball offer and assign my contract for a profitI am an absentee of many properties in Maryland and other states and I receive hundreds of letters a year, some on silly yellow paper with stick figures of people holding dollar signs, or little drawings of houses with  a sad face, even slick full color post cards from people who want to buy (steal) my properties.Most are not serious and don't have money.

I did a direct mail campaign of about 2,500 post cards to buy property in the Maryland area.

I’m getting my systems in place but I’m planning on postcard (clean up address generic meaning I don’t market with anything about foreclosure), first letter intro & state I got their information from public records about pre-foreclosure & offer for cash as is sale, second letter benefits of short sale, third letter negative impacts of foreclosure.

He does a ton of postcard marketing to owners so get a lot of listings, so you may get some deals before they hit the mls.
