As someone who has mailed hundreds of thousands of postcards, I don't think it matters to be quite honest. 

I had a multiple step direct mail campaign (letters and postcards).  

Take the three names of the folks who called off your list, and send postcards to the rest.

If you’re doing letters now you could put the old list on postcards for a reduction in cost.

Even before we decided to sell the property we were regularly receiving direct-mail postcards, no-ring phone calls, texts, etc.  

Keep at the leadDon't give upSend postcards every weekBe doggedly persistent

it seems like an awesome service,Ive used it for around 20-30 postcards for properties I found D4D so far over the last month and a half, but honestly havent gotten any calls from it yet.

i have never mailed out post cards to an absentee owners list any suggestions of what to put on these post cards?

It's a neighborhood inside the 21213 zip code of Baltimore.When I see property listings for other townhomes in Belair-Edison, the neighborhood is referred as "world-famous belair-edison neighborhood" and other such lofty phrases.I get a postcard, text message, phone call or direct mail about once a week with offers to buy it from me.I also own two properties less than a mile from there in 21214, which I get exactly zero calls on.So, I'm wondering... why do investors want into this neighborhood so badly?
