In the past 3months I've sent out about 6,400 mailers to UNIQUE addresses. Out of those 6,400 mailers:
1400 were a signed letter with a total of 14 responses, 1 closed deal, 1 under contract
5000 were postcards with 8 responses, 1 closed deal
So in total I've had 22 responses but it's gotten to a point where I'm averaging a call a day. I don't count a response as someone asking to be removed from a list or calling about a property that's not our specialty like a call yesterday for vacant land sale. I'm very specific about not sending to the same address for different types of lists and returned signed letters get updated immediately so that they aren't resent.
I'm just now starting my 2nd mailing to these same groups but will continue to create unique addresses at least until I hit 10,000. My ultimate goal is to take ALL responses and see if there are similarities in what the underlying factor is to getting a response.
I also want to add that I always provide a unique link to a form that can be completed on my website and of the 22 responses, 3 have gone directly to my site to provide their info. Just wanted to share that.
My lists are comprised of specific neighborhoods my partner and I want to "farm", absentee owners, properties from Driving for dollars, evictions, code compliance.
I handle all the marketing myself, from creating the material, lists and stuffing my own envelopes. Postcards were my design and just get uploaded to a mailing house.
Hope something in here was useful.
