Hi Dan,
I too am about to send out some marketing to expireds, so hoping for a better response than I've had for the YLs. As someone who is working on a tight budget it was extremely frustrating to me about what happened with my first yellow letter order. I did speak to someone at the company and I so wish I had a recording of the order because I never would have ordered a list of people who were owner occupied. If I wanted to market to owner occupieds, I could just blanket a neighborhood or zip code, WHY would I purchase such a list????? RIDICULOUS!! The lady I had ordered from also suggested which YL to use saying they using get a 10% response rate. Well, it's been the third week of my 5 week YL campaign of 100 per week and I still have only received 4 total calls from the first week, all telling me thanks but my house is not for sale. At least the people who called were nice. But I did want to post about it to help others who are brand new to list buying and yellow letter buying for them to very careful and KNOW exactly what they are buying. Another thing I would do differently (other than I will not use the same company for my future YL because I also was unhappy about how they responded to me when I realized what my list was), is to get all the yellow letters sent to me so I can mail them out myself when I want and how many I want at a time.
As far as list purchasing goes, I just bought a list from listsource.com for owner absentee as well as some other criteria and am planning to mail marketing pieces to 50 owners at a time every 2 - 3 days. I was able to download my list immediately so I could mail merge it to my marketing pieces. One of my mentors who has been marketing successfully to sellers mentioned to use your list and market to them every 4 - 6 weeks, that being consistent is the name of the game.
I would love to know which list companies you use and what kind of response you get.
