NOD Lists & How to Organize

[Lian L.]

Hello, Bigger Pockets cohorts,

I'm getting started with marketing, and I'm getting NOD lists from a title company. I'm at the point where I can collate the information and send out mailers to the people on the list, but this leaves me with a few questions:

1. How should I update my database when I get new lists every week or two?
2. How should I remove people from my list that ask to be removed? The issue here is that I can remove them, but they will probably be on the new list I receive. Is there any way to auto-update or auto-check?

What are you experts using? Are you automating this process somehow? I'm very interested in getting this ball rolling.

Thanks so much for your help!
