How to Keep My Buyer's List "Warm?"

[Alvin Grier]

We've accumulated the email addresses (and in some cases phone numbers) from interested parties that have been interested in properties we've had for sale.

I'd like to do a better job at establishing and keeping a warm relationship between us and the potential buyer's.

I'm unsure of a good way to go about this. I've thought about creating an autoresponder list, where they get emails about real estate tips for our market or something like that, maybe once a month.

My goal is to turn those phone numbers and email addresses into real-life relationships.

The issue with the approach I just mentioned, is that they'd have to "opt-in" into that autoresponder list, you can't just manually add email addresses to that list.

I guess I could reach out to each person that's emailed us in the past and let them know about our opt-in list, and mention the benefits (I'm just thinking aloud, here).

What do you think is a good method to developing rapport with these people, in an effort to build real relationships between those that are willing to do so?

Also, what do you think about my idea that I mentioned in this post?
