Hi, I'm Bill Bailey — aka Dr Bill.

Real-Estate-Agent-Lists.com isn't a company. It's me. One person, with a PhD in Information Systems and over 20 years of experience collecting, cleaning, and selling specialty data on the internet. I built this business from scratch and I still run every part of it — the data collection, the quality checks, the updates, and the customer support. When you buy a list from me, you're dealing directly with the person who made it.

I mention this because the list business has a trust problem. There are a lot of vendors selling recycled, outdated, or outright junk data behind generic websites with no name attached. You submit your credit card, download a file, and hope for the best. If the data is bad, good luck finding a human to talk to.

That's not how I operate. I've staked my name and reputation on data quality since 2002 and I'm not about to stop now.

How I Got Here

I've been obsessed with data for as long as I can remember. After earning a degree in Computer Science and Statistics at Florida State University, I went on to complete a PhD in Information Systems. (Yes, I really am Dr. Bill.) I spent six years as a college professor before jumping into the consulting world, building data-driven web applications — including some of the first dynamic websites on Microsoft's original web server back in 1997.

In 1999, I partnered on a dot-com venture. It failed. But in the process, I learned something valuable: how to systematically collect and organize professional data from the internet. That skill became the foundation of everything I've built since.

I launched my first data site in 2002, selling physician contact lists — one of the first (maybe the first) to offer specialty professional data at prices small businesses could actually afford. The business grew quickly as I expanded into dentists, chiropractors, lawyers, and eventually real estate agents.

I've been selling real estate agent lists at this site since 2006 — that's nearly 20 years of continuous operation, updates, and refinement. I also maintain Physician-Lists.com and Business-Lists.com.

What Makes My Lists Different

My real estate agent database currently covers over 2.1 million licensed agents across all 50 states and the District of Columbia, with contact data verified and updated on a regular schedule. I do two major data refreshes per year with monthly email cleaning in between. Every list purchase includes 12 months of free updates so your data stays current.

Because I control the entire pipeline — collection, processing, verification, and delivery — I can guarantee 96% accuracy on every list I sell. If your data doesn't meet that standard, I'll make it right with a prorated refund or replacement records. No ticket system, no runaround. You'll be dealing with me.

I also launched Zap Contact, my own email marketing platform, specifically because I watched my customers struggle with cold email. The major platforms (MailChimp, Constant Contact, etc.) prohibit purchased lists, which made it hard for my customers to actually use the data they bought. Zap Contact solves that — it's designed for outreach to professional contact lists.

My Guarantee

If you buy a list from me and you're not satisfied, I will personally make it right. That's not a corporate policy — it's a promise from the person whose name is on the business. I've been doing this for over two decades because I treat every customer the way I'd want to be treated.

To your success,

Bill Bailey
