About Mark Castagna

Introducing a dedicated real estate professional serving the Nature Coast, with a focus on Citrus County, including Crystal River, Citrus Springs, Dunnellon, and Pine Ridge.

With over two decades of industry experience and a track record of several hundred successful transactions, this agent is committed to providing personalized, one-on-one service to each client. Supported by a team of experts, they guide clients through every aspect of the home-buying process, including mortgage and insurance options.

Utilizing the Realtors Multiple Listing Service, this agent tailors home searches to meet individual client needs. Clients receive timely updates on current listings, ensuring they are among the first to know when new properties become available.

A strong advocate for ongoing education, this agent dedicates significant time to market research and professional development, enhancing their ability to serve clients effectively. Their passion for real estate and helping others find their ideal home is evident. Recognizing that purchasing a home is often one of the most significant financial decisions one can make, they emphasize the importance of working with a knowledgeable professional who understands contract complexities and possesses strong negotiation skills. Their mission is clear: "To Exceed My Customers' Expectations."

Originally from western New York, this agent graduated from LeMoyne College before relocating to the west coast of Florida. After spending 30 years in Florida, they moved to the Blue Ridge Mountains of North Carolina, only to return to Crystal River in 2018, drawn back by the warmth and beauty of the area.

As a licensed real estate broker, they hold several prestigious certifications, including Advanced CDPE (Certified Distressed Property Expert), C-REPS (National Association of Broker Price Opinion Professionals), and CIAS (Certified Investor Agent Specialist), along with the Short Sales and Foreclosure Resource (SFR) designation. They are a proud member of the National Association of Realtors (NAR), Florida Association of Realtors (FAR), Pinellas Realtor Association (PRO), and the Realtors Association of Citrus County (RACC).

This agent looks forward to assisting you with all your real estate needs.

If you need to reach working real estate agents in Citrus County, Florida, this list was built for you. Mortgage lenders prospecting for referral partners, title companies seeking closing relationships, PropTech platforms launching in new markets, CE providers filling course seats, insurance agents selling E&O or home warranty products, and recruiters targeting licensed talent all rely on this data to run campaigns that actually land in front of the right people. These are not leads — they are professional contacts at the center of every real estate transaction in the county.

When you buy a Citrus County real estate agent email list, you are making a direct marketing decision that either pays off or wastes your budget depending entirely on data quality. With {{AGENT_COUNT}} actively licensed agents and {{CELL_COUNT}} records that include verified cell phone numbers, this list gives you multiple channels to work from a single purchase. Every record is sourced from state licensing authority data, so you are not getting scraped web results or stale spreadsheets recycled from a broker down the street.

Why Buy a Citrus County Real Estate Agent Email List From Dr Bill

Dr Bill has been in the list business since 2005 and has sold over 31,000 lists to marketers who need data they can actually use. Every email on this list is verified, cleaned monthly, and the entire database is completely refreshed bi-annually. That discipline produces a 96% deliverability guarantee — a number the cheap list vendors on Fiverr or generic data aggregators simply cannot match because they do not invest in ongoing maintenance. You get what you pay for, and here you are paying for process.

The data is sourced directly from Florida's state real estate licensing board, which means every agent on the list holds an active license at the time of pull. New emails are added weekly as agents enter the market, so the list stays current between refresh cycles. If deliverability falls below 96%, replacements are provided — no runaround, no fine print. That guarantee exists because the data earns it.

How to Use This Citrus County Agent List

The most immediate application is email outreach through cold-email platforms designed for high-volume prospecting. Zap Contact at zapcontact.com is built specifically for this use case and integrates cleanly with this list format. Beyond email, the same records support direct mail campaigns, SMS and phone outreach using the cell numbers, and LinkedIn audience matching by uploading emails to build a custom ad audience targeting Citrus County agents specifically.

You can also segment the list by license type, separating broker-owners from sales agents to tailor your message appropriately. A recruiting pitch aimed at a top-producing sales agent reads differently than one aimed at a managing broker. Segmenting before you send is the difference between a campaign that converts and one that gets ignored.

Why Citrus County, Florida Agent Data Matters

Citrus County covers a concentrated Gulf Coast market that includes Inverness, Crystal River, Lecanto, Homosassa, and Beverly Hills. The agents working these communities know their buyers, their inventory, and their preferred vendor relationships personally. A statewide Florida blast dilutes your message across hundreds of markets where your offer may not even apply. Targeting Citrus County specifically means every recipient is a realistic prospect for what you are selling.

With {{AGENT_COUNT}} active agents across the county, the list is large enough to run a meaningful campaign and focused enough to keep your cost per contact low. The data is available at the state, county, city, and zip code level — and no other vendor offers zip-code-level segmentation within Citrus County specifically. That precision lets you prioritize the pockets of agent activity that matter most to your outreach strategy before you ever hit send.
