About John Sincox

Raised on Galveston Island, this real estate professional has deep roots in the area, with a family history of beach house ownership and personal experience managing multiple properties on the island's west end. Growing up in Clear Lake City has afforded them a comprehensive understanding of both the Clear Lake and Galveston real estate markets.

Their educational background includes attending Clear Lake High School, followed by Texas A&M University, and earning a Master of Science in Finance from the University of Houston. In addition to holding a real estate broker's license, they have maintained a CPA license for several years, further enhancing their financial expertise.

In the Clear Lake area, they specialize in various subdivisions, including Bay Oaks, Pine Brook, Brookwood, Northfork, Clear Lake Forest, Kirby Woods, Bay Forest, and Bay Glen. On Galveston Island, they assist clients with properties in sought-after locations such as Pirates Beach, Pirates Cove, Lafitte's Cove, Isla del Sol, Sea Isle, Beachside Village, Beachtown, Sandhill Shores, Kahala Estates, Kahala Beach, and Spanish Grant.

Their experience extends to working with buyers and sellers of condominiums in both Galveston Island and Clear Lake City, with notable properties including Pointe West, Palisade Palms, Ocean Grove, and Endeavor.

If you need to reach working real estate agents in Galveston County, Texas, this list was built for you. Mortgage lenders prospecting for referral partners, title companies building closing pipelines, PropTech platforms launching in coastal Texas markets, CE providers scheduling license renewal courses, insurance agents selling E&O or homeowners policies, and recruiters targeting experienced producers all rely on verified agent contact data to drive outreach that actually converts. Cold calling a list of stale emails or hunting LinkedIn by hand wastes budget and time — a targeted, current agent list puts your message in front of the right professionals immediately.

When you buy Galveston County real estate agent email list data from Dr Bill, you get {{AGENT_COUNT}} actively licensed agents with verified email addresses, plus {{CELL_COUNT}} agents who also include a cell phone number. Whether you are running an email drip sequence, a direct mail drop, or a phone-based outreach campaign, every record in this list represents a real, working licensee — not an expired agent, a duplicate, or a bad address pulled from a scraped website.

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

Dr Bill has been in the real estate data business since 2005 and has sold over 31,000 lists to B2B marketers, lenders, recruiters, and vendors across the country. Every record is sourced directly from the Texas Real Estate Commission licensing database, which means you are only getting agents who are actively licensed and legally practicing. The list is cleaned monthly, new emails are added weekly, and the entire database is completely refreshed bi-annually — so you are never paying for data that has been sitting on a hard drive since last year.

Cheap list vendors offer no guarantees and often recycle the same outdated spreadsheets. Dr Bill backs every list with a 96% deliverability guarantee. If your bounce rate exceeds 4%, you receive replacement records — no arguments, no runaround. For your sending infrastructure, this data is optimized for cold-email platforms including Zap Contact at zapcontact.com, which handles deliverability, sequencing, and compliance in one place.

How to Use This Galveston County Agent List

Email outreach is the fastest path to ROI with this data. Load the list into your cold-email platform, segment by broker versus sales agent to tailor your message by seniority and role, and launch sequences that speak directly to each agent's business needs. The cell phone numbers also make this list ideal for SMS campaigns, ringless voicemail drops, or a direct-dial calling blitz run by your inside sales team.

Beyond digital outreach, you can use this list for direct mail postcards, LinkedIn audience matching to build a custom ad audience of Galveston County agents, or CRM enrichment to fill gaps in contacts you already own. No other vendor segments this data at the zip code level within Galveston County — meaning you can target Friendswood separately from Jamaica Beach if your offer is hyper-local.

Why Galveston County, Texas Agent Data Matters

Galveston County covers a diverse mix of markets including Galveston Island, League City, Texas City, Dickinson, Friendswood, Clear Lake Shores, and Jamaica Beach. Agents working these submarkets serve entirely different buyer profiles — from beachfront vacation property clients to suburban families relocating from Houston. With {{AGENT_COUNT}} verified licensees operating across this county, you have enough volume to run statistically meaningful campaigns while keeping targeting tight enough to be relevant.

Blasting a statewide Texas agent list to reach Galveston County producers means paying for hundreds of thousands of records you will never use and competing for attention in an inbox flooded with generic mass marketing. County-level targeting lets you craft messaging that references the local market by name, which increases open rates, reply rates, and ultimately your return on list investment.
