About Mary Andrea Duperier

Andrea Sissy duPerier, a proud Texan and second-generation REALTOR®, has been immersed in the real estate world from a young age. Inspired by her father, Harold duPerier, she learned the value of determination and the mantra of “making it happen.” Growing up in a family of eight, her nurturing nature earned her the enduring nickname "Sissy." Her diverse experiences span the state, having lived in locations from Beaumont to Alpine.

Sissy holds a bachelor's degree in Elementary and Physical Education from Sul Ross State University, which she utilized as a teacher and coach. Her commitment to education extended to a nine-year tenure on the School Board, where she cherished the impact she made on her students. However, she ultimately discovered that her true passion lies in real estate.

As a devoted mother to two grown children, Caitlynn and Graham, Sissy is deeply committed to helping others. In her free time, she actively volunteers with organizations such as Meals on Wheels, local food pantries, Rotary, and women’s shelters.

Since obtaining her real estate license in 1996, Sissy has dedicated herself to continuous professional development, accumulating over 550 educational hours to remain informed about the latest laws, principles, and ethical standards in the industry. She is a recognized designee and active member of the Graduate Realtor Institute (GRI), reflecting her commitment to enhancing her expertise for the benefit of her clients.

With more than 20 years of experience in real estate, Sissy combines honesty, ethics, determination, and sophistication to provide exceptional service. She is dedicated to simplifying the buying process, whether for a new home or ranch.

Sissy expresses her enthusiasm for real estate by stating, “What excites me most is the rewarding nature of this profession. The thrill of searching for, showing, and ultimately finding the perfect property for my clients is something I will always cherish. I understand that home and ranch purchases can be complex, but I promise to be there with you every step of the way.”

If you're looking to buy a Gillespie County real estate agent email list, you're likely in one of several industries that depend on direct access to licensed agents. Mortgage lenders and title companies use this data to introduce their services to active professionals closing deals in the area. PropTech companies, insurance providers, continuing education vendors, and real estate recruiters all rely on accurate, targeted agent contact data to run campaigns that actually reach decision-makers — not generic inboxes or outdated contacts.

This list gives you immediate access to {{AGENT_COUNT}} actively licensed real estate agents in Gillespie County, Texas, including {{CELL_COUNT}} agents with verified cell phone numbers. Whether you're launching an email sequence, running a phone campaign, or building a direct mail drop, having clean, current contact data is the foundation of any outreach that converts. Reaching the right professionals at the county level eliminates wasted spend and dramatically improves response rates compared to broad statewide lists.

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

Dr Bill has been building and selling real estate agent contact lists since 2005, with over 31,000 lists sold to satisfied clients across every industry that works with agents. Every record is sourced directly from the Texas state real estate licensing board, ensuring you're only reaching agents who are currently licensed and active — not expired or inactive contacts padding a list. Emails are cleaned monthly, new contacts are added weekly, and the entire database is fully refreshed twice a year, all backed by a 96% deliverability guarantee.

Cheap list vendors cut corners by recycling old data and skipping verification. Dr Bill's process is built around accuracy from the ground up. When your email platform — whether you're using a cold-email tool like Zap Contact (zapcontact.com) or another outreach system — hits a deliverability wall, it's almost always a data quality problem. A 96% guaranteed deliverability rate means your sender reputation stays intact and your campaigns actually land in inboxes.

How to Use This Gillespie County Agent List

Email outreach is the most scalable use case, and cold-email platforms make it easy to load your list and launch targeted sequences within hours. You can also use the data for direct mail campaigns, SMS or phone outreach using the included cell numbers, or LinkedIn audience matching to run paid ads directly to the agents on your list. Each of these channels performs better when your underlying data is clean and current.

Segmenting by broker versus individual sales agent lets you tailor your message precisely — brokers respond to different offers than solo agents. No other vendor provides this list segmented down to the zip code level within Gillespie County, giving you a targeting advantage that broader competitors simply cannot match.

Why Gillespie County, Texas Agent Data Matters

Gillespie County includes Fredericksburg, Kerrville Road corridor communities, Harper, and Stonewall — a mix of rural and growing market areas where agents are active but often overlooked by vendors focused only on major metros. With {{AGENT_COUNT}} licensed agents operating across these communities, there is a concentrated and reachable professional audience that responds well to relevant, localized outreach.

Statewide Texas lists bury your message among tens of thousands of agents with no connection to your offer. Targeting Gillespie County specifically means every contact you reach operates in the exact market you care about, making your campaigns more relevant, your response rates higher, and your cost per conversion lower.
