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.”

Mortgage lenders, title companies, PropTech startups, real estate recruiters, insurance agents, and continuing education providers rely on targeted outreach to connect with active real estate professionals. Our Gillespie County real estate agent email list delivers 194 verified contacts of currently licensed agents, giving you direct access to this specialized market without the guesswork of generic lead generation.

Whether you're launching a new mortgage product, recruiting top performers, or promoting professional services, having accurate agent contact data means the difference between successful campaigns and wasted marketing spend. This curated list eliminates the time-consuming process of manually researching individual agents while ensuring you reach decision-makers who are actively working in today's market.

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

Our agent data comes directly from Texas state licensing boards and undergoes monthly verification processes to maintain 96% deliverability rates. While cheap alternatives flood the market with outdated contact information scraped from public websites, we invest in legitimate sourcing and rigorous quality control to ensure your outreach campaigns actually reach their intended recipients.

Each email address is verified for accuracy and linked to current licensing status, so you're not wasting resources on agents who've left the business or changed brokerages. Our monthly update cycle catches these changes before they impact your campaigns, delivering the data reliability that serious marketers demand when ROI matters.

How to Use This Gillespie County Agent List

Deploy these verified contacts through cold-email platforms like Zap Contact (zapcontact.com), Dr Bill's purpose-built system designed specifically for purchased lists, rather than mainstream platforms like Mailchimp or Constant Contact which prohibit this type of data. You can also leverage the list for direct mail campaigns, phone outreach, or LinkedIn connection strategies to create multi-channel marketing approaches.

The data allows for sophisticated segmentation between broker-owners and sales agents, enabling you to tailor messaging based on role and responsibility. Whether you're targeting decision-makers for B2B partnerships or individual agents for service offerings, having clean contact data with professional details ensures your message reaches the right audience with appropriate positioning.

Why Gillespie County, Texas Agent Data Matters

Gillespie County encompasses Fredericksburg, Stonewall, and surrounding communities where 194 licensed agents serve a distinct market with unique characteristics and client needs. When you buy Gillespie County real estate agent email list data, you're accessing professionals who understand this specific geography rather than casting wide nets across Texas markets that may not align with your service area or expertise.

No other vendor provides Gillespie County agent data at the zip code level, giving you unprecedented targeting precision for hyperlocal campaigns. This granular approach consistently outperforms statewide email blasts because agents respond better to vendors who demonstrate knowledge of their specific market conditions and community dynamics rather than generic statewide messaging.
