About Shawn Cass

A distinguished real estate professional in South Texas, this agent has consistently ranked among the top in the region's Multiple Listing Service since June 2021 and has been recognized as a leading Realtor in San Patricio County since 2014. With a commitment to excellence, they have received the Top 5 Certificate of Achievement from the San Patricio County Board of Realtors on a monthly basis since 2005. In October 2014, they were honored as the Realtor of the Year by the San Patricio County Economic Development Corporation, acknowledging their contributions across residential, commercial, and land transactions.

This agent's career in real estate began in 1983, followed by the attainment of a Broker’s license shortly thereafter. They hold a Bachelor of Business Administration in Real Estate and Urban Land Development, as well as Risk Management & Insurance and Finance, from The University of Texas at Austin, graduating in 1987. Additionally, they earned a paralegal certification from The University of Texas at Arlington while gaining valuable experience in the mortgage industry. Their expertise is further underscored by a Six Sigma Black Belt certification and a role as an adjunct professor at North Lake College, specializing in Mortgage Loan Applications. They are also a graduate of Leadership Portland, Class II.

As a third-generation real estate broker, they work closely with their sister, Patti Cass-Strain, who is also a broker. Their training was under the guidance of Thomas William Cass, Realtor Emeritus and their father. The family’s legacy in real estate began in 1938 with the establishment of Cass Real Estate by John Michael and May Alice Cass, making it the oldest active business in Portland, Texas.

Mortgage lenders, title companies, PropTech startups, and real estate recruiters consistently buy San Patricio County real estate agent email lists to reach decision-makers who control millions in local transactions. Insurance providers targeting E&O coverage and continuing education companies seeking course enrollments also rely on verified agent contact data to generate qualified leads rather than wasting resources on cold prospects.

This targeted list of 206 actively licensed San Patricio County agents delivers direct access to professionals who influence property transactions daily, making it invaluable for service providers seeking immediate market penetration. Unlike broad demographic lists that include inactive contacts, this database focuses exclusively on current license holders with verified email addresses, ensuring your outreach reaches engaged professionals who can actually purchase your services.

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

Dr Bill sources all agent data directly from Texas state licensing boards and updates the complete database monthly, maintaining 96% deliverability rates that cheap alternatives cannot match. While discount vendors recycle outdated information for months, this premium list undergoes continuous verification to remove inactive licenses, bounced emails, and career changes that render competitor databases worthless.

The 206 verified contacts include complete professional details sourced from official state records, not scraped social media profiles or purchased third-party data that violates compliance standards. Each record undergoes monthly validation against current licensing status, ensuring your campaigns reach active professionals rather than former agents who left the industry years ago but remain on inferior vendor lists.

How to Use This San Patricio County Agent List

Cold email campaigns perform best when deployed through specialized platforms like Zap Contact (zapcontact.com), Dr Bill's purpose-built system designed specifically for purchased lists, since mainstream platforms like Mailchimp and Constant Contact prohibit third-party data. The verified emails also support direct mail campaigns, LinkedIn prospecting, and targeted phone outreach when combined with complete contact records.

Smart marketers segment the 206 contacts by broker versus sales agent roles, focusing higher-value propositions on managing brokers who make purchasing decisions for entire offices. The clean data structure also enables precise geographic targeting within San Patricio County, allowing customized messaging for agents in different cities or zip codes rather than generic county-wide blasts that ignore local market nuances.

Why San Patricio County, Texas Agent Data Matters

San Patricio County encompasses Sinton, Mathis, Portland, Gregory, and other active markets where 206 licensed agents serve diverse client needs from residential sales to commercial development. Local targeting consistently outperforms statewide campaigns because agents respond better to vendors who understand their specific market challenges rather than generic Texas-wide messaging that ignores regional differences.

No other vendor provides San Patricio County agent data segmented by individual zip codes, giving you unprecedented targeting precision within the county's distinct markets. This granular approach enables highly relevant messaging that references specific communities, dramatically improving response rates compared to broad county-level campaigns that treat Portland agents identical to rural Sinton professionals.
