About Jeffrey Warren

Jeffrey Earl Warren's professional journey encompasses two distinct phases. After earning his degree from the University of California, Berkeley, he dedicated 15 years to the advertising industry. He held prominent positions, including Copywriter and Vice President/Creative Director at J. Walter Thompson in New York, followed by Senior Vice President at Foote Cone & Belding in San Francisco. During his time in New York, Jeffrey co-authored the fitness book *Mike Spino’s Mind/Body Running Program*, published by Bantam, and contributed op-eds, magazine articles, comedic pieces, and served as a speechwriter.

In 1986, at the invitation of his father, he transitioned to the family real estate business in St. Helena, where he specialized in vineyard and winery properties. As President of James Warren & Son, he later joined Golden Gate Sotheby’s International Realty. His role as a minority owner of Freemark Abbey Winery has deepened his expertise in real estate and the wine industry, making him a trusted resource for both local residents and newcomers looking to establish their families in the Valley.

Jeffrey understands the challenges his clients face, having navigated similar experiences himself. He continues to nurture his passion for writing through a weekly column in the *St. Helena Star* and previously hosted a local radio show on KVON Napa. He resides in St. Helena with his wife, Cynthia, and their three children: Casey, JJ, and Cody.

When businesses need to reach working real estate agents in Sonoma County, a verified agent email list is the fastest way in. Mortgage lenders use it to introduce loan programs directly to agents who can send referrals. Title companies use it to pitch closing services. PropTech companies use it to demo software. Recruiters use it to poach top producers. Insurance providers and continuing education companies rely on it to put offers in front of a captive licensed audience that has ongoing professional obligations and purchasing needs.

This list covers every actively licensed real estate agent operating in Sonoma County, California — {{AGENT_COUNT}} agents total, with {{CELL_COUNT}} cell phone numbers included for campaigns that go beyond email. Whether you are running a cold email sequence, a ringless voicemail drop, or building a custom audience for LinkedIn matched targeting, this data gives you the reach to do it right. Buying a Sonoma County real estate agent email list from a source that actually maintains the data is what separates a campaign that converts from one that bounces into a void.

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

Every record in this list is sourced directly from the California Department of Real Estate licensing database, cross-referenced against active license status, and verified for email deliverability. The list is refreshed with new agents added weekly, scrubbed monthly to remove bad addresses, and completely rebuilt from source data bi-annually. That process is why we back this list with a 96% deliverability guarantee — something no discount data vendor can honestly offer because they are not doing the maintenance work behind it.

Dr Bill has been in the list business since 2005 and has sold over 31,000 lists. That track record matters when you are putting budget behind an outreach campaign. Cheap alternatives recycle stale data and sell the same unverified file to everyone. This list is available at the state, county, city, and zip code level — and no other vendor segments agent data down to individual zip codes within Sonoma County the way we do. That granularity lets you target precisely instead of over-mailing.

How to Use This Sonoma County Agent List

Email outreach is the primary use case, and this list plugs directly into cold-email platforms built for high-volume prospecting. Zap Contact at zapcontact.com is purpose-built for this kind of campaign and works seamlessly with the file format we deliver. You can also use the data for direct mail, SMS, or phone outreach using the included cell numbers, and import the emails into LinkedIn for matched audience ad targeting that reinforces your cold outreach.

The list can be segmented by broker versus individual sales agent, letting you pitch broker-owners differently than rank-and-file agents. A recruiting firm targets those segments with completely different messaging. So does a CE provider versus a mortgage lender. That flexibility makes one list usable across multiple campaigns without buying new data each time.

Why Sonoma County, California Agent Data Matters

Sonoma County covers a wide geographic footprint that includes Santa Rosa, Petaluma, Rohnert Park, Windsor, Healdsburg, Sebastopol, Sonoma, and Cotati. Agents working these markets are distinct from agents in San Francisco or the East Bay, and a statewide blast treats them the same — which wastes budget and dilutes relevance. Local targeting means your message speaks to the market conditions and community that Sonoma County agents actually operate in every day.

With {{AGENT_COUNT}} actively licensed agents in the county carrying verified email addresses, and {{CELL_COUNT}} of them reachable by phone, you have meaningful scale without paying for a statewide file you do not need. Zip-code-level filtering lets a Petaluma title company ignore Santa Rosa agents entirely, or a lender target only the highest-density zip codes first. That kind of precision is only possible when the underlying data is built and maintained the right way — which is exactly what this list delivers.
