About Ellen Valentgas

Ellen Valentgas, recognized as the 2017 Cape Cod Agent of the Year by Sotheby’s International Realty, has called Osterville village home for over ten years. Her commitment to the community is evident through her active participation on the Steering Committee for the Osterville Business Professional Association and her role as a Trustee of the Osterville Village Library, where she plays a key part in organizing events that highlight the village's distinct character.

Before relocating to Cape Cod, Ellen spent more than 20 years operating a landscape and design business on Nantucket. This experience honed her meticulous attention to detail and deepened her understanding of client needs.

Currently ranked among the top 2% of agents on Cape Cod, Ellen seamlessly integrates her design expertise with her enthusiasm for residential properties. Her renovation and construction projects throughout the region showcase her ability to transform spaces, exemplified by her award-winning design of a property on Oyster Way in Oyster Harbors. Ellen's keen sense of natural flow, both indoors and outdoors, culminated in the creation of this remarkable home. She leverages her design and construction experience to assist clients with renovation projects post-purchase, providing valuable insights and connections to reputable tradespeople, which is essential for her luxury clientele seeking to personalize their homes.

Ellen is affiliated with the Cape Cod & Islands, Massachusetts, and National Associations of Realtors, and holds the Resort and Second Home Property Specialist Designation. In 2016, she was honored as one of the Top 20 Agents on Cape Cod by Boston Top 20 and achieved second place in overall sales production at her Osterville office. Additionally, she leads her office in vacation rental representation. Whether her clients are buying, selling, renting, or renovating, Ellen’s vision, experience, and unique perspective ensure tailored and successful outcomes.

If you need to reach working real estate agents in Barnstable County, Massachusetts, this list was built for you. Mortgage lenders prospecting for referral partners, title companies expanding their closing networks, PropTech platforms pitching new tools, insurance providers, continuing education companies, and recruiters all use this data to open doors with the agents who are actively closing deals on Cape Cod right now.

Unlike broad statewide campaigns that waste budget on agents outside your service area, this list puts you in front of the specific professionals you need. Whether you are launching an email sequence, building a phone outreach campaign, or matching contacts on LinkedIn, having clean, county-level agent data is the difference between noise and results.

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

Every record in this list is sourced directly from the Massachusetts state real estate licensing board, so you are reaching agents who are verified, active, and licensed — not scraped from outdated directories or aggregated from stale third-party feeds. The list is cleaned monthly, new emails are added weekly, and the entire database is completely refreshed bi-annually. That discipline is why we back every list with a 96% deliverability guarantee, something cheap alternatives simply cannot offer.

Dr Bill has been in the list business since 2005 and has sold over 31,000 lists to marketers, lenders, vendors, and recruiters across every industry that works with real estate professionals. When you buy Barnstable County real estate agent email list data here, you get {{AGENT_COUNT}} actively licensed agents with verified email addresses, plus {{CELL_COUNT}} agents who also have cell phone numbers on file for SMS or direct dial campaigns.

How to Use This Barnstable County Agent List

Email outreach is the most common use case, and this list is formatted to drop directly into cold-email platforms. We specifically recommend Zap Contact at zapcontact.com, which is built for exactly this kind of B2B agent outreach and handles list uploads, sequencing, and deliverability tracking cleanly. You can also use the data for direct mail pieces, ringless voicemail drops, or cold calling campaigns using the included cell phone numbers.

For sharper targeting, the list lets you segment by broker versus sales agent, so a recruiter hunting for experienced producers can filter differently than a CE provider marketing license renewal courses. No other vendor offers this list segmented down to the zip code level within Barnstable County, giving you precision that statewide or even county-wide blasts cannot match.

Why Barnstable County, Massachusetts Agent Data Matters

Barnstable County covers the entire Cape Cod peninsula, including active real estate markets in Barnstable, Hyannis, Falmouth, Sandwich, Dennis, Yarmouth, Brewster, Harwich, Chatham, Orleans, Eastham, Wellfleet, Truro, and Provincetown. Each of these communities has its own agent ecosystem, and targeting them by city or zip code lets you speak directly to the local market rather than broadcasting to agents two counties away.

With {{AGENT_COUNT}} licensed agents in the county, the Barnstable market is dense enough to support a serious outreach campaign but focused enough that every contact counts. Local targeting here is not just convenient — it is a strategic advantage over vendors pushing statewide blasts that dilute your message and your budget.
