About Martha Knapp

Cape Cod has been an integral part of this agent's life since childhood. Growing up in a Boston suburb, she frequently visited the Cape to connect with family, spending summers camping and enjoying the region's natural beauty. Her fond memories include beach days, campfire stories, and collecting shark teeth at Head of the Meadow Beach in Truro. In 1986, she took a significant step by relocating to the Cape to establish a business in West Dennis, and in 1994, she and her husband settled in Harwich with their two sons, where they have resided ever since.

This agent views Cape Cod as more than just a geographical location; it embodies a distinct lifestyle. Each village possesses its own unique charm, and she believes that a home should reflect the individual character and lifestyle of its owner. The profound beauty of the Cape resonates deeply, making it a true home for those who appreciate its essence.

While she cherishes all seasons on the Cape, autumn stands out as her favorite. The reduced traffic, crisp air, and stunning ocean views create a picturesque backdrop, especially during the cranberry harvest against a clear blue sky.

For clients looking to sell their homes, she offers innovative marketing strategies, staging advice, and comprehensive market analysis to effectively position properties. She is committed to guiding clients through every phase of the selling process, ensuring a smooth closing experience.

For those aspiring to own a home on Cape Cod, she is dedicated to understanding their needs, assisting in property searches, negotiating offers, and providing access to essential resources such as home inspectors, attorneys, and mortgage lenders. Her passion for the Cape, combined with her extensive knowledge of the local market, positions her as a valuable ally in real estate endeavors.

She is an Accredited Buyer’s Representative (ABR) and a Resort and Second Home Property Specialist (RSPS). Her professional affiliations include membership in the Cape Cod and Islands Association of Realtors, the MLSPin Association of Realtors for Boston, the Massachusetts Association of Realtors, and the National Association of Realtors. She has served on the Massachusetts Association of Realtors Board of Directors and various committees within the Cape Cod & Islands Association of Realtors, including Professional Standards and MLS Strategic Planning.

Recognized for her commitment to community service, she received the Massachusetts Association of Realtors "Good Neighbor Award" in 2008 and has been a mentor to new agents. As a Premier Service Certified professional and Kinlin Grover Office Ambassador since 2013, she welcomes the opportunity to assist clients with their real estate needs.

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.
