About John Kost

The Kost family has been synonymous with Willow Glen for over twenty years, thanks to John Kost's dedication to the real estate market. With a deep appreciation for historic homes, John has successfully facilitated the sale of more than 600 properties in Willow Glen, accumulating over $400 million in sales. His extensive knowledge and experience in the industry enable him to provide exceptional service to his clients, fostering lasting relationships.

A graduate of Live Oak High School, John obtained his real estate license in 1996. He played a pivotal role in establishing the Willow Glen agents tour group, which he led from 2000 to 2006. Following this, he served as the general sales manager at Remax from 2006 to 2007 and continued his career at Intero Real Estate until 2015. Additionally, he holds the designation of Senior Real Estate Specialist (SRES).

John's personal life is equally fulfilling; he is partnered with Keli Hemingway, his high school sweetheart. After dating for three years in the 1980s, they reconnected after a 25-year hiatus. Together, they have one daughter, Annidine, who is in her twenties.

Currently residing in downtown Willow Glen, John is an avid sports enthusiast and a proud season ticket holder for the San Francisco Giants. He also supports the San Francisco 49ers and the Golden State Warriors. A passion for classic cars further enriches his life, as he owns and races a vintage 1963 Ford Falcon drag car.

John specializes in real estate throughout Willow Glen, Morgan Hill, and South San Jose, where he continues to make a significant impact in the community.

If you need to reach working real estate agents in Canyon County, Idaho, this list was built for you. Mortgage lenders, title companies, PropTech platforms, and insurance providers all use this data to put their offers directly in front of licensed professionals who are actively closing deals. Continuing education providers and real estate recruiters rely on it to fill courses and attract experienced agents without wasting budget on untargeted campaigns.

When you buy a Canyon County real estate agent email list, you are getting {{AGENT_COUNT}} actively licensed agents with verified email addresses, plus {{CELL_COUNT}} agents who also have cell phone numbers on file. That combination gives you options — email sequences through cold-email platforms like Zap Contact (zapcontact.com), phone outreach, or both running in parallel to maximize your response rates.

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

Every record in this list is sourced directly from the Idaho Real Estate Commission, which means you are starting from verified, official licensing data — not scraped websites or outdated directories. New emails are added weekly, the full list is cleaned monthly, and the entire database is refreshed bi-annually. That discipline is why Dr Bill guarantees 96% deliverability, a standard that cheap list brokers simply cannot meet because they do not invest in ongoing maintenance.

Dr Bill has been in this business since 2005 and has sold over 31,000 lists across the country. That track record matters when you are choosing between a proven data partner and an unknown vendor selling stale exports. Generic alternatives cut corners on verification and leave you paying for bounced emails and burned sender domains. This list does not do that.

How to Use This Canyon County Agent List

The most direct use is an email campaign built inside a cold-email platform like Zap Contact, where you can automate sequences, track opens, and follow up with agents who engage. The cell phone data opens the door to SMS outreach and direct calls, giving you a multi-touch approach without needing to build your own prospecting infrastructure from scratch. Direct mail campaigns using the physical address data are another proven channel for standing out in a crowded inbox environment.

Segmenting by broker versus sales agent lets you tailor your message precisely. A recruiting firm pitching a new brokerage model speaks differently to a managing broker than to an individual agent. LinkedIn matching using the name and brokerage fields adds a fourth touchpoint that warms cold contacts before your first email ever lands.

Why Canyon County, Idaho Agent Data Matters

Canyon County is home to fast-growing cities including Nampa, Caldwell, Middleton, Notus, and Parma, each with its own active agent community. With {{AGENT_COUNT}} licensed agents operating across this county, there is enough critical mass to justify a dedicated, county-level campaign rather than diluting your message across a statewide Idaho list where most recipients have no connection to your market focus.

No other vendor offers this data segmented down to the zip code level within Canyon County — a capability that lets you isolate agents working specific neighborhoods or growth corridors. That precision means lower cost per response and higher relevance for every contact you make.
