Political Direct Mail for Martinez campaigns means targeted USPS mail drops to high-propensity voters using the current county file — sized to the Contra Costa County voter universe rather than a national template. Martinez has roughly 38,000 residents and 24,000 registered voters, which puts most local races inside a small-universe playbook where political direct mail is decisive. As the Contra Costa County seat, Martinez has an outsized civic awareness for its size. The city's refinery heritage and waterfront location create campaigns focused on economic transition, environmental stewardship, and preserving the historic downtown. Our political direct mail program supports Martinez candidates running for Martinez City Council (5 members) and Martinez Unified School District, plus county and ballot-measure efforts in Contra Costa County.
