Political Direct Mail for Foster City campaigns means targeted USPS mail drops to high-propensity voters using the current county file — sized to the San Mateo County voter universe rather than a national template. Foster City has roughly 34,000 residents and 20,000 registered voters, which puts most local races inside a small-universe playbook where political direct mail is decisive. Foster City's unique geography — built on reclaimed land below sea level — makes levee improvement the existential campaign issue. Its biotech corridor and Asian American majority population create a policy-oriented electorate focused on infrastructure and schools. Our political direct mail program supports Foster City candidates running for Foster City City Council (5 members) and San Mateo-Foster City School District, plus county and ballot-measure efforts in San Mateo County.
