Case Study: King County, WA achieves higher ballot cure rates and voter turnout with Granicus

How King County, WA keeps voters aware of mail-in ballots and encourages voting participation

King County Elections (KCE) manages elections for roughly 1.4 million registered voters across 192 jurisdictions and wanted to increase transparency and voter awareness around Washington’s vote-by-mail process. With vote-by-mail under greater public scrutiny, KCE needed a reliable way to notify voters about their ballot status and help ensure ballots were counted accurately and equitably across a diverse population.

KCE implemented opt-in text and email ballot-status alerts via the county “My Voter Information” portal, using govDelivery and a custom GXG API to send targeted, multilingual updates. The program produced strong results: alerted voters had a much higher cure rate (over 80% of challenged, alerted voters cured their ballots versus 48% otherwise, about a 67% improvement) and opt-in voters showed markedly higher turnout (65% vs 34% overall in a 2023 special election, about a 91% lift); KCE plans to expand messaging and add Russian and Somali alerts.
