About Letterdrop

Letterdrop helps sales teams scale their best reps by turning their messaging and timing into signals and playbooks that can run on auto-pilot. It monitors competitor activity, social conversations, and job changes to identify high-intent leads. With an API and webhooks, Letterdrop integrates with tools like Pipedream and Clay to push these signals into outbound workflows, allowing AI agents to act on real-time buyer intent.
