Woodpecker.co is a drip email app designed for B2B companies to contact prospective clients directly, sending personalized sales emails and follow-ups automatically from their mailbox. The app helps grow predictable revenue by nurturing inbound leads and detecting replies, allowing users to stop further follow-ups when responses are received. Woodpecker.co also offers shared prospect databases, testing features, and transparent metrics like open and click-through rates to ensure effective drip emails. Users can automate their workflows with Zapier integrations, such as connecting Google Sheets or Pipedrive, and block future follow-up messages when Calendly meetings are set up.
