As you add more AI tools and teammates, duplicate messages multiply. DeDupe Shield keeps every channel in sync.
Before any message goes out, your AI agent or SDR calls /api/check. Get the full contact history back in under 100ms.
Email, LinkedIn, Slack, phone — every touchpoint is linked to one canonical contact. One lookup covers everything.
REST API for any tool. MCP Server for AI agents. Zapier and Make compatible. Works wherever your outreach lives.
See exactly who contacted a person, when, on which channel, and what was said. Full audit trail for your team.
Your whole team sees the same contact history. No more "I already talked to them" moments after the message is sent.
Your contact history is your competitive advantage. The more you log, the more valuable DeDupe Shield becomes. It's a moat.
Set up in minutes. Works with your existing tools.
Grab your API key from the dashboard. Add it to your AI agents, Zapier flows, or call the REST API directly from any outreach tool.
Every time a message goes out, log it. Channel, sender, note — all stored against the contact. Works automatically when you wire up the API.
Your AI agent calls POST /api/check before composing a message. If the contact was already reached out to, it gets back the full history and can decide what to do.
