Hedwig is a free, open-source, self-hostable alternative to cold email platforms like Instantly and Smartlead. It sends sequences through your own mailboxes at a human pace, stops on replies, labels responses, and lets Claude Code or Codex control and analyze campaigns via MCP. The combination of MCP-driven agent control, BYO-mailbox sending, and reply classification is a pragmatic and interesting take on the B2B outreach tooling space.

Target audience: sales and marketing teams, founders, backend devs, growth engineers
