MCPDeck — Open-Source Cold Email Console

Run cold email from your own inbox without paying per-lead SaaS fees

Problem

Tools like Instantly and Smartlead charge heavily per lead for basic cold email campaign management. One developer got tired of it and built Hedwig, an open-source alternative: emails go from your own inbox, you get open rates and analytics, and an MCP server lets Claude or Codex manage the whole campaign. This exposes a real gap for early teams that want cheap, programmable, self-hosted outreach rather than another expensive SaaS.

Solution

An open-source cold email campaign console that connects Gmail/Outlook inboxes, offers sequence orchestration, open and reply analytics, multi-inbox rotation, and an MCP or API layer so coding agents can create and adjust campaigns directly. The core promise is zero per-lead fees and data staying on your side.

Users

Budget-conscious indie developers, early-stage sales teams, and small agencies that want to run outreach themselves with AI agents.

MVP

OAuth connect Gmail/Outlook inboxes; upload contacts CSV and compose sequence templates; open, click, and reply analytics dashboard; multi-inbox rotation with daily limits; MCP server exposing a minimal toolset to create campaigns, pause, and fetch stats.

Revenue

Open-source core free; hosted subscription for warmup, deliverability monitoring, and team collaboration; enterprise self-hosted license.

Why now

AI agents make campaign creation and tuning automatable, while per-lead pricing from incumbents keeps getting worse for small teams. The open-source plus MCP combination lands exactly on the developer audience willing to self-host.
