Outreach OS connects lead sourcing, AI-assisted research, email drafting, outbound sequencing, mailbox sending and response tracking. Instead of a shared third-party workspace, it runs on infrastructure its operator controls, with their own AI provider and mailbox credentials.
The challenge
Sales outreach is spread across tools, data and workflows.
Outbound sales is more than sending emails. Teams must find the right prospects, research them, personalise each message, manage follow-ups and track replies. When those steps live in different tools, the work becomes repetitive and the team loses control of where prospect data and credentials go.
Manual personalisation
Writing a relevant message for each lead takes research and repeated drafting.
Fragmented execution
Lead management, sequencing, sending and reply tracking need to work as one process.
Limited control
Many teams would rather keep prospect data, credentials and infrastructure in their own hands.
Objectives & strategy
Automate the workflow, keep the operator in control.
- Step 01
Centralise prospect data
Import leads from CSV or discover and enrich them through configured providers, with deduplication rules.
- Step 02
Research before writing
A tool-calling AI agent decides what to look up for each lead, inside step and token budgets.
- Step 03
Personalise the message
Emails drafted by the chosen AI provider from the lead’s context, with retrieval support.
- Step 04
Orchestrate sequences
Campaign steps, send states, mailboxes and follow-ups managed in one place.
- Step 05
Close the loop
Send through SMTP; catch replies through IMAP polling or an inbound webhook, matched to the original message.
- Step 06
Keep it self-hosted
Provider credentials from environment configuration; every service started with Docker Compose.
Outreach is treated as an end-to-end operational workflow, not just an AI email generator.
What we delivered
A self-hosted outbound sales system with AI at its core.
AI-assisted prospect research
A LangGraph-based, tool-calling research workflow decides what to retrieve for each lead, constrained by step and token budgets.
Personalised email generation
A drafting pipeline uses lead context and retrieval; LiteLLM lets it work across supported model providers.
Lead and campaign management
Importing, enrichment, targeting profiles, deduplication, campaign sequences and send states.
Mailbox integration and reply tracking
SMTP for sending; IMAP polling and an inbound webhook for replies, linked to the original send by message headers.
Self-hosted architecture
A Next.js dashboard on a FastAPI back end with PostgreSQL, Redis, background workers and S3-compatible storage, brought together by Docker Compose.
Security and operational controls
Environment-based credentials, encrypted credential storage, row-level security, append-only audit events, suppression lists and data export.
By design the application has no built-in login: it should sit behind an authenticating reverse proxy, never directly on the public internet.
Results & impact
A consolidated workflow with documented capabilities.
- One deployment workflow: Docker Compose coordinates every service.
- Several AI providers, through LiteLLM and environment credentials.
- Two-way email: SMTP sending paired with IMAP and webhook reply capture.
- Bounded AI research, with step and token budgets.
- Safeguards: audit logs, suppression lists, data export and credential protection.
The repository also documents an end-to-end smoke test over real HTTP, SMTP and IMAP in a local test stack.
Outreach OS is in use at Bharat Rise Ranks, a digital marketing agency in Solan.
