Email Outreach Automation

A complete cold email outreach pipeline built on n8n and Google Sheets. Import prospects, run multi-step email sequences, track replies, and get daily campaign reports.

Problem

Cold email outreach requires consistent followup sequences, reply detection, and status tracking across hundreds of prospects. Most tools charge $50-200/month per seat and lock you into their platform.

This system provides a free, self-hosted outreach pipeline with full control over your data and sending.

What It Does

1. Prospect Import — Webhook API to import prospects (single or batch) with validation and deduplication 2. Email Sequences — 4-step automated outreach: initial, follow-up 1 (Day 3), follow-up 2 (Day 7), breakup (Day 14) 3. Reply Tracking — Webhook to mark prospects as replied and notify your team 4. Campaign Reports — Daily metrics: reply rates, bounce rates, step distribution, per-campaign breakdown
