Newsletter Automation

A complete newsletter management system built on n8n and Google Sheets. Handles subscriber signups with double opt-in, automated welcome drip emails, broadcast sending, and daily analytics reports.

Problem

Running a newsletter manually means juggling signup forms, confirmation emails, welcome sequences, and broadcast sends across multiple tools. Most newsletter platforms charge per subscriber, and you lose control of your data.

This system gives you a free, self-hosted newsletter pipeline using n8n and Google Sheets.

What It Does

1. Double Opt-In Signup — Webhook receives signups, validates email, sends confirmation link, stores in Sheets
2. Welcome Drip Sequence — Automatically sends Day 0 (welcome), Day 3 (tips), Day 7 (resources) emails
3. Broadcast Sender — API-triggered broadcast to all confirmed subscribers with unsubscribe links
4. Daily Analytics — Subscriber counts, growth metrics, confirmation rates, top sources
