In the world of digital marketing, email drip campaigns are a powerful way to nurture leads, onboard customers, and boost conversions. But manually sending these emails is time-consuming and prone to error. That’s where n8n comes in—a no-code automation platform that lets you build personalized email flows using tools like Google Sheets.
In this blog, you’ll learn step-by-step how to automate a complete email drip campaign in n8n using Google Sheets as your contact database. No coding. No expensive tools. Just smart automation.

An email drip campaign is a series of automated emails sent to contacts over a specific timeline. It’s called a “drip” because the messages are sent out slowly, like water dripping from a faucet, based on user behavior, time intervals, or triggers.
Use cases include:
Re-engaging cold subscribers
Onboarding new users
Educating leads
Sending reminders
Promoting products over time

Here’s why n8n + Google Sheets is a powerful combo:
Easily integrates with Gmail, Mailgun, SendGrid, and more
Real-time automation based on spreadsheet updates
No-code builder that anyone can use
Custom email messages with personalized fields
Free to use (especially if self-hosted)
Create a spreadsheet with the following columns:
| Name | Step 1 Sent | Step 2 Sent | Step 3 Sent |
|---|
Fill in a few test rows with email data. Use TRUE/FALSE flags in “Step Sent” columns to track progress.

This will fetch only new contacts for the first email.
{{$json["Name"]}} and {{$json["Email"]}}You can design your message in HTML or plain text.
This prevents re-sending the same email.
Use the Wait node to add a delay (e.g. 2 days) before sending the next drip email.
Repeat this structure for all email steps.
To keep the campaign running daily:
Connect it to the full workflow, so new rows are checked each day
Add a Cron node that triggers every 24 hours

Google Sheets is a great starting point. You can use columns to track each email step sent and update the sheet after every action in N8N.
It depends on your email service (e.g., Gmail allows ~500/day). For higher volume, use services like Mailgun or SendGrid, which are built for email campaigns.
