💬 Gmail campaign sender: Bulk-send emails and follow up automatically if no reply
⚡ 57,867 views · 💬 Lead Nurturing & AI Sales Agents
Description
This workflow allows you to send multi-step email campaigns using n8n, Gmail and Google Sheets.
You define a sequence of emails, and a list of email addresses to send them to. The first email is sent to everyone, but the later emails in the sequence are only sent if no-one has replied to the thread yet.
This means you only need to worry about replying to people who respond to your email, not chasing people who don’t.
Requirements
- A list of emails in a Google sheet. You can define extra info that will be available to your email templates (e.g. name, company, etc.)

- A sequence of emails to send, plus how long to wait to send each one, e.g.
- On day 0: “Hi, {name} — nice to meet you at the conference. Was wondering whether {company} would be interested in a quick call about X?”
- On day 3: “Hi, {name}, just wanted to check in on this. Let me know if there’s any interest!”
- On day 7: “{name}, just wanted to give this one last try”
- A Gmail account (although you could also swap out that part for any other email service)
How it works
When sending the emails, n8n inserts a hidden attribute in each one that tags it as being part of the email campaign. It then regularly looks through the email threads with that tag and checks whether:
- No-one has replied yet
- It’s time to send the next message
The workflow doesn’t send emails on weekends.
Notes
- This workflow is not intended for spam! Please use responsibly
- You can use this workflow for multiple different campaigns by making copies of the workflow and changing the sequence / Google Sheet that it uses
