What this template does

This workflow runs behavior-driven email sequences without a dedicated marketing automation platform. When a user submits a form or enters a segment, n8n picks the right sequence, sends the first email, tracks opens and clicks, and branches the follow-ups based on engagement. Subject lines and send times are A/B tested, and the winner rolls out to the rest of the audience.

It gives you the core of a drip campaign engine (segmentation, timed sends, engagement branching, testing) built on tools you already pay for.

How it works

The trigger is a user submitting a form or entering a segment. The flow:

Determines the user’s segment based on behavior.
Selects the email sequence for that segment.
Sends the Day 0 welcome email.
Waits 24 hours.
Tracks email opens and clicks.
Sends a segment-specific follow-up.
Moves to the next step based on engagement, continuing through a 7-day sequence.

A typical sequence: Day 0 welcome, Day 1 product demo video, Day 3 case study by segment, Day 5 pricing and trial CTA, Day 7 final offer or re-engagement.

Setup steps

Create a Mailchimp audience, add the API key to n8n, and build your email templates.
Configure triggers: a webhook for form submissions, plus Google Analytics event tracking and link click and open monitoring.
Define segments, for example high engagement (opens over 50 percent), low engagement (opens under 20 percent), and new subscribers.
Build the day-by-day sequence with wait nodes between sends.
Set up A/B testing: subject line variants, split-test send times, track engagement, and switch the winner to the remaining audience.
Add Slack alerts for high engagement, log results to Google Sheets, and adjust the sequence based on performance.

When to use it

Reach for this on onboarding sequences for new users, abandoned cart recovery, product launch campaigns, re-engagement campaigns, and sales enablement sequences. It is a strong fit when you want behavior-based branching but do not want to pay for a heavyweight marketing suite.
