Definition
A behavioural trigger is an event-based condition that automatically initiates an email send. Unlike scheduled broadcast emails sent to an entire list at once, behavioural trigger emails fire in real time when a subscriber performs — or fails to perform — a specific action. This makes them highly relevant and timely, which drives significantly higher engagement rates.
Behavioural triggers are the foundation of marketing automation. Common triggers include website page views, product clicks, cart abandonment, purchase confirmation, birthday dates, and inactivity periods.
Types of Behavioural Triggers
| Trigger Type | Example | Typical Timing |
|---|---|---|
| Page View Trigger | Subscriber views a product page | 1-2 hours after visit |
| Abandoned Cart Trigger | Subscriber adds items but does not check out | 1-24 hours after abandonment |
| Click Trigger | Subscriber clicks a specific link in a campaign | Immediate |
| Inactivity Trigger | Subscriber has not opened emails in 30 days | After inactivity period |
| Behavioural Change Trigger | Subscriber moves from free plan to paid | Immediate |
| Re-engagement Trigger | Subscriber visits website after long absence | Within 24 hours |
Benefits
- Higher relevance: Messages sent in response to real behaviour are naturally more relevant than scheduled broadcasts
- Better timing: Behavioural triggers reach subscribers when they are most engaged and receptive
- Improved metrics: Triggered emails typically achieve 2-3x higher open and click rates compared to broadcast campaigns
- Scalable personalisation: Each trigger email can be dynamically personalised based on the specific behaviour that triggered it
Best Practices
- Define clear triggers: Each trigger should map to a specific, measurable subscriber action
- Set appropriate delays: Some triggers benefit from immediate sends, while others perform better with a short delay
- Include fallback behaviour: Plan what happens if the subscriber does not respond to the trigger email
- Avoid trigger fatigue: Monitor how many triggered emails a subscriber receives and cap frequency where necessary
- Test and iterate: A/B test trigger timing, content, and offers to optimise performance

Frequently Asked Questions
An autoresponder sends a pre-written email sequence triggered by a single event like a signup. A behavioural trigger responds to ongoing subscriber actions and can fire multiple times based on different behaviours throughout the subscriber lifecycle.
Start with the highest-intent triggers: cart abandonment, welcome series, and post-purchase follow-up. Once those are optimised, add browse abandonment, re-engagement, and milestone triggers. Quality matters more than quantity.
