What triggers can be used for automation?

Triggers are events or conditions that initiate automated email sequences. They come from various data sources.

Subscription events:

New signup → Welcome series
List change → Preference update confirmation
Unsubscribe → Feedback request

Purchase/Transaction events:

Order placed → Order confirmation
Order shipped → Shipping notification
Order delivered → Review request
First purchase → Thank you + onboarding
Repeat purchase → Loyalty acknowledgment

Browsing behavior:

Product viewed → Browse abandonment
Category browsed → Related content
Search performed → Search follow-up
Pricing page visited → Sales outreach

Cart/Checkout actions:

Cart created → Begin cart abandonment timer
Cart abandoned → Recovery sequence
Checkout started but not completed → Checkout abandonment

Engagement triggers:

Email opened/clicked → Send related content
No engagement for X days → Re-engagement campaign
Link clicked → Topic-specific follow-up
Survey completed → Thank you + segmentation

Date-based triggers:

Birthday → Birthday email
Anniversary of signup → Customer anniversary
X days since last purchase → Replenishment reminder
Subscription renewal approaching → Renewal reminder

Custom data triggers:

Field value changes → Relevant communication
Score threshold reached → Sales notification or offer
Segment entered → Segment-specific sequence

Every meaningful customer action or milestone can be a trigger. The question is which triggers warrant automated responses and what those responses should be.
