What types of behaviors can trigger automated emails? (e.g., website visits, link clicks, inactivity)

A wide range of behaviors can trigger automated emails:

Website activity: Page views, product browsing, category exploration, search queries, time on site.

Commerce activity: Adding to cart, removing from cart, wishlist additions, purchases, returns.

Email engagement: Opens, clicks, forwards, replies, unsubscribes.

App activity: Feature usage, in-app purchases, session frequency, achievement completion.

Form interactions: Submissions, partial completions, specific field values.

Account activity: Login frequency, profile updates, preference changes.

Inactivity patterns: Days since last visit, emails without opens, lapsed purchasing.

The specific behaviors worth tracking depend on your business model and the journeys that matter most to your customers.

Any measurable action can potentially trigger an email. The question is which actions signal opportunities for valuable communication.
