Klaviyo offers 6 different types of flow triggers to automate your email and SMS campaigns. Here's what you can use:

Flow Trigger Types

1. Added to List

• Triggers when someone joins a specific list
• Perfect for welcome series when people sign up via forms or subscribe pages
• Example: Send a welcome email immediately, then 2-3 follow-up emails spaced days apart

2. Added to Segment

• Triggers when someone meets segment conditions
• Useful when you want multiple actions to trigger the same flow
• Segments grow/shrink dynamically as people meet or leave conditions

3. Metric (Event-Based)

• Triggers when someone takes a tracked action
• Works with any integration event or API-created events
• Examples: Started Checkout, Placed Order, filled out a form
• Note: Performance metrics like Opened Email and Clicked Email cannot be used as flow triggers

4. Date Property

• Triggers on specific dates or before certain dates
• Can recur monthly or yearly
• Perfect for birthdays, anniversaries, or time-sensitive campaigns
• Works with date properties on profiles or custom objects

5. Price Drop

• Triggers when viewed or abandoned cart items drop in price
• Can be set by dollar amount ($10) or percentage (20%)
• Great for re-engaging potential customers

6. Low Inventory

• Triggers when viewed or abandoned items are running low in stock
• Can specify thresholds by product variant or total product stock
