The Flow Trigger A flow can be triggered when someone takes an action that is tracked by Klaviyo, or when someone is added to a list or segment. When a user meets the trigger you set, they will enter your flow at that time. Here is a list of the three different types of triggers and when they might be used: Subscribes to a list: If you have a sign up form(s)

When building a flow, you may have a particular email that you would only like to go to specific recipients. To accomplish this, you can add an additional filter to a single email within a flow. After the appropriate recipients receive this email, they will continue on the same path as all other recipients who trigger the flow.

Learn how to create a copy of a flow in order to create a new version with a different trigger. A copy of the original flow must be created because once you have set the trigger for a flow, you cannot change it. Trigger filters, profile filters, additional email filters, and dynamic content in emails are all reliant on the specific trigger you set for a flow

Learn how to create a segment- or list-triggered flow and about their re-entry setting.

Learn how to use the flow trigger setup preview tool to ensure your flow is set up as you intended. This will help you understand how your flow is going to behave based on the trigger and profile filters you've added.

Learn how to test your flow after you have configured the trigger, filters, and messages. You may want to test the first few messages to make sure they look exactly right, especially if the email or SMS contains dynamic variables. There are two types of tests you can run:

Learn more about Klaviyo filters which can be used to further narrow triggers or actions in flows. For example, if a flow triggers when someone places an order, a trigger filter could be added to limit this to specific product types. Trigger filters are evaluated alongside the trigger itself to only let certain people into a flow.
