On the journey canvas, nested journeys act like containers for a set of flow steps — like a journey within a journey. Users can configure unique exit criteria for each nested journey. As contacts progress through the flow steps in a nested journey, they are evaluated for the nested journey's exit criteria. Once a contact meets the nested journey's exit criteria, the contact exits the nested journey, skips over the remaining flow steps in the nested journey, and continues on the defined path. ## Common Use Cases ### Behavior-based Onboarding In onboarding journeys, nested journeys can be used to send relevant, behavior-based communications. for each onboarding milestone. The exit criteria for each nested journey are milestones along the onboarding and adoption path. When a contact completes a milestone action, they are moved to communications about the next milestone, in the next nested journey. ### Single-canvas Event Execution In event journeys, nested journeys can be used to remove event registrations from a stream of promotion emails, and route them to a delay flow step where they wait for a reminder about the upcoming event. ### Multi-email Nudges In a journey encouraging a specific behavior (like feature adoption, or reactivation), a nested journey can listen for contacts who complete the desired action, remove those contacts from the communications stream, and re-route those contacts to a more relevant communication, given their behavior. In this reactivation journey, emails 1-3 are wrapped in a nested journey. They encourage users to log back into the product. The nested journey exit criteria is a user logging in. When a contact completes this desired action, they exit the flow of emails 1-3, and jump to the final email in the series, where a CSM offers a calendar link to meet. ## Using Nested Journeys From the **Flow step** panel, select **Nested journey**. Flow step panel with the Nested journey option Add flow steps to the nested journey container. Nested journey container on the canvas with flow steps added inside Nested journey exit criteria can be configured once: 1. The nested journey has at least one flow step inside of it 2. A destination flow step has been created (Where will contacts who meet the exit criteria flow?) Exit criteria configuration for a nested journey named Milestone 1 Hover over **Nested journey** in the top left of the nested journey to edit the name of the container. In the screenshot above, the name of this nested journey is **Milestone 1**. ## Exit Criteria Evaluation Contacts are evaluated for exit criteria when they move from one flow step to the next. If a contact enters a 2-day delay step and immediately qualifies for the exit criteria, they will complete the delay step before the exit criteria takes effect. This means they will wait 2 days, and then get removed from the nested journey and follow the path configured by the user.
