Opening vs Follow-Up Messages

While setting visitor flows, each flow must be either an "opening message" or a "Follow-up message". These options can be found in the Message type section, within the visitor flow

Opening messages - Only a single opening message gets triggered for a given page in a single session.

Follow-up messages - For a given page in a given session, any message that needs to be triggered after the "one and only opening message" needs to be set as a Follow-up message.

Follow-up messages become useful while setting flows for visitors based on their in-page activities. Follow-up messages have to be lower in the priority of visitor flows.

Example -

Here are visitor flows set for first-time visitors, repeat visitors, and visitors who have clicked on the outbound tab of the homepage -

This ensures that only the "First-time visitor" or "Repeat Visitor" flow gets triggered at once and the "Outbound Click" flow gets triggered regardless of the opening message.
