How could you use an If / Else branch in a customer journey to build a strong post-purchase campaign?

An If/Else branch in a customer journey allows you to segment contacts based on specific criteria. In a post-purchase campaign, you can use this to check if a customer who bought one product subsequently purchased a related, "paired" product. If they did, they might receive a thank-you or loyalty message. If not, they could be targeted with an upsell or cross-sell campaign for the paired item, enhancing the post-purchase experience and driving further sales. The option about a pop-up is incorrect because customer journeys orchestrate automated communications and actions, not real-time website pop-ups. The option about funneling contacts to a new journey based on their purchase decision is too vague; while an If/Else branch can lead to different paths, the "paired product" scenario is a more specific and effective application for a strong post-purchase campaign.
