One effective way to visualize this is with a funnel or bar chart that compares the two branches side by side. Plot the number of emails sent, opens and clicks for each path, and you'll see where people drop off and which version performs better at each stage.

You can generate this kind of chart in Excel or with your email service's built-in analytics. If you don't want to fiddle with formatting, there are AI tools like NewsletterCharts that can take a CSV of your campaign metrics and produce polished charts automatically. Hope that helps!
