Variations

The following metrics are tracked for each variation:

• Clicks

The default conversion metric for most ecommerce integrations is Placed Order. If you use this metric, the card will show the placed order rate and the number of recipients who placed an order.

When you hover your cursor over each variation, you will see the option to preview the variation as well as save it as a template.
