How to track which links are clicked on an email

This is a great discussion on link click analytics in Klaviyo, one of the key challenges is that Klaviyo’s default tracking groups all identical URLs together, so you can see total clicks for a destination but not which specific element (e.g., header vs. footer) triggered those clicks. To differentiate click performance across multiple identical links, a common technical solution is to add unique query parameters or UTM tags (e.g., ?source=header vs. ?source=cta) to make each URL distinct. This allows tracking at the individual link level in analytics tools like GA4 while still being captured by Klaviyo’s click activity reporting. 

For more advanced setups, dedicated click tracking domains can be configured (via DNS CNAME records) so clicks use your own branded domain instead of Klaviyo’s default tracking domain, which helps with deliverability and trust signals. Additionally, Klaviyo’s custom reporting features now allow deeper insights into UTM-tagged link clicks without relying entirely on third-party analytics. Combining these approaches gives marketers much better visibility into click behaviour and allows optimization of email CTAs based on actual interaction patterns.
