Hey @Jorge,
When UTM tracking is enabled, they would be applied to all links in your email. Klaviyo doesn’t segregate some links from having UTM parameters applied and others not.
Keep in mind that UTMs are only applied and trackable in Live email sends. If you were previewing the email, you’ll want to ensure you are sending yourself a preview and not viewing within the interface. Although these UTMS would be applied with a test send, they would not be trackable via Google Analytics.
As mentioned prior, in the event that you are sending yourself a test email but not seeing UTMs applied to certain links, this may indicate that your website is either displaying a vanity link or something causing the website to refresh and loading the same URL but stripped of the UTM parameters. I’ve seen this occur if your website is built to recognize the geoIP location of a visitor and redirect them to their country specific website.
Since the Community forum is a space for Klaviyo Customers, partners and other users to network and learn from one another, if you were looking for more direct assistance into what could potentially be causing your UTM parameters to not apply to select links for your specific email and website, I would suggest reaching out to our helpful Support Team who can investigate further.
