The redirect between the inbox and the destination

How Do Tracked Links in Emails Work?

Tracked email links commonly route a click through a measurement URL before sending you to the final destination. That redirect can record which link was clicked and when.

9 min read

A blue link can look ordinary while its destination is actually a tracking server. When you click, the browser first visits that tracking URL, the server records the event, and then it redirects you to the page you expected. This is a different mechanism from an open-tracking pixel and it can still work even when remote images are blocked.

The click-tracking chain

  1. 1

    The sender starts with a destination URL

    The intended destination may be a product page, article, account page or any other web address.

  2. 2

    The email platform rewrites the link

    Many email systems replace the destination with a tracking URL or add recipient-specific information so the eventual click can be attributed to a campaign or recipient.

  3. 3

    Your browser reaches the tracking server first

    When you click, the tracking endpoint receives a normal web request. It can log the event before responding with a redirect.

  4. 4

    The server forwards you to the final page

    The redirect sends the browser onward. The extra hop is often fast enough that the recipient barely notices it.

Click tracking and open tracking are separate systems

Open tracking often depends on a remote image request. Link tracking depends on an actual or automated request to a URL. That is why blocking images does not automatically make links untracked.

Amazon SES documents that tracked links are replaced with tracking links and that click events can be published for analysis. Salesforce Account Engagement similarly documents rewriting links through tracker subdomains and associating tracked links with individual prospects.

How to inspect a tracked link more safely

  • Preview the link destination without clicking when your mail client supports it.
  • Read the hostname carefully; the visible text in an email can differ from the actual link target.
  • For sensitive account actions, navigate to the service independently instead of relying on an unexpected email link.
  • Treat a click as a new web interaction with its own cookies, logs and privacy rules.

A tracked email link is usually a measured redirect. Understanding the extra hop helps you separate ordinary campaign analytics from the separate question of whether the destination deserves your trust.
