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.
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
The sender starts with a destination URL
The intended destination may be a product page, article, account page or any other web address.
- 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
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
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.
What link tracking can record
| Signal | Typical source | Important limitation |
|---|---|---|
| Which link was clicked | The tracking URL identifies the campaign or link | A forwarded email can confuse attribution if the link remains tied to the original recipient |
| Click time | The tracking server timestamps the request | Security scanners can sometimes visit links automatically |
| Network metadata | The browser request reaches the tracking server | VPNs, proxies and corporate gateways can change the visible IP |
| Campaign attribution | Identifiers or parameters associate the click with a message | The tracking system's attribution model can be broader than what the destination site sees |
| Destination visit | The redirect reaches the final page | A click does not prove a purchase, signup or other downstream action |
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.
