Why is my click rate showing zero in an email sequence?

Context

When running email sequences with external links (links that direct to domains outside your website), you may notice that the click rate tracking shows zero clicks, even when emails have good open rates and engagement.

Answer

Unify's click tracking functionality works for links that direct to domains where the Unify tracking tag is installed. This includes your main website as well as any external domains you control (such as documentation sites on platforms like Mintlify) where you can install the tracking tag. Links to third-party domains where you cannot install the Unify tracking tag (such as scheduling tools, social media, or other platforms) will not be tracked in your click rate metrics.

To track clicks in your email sequences:

  1. Ensure the links in your email sequence direct to pages on domains where the Unify tracking tag is installed (your website or controlled external domains like documentation sites)

  2. Verify that the Unify tracking tag is properly installed on your website by checking for a green checkmark in your Unify dashboard integrations page. If the tag isn’t showing as installed or you want to verify it’s loading correctly, open your browser’s DevTools Console on your website and run window.unify && window.unify.page() — if window.unify is undefined, the tag isn’t loading on that domain.

  3. If you need to use external links, be aware that clicks on these links will not be reflected in your sequence analytics

Note: If you need to track clicks to external links, consider creating a landing page on your website that redirects to the external destination. This way, the click to your domain will be tracked before redirecting to the external site.

Troubleshooting Tag Installation: If the Unify tag isn’t loading (console shows undefined), check if your site uses a Content Security Policy (CSP). You’ll need to add these directives to your CSP configuration: script-src https://tag.unifyintent.com and connect-src https://api.unifyintent.com. These can be added via HTTP response headers or a <meta http-equiv="Content-Security-Policy" ...> tag in your HTML. After updating your CSP, hard refresh the page and recheck the console.

Understanding Click and Open Tracking Independence

While the published article covers why click rates might show zero due to external links, it's important to understand that click tracking and open tracking work independently in email sequences.

You may see clicks recorded even when no email opens are shown, as email opens rely on tracking pixels that can be blocked by email clients or privacy settings, while clicks are tracked directly when users interact with links to your domain.

  • A user can click a link without an "open" being recorded if their email client blocks tracking pixels

  • Click data may be more reliable than open data for measuring actual engagement

  • Your click-to-open ratio calculations may be affected by this tracking discrepancy

When analyzing your email sequence performance, consider that clicks represent more definitive user engagement than opens, since clicks require direct user action while opens can be blocked by privacy features in modern email clients.
