Understand Hubspot Sales Email Open and Click Tracking

Hubspot tracking for sales emails helps you see who opens and clicks your messages so you can prioritize outreach and measure engagement. This guide explains how the tracking works, why metrics may look different than expected, and what you can do to improve data accuracy.

How Hubspot Email Open Tracking Works

When you send a tracked sales email, the system automatically inserts a tiny invisible image into the message.

• Each invisible image is unique to the email and recipient.
• When the recipient’s email client loads images, the image is requested from the tracking server.
• That image request is recorded as an email open.

This mechanism allows Hubspot to display open notifications and log open events on contact timelines. However, it also means open data depends heavily on the recipient’s email settings and email client behavior.

What Can Affect Hubspot Open Tracking

Several technical and behavioral factors can change how opens are counted or displayed.

Image loading settings in email clients

Because tracking relies on the invisible image, image settings matter:

• If images are blocked by default, opens may not be recorded even when the email is read.
• If images are always allowed, opens are more likely to be tracked accurately.
• If a security tool strips images, opens might never be logged.

These behaviors are controlled by the recipient and their IT environment, not by Hubspot configuration.

Multiple opens from forwarding or preview panes

Sometimes an email will show several opens from what appears to be a single recipient. This can happen when:

• The email is forwarded internally and multiple people read it.
• The same recipient re-opens the email many times.
• An email client displays the message in a preview pane repeatedly.

Each time the tracking image is loaded, Hubspot records another open event, which can increase the total count.

Privacy features and security gateways

Modern privacy features and security tools can change how open data appears:

• Some tools pre-load images to scan emails for threats.
• This pre-loading can generate open events even if a person never actually reads the email.
• Anonymous or proxy servers used by these tools can cause opens to appear from unexpected IP addresses or locations.

Because these events still request the tracking image, they are counted as opens by Hubspot.

How Hubspot Email Click Tracking Works

Click tracking is handled differently and is generally more reliable than open tracking.

• Each link in a tracked email is rewritten to a tracking URL.
• When the recipient clicks a link, they are briefly directed through that tracking URL.
• The system logs the click and then forwards the user to the final destination.

This method lets Hubspot record when a click happens and associate it with the correct email and contact.

Why clicks may not be recorded

There are several reasons a click might not appear in your tracking data:

• The email was sent without click tracking enabled.
• A security tool replaced original links with its own secure redirects.
• The recipient copied and pasted the final URL instead of clicking the tracked link.
• The click was made in a plain-text version of the email without tracking links.

If any of these occur, the tracking server might never be called, so Hubspot cannot log the click event.

Differences Between Hubspot Metrics and Other Tools

It is common to see different open and click counts when comparing Hubspot with another email or analytics platform.

Variations in tracking methods

Each system may use different rules for tracking:

• One tool may filter out suspected bot activity, while another records it.
• Some platforms may use alternate tracking parameters or cookies.
• Time windows for counting opens and clicks can differ.

These variations mean numbers across tools are rarely identical even when emails are sent to the same audience.

Timing and synchronization issues

Metrics can also diverge because of timing:

• Reports may refresh at different intervals.
• Delayed opens and clicks may appear later in one system than another.
• Caching and network latency can affect when events are recorded.

As a result, Hubspot reporting should be evaluated in context rather than matched one-to-one against other platforms.

How to Troubleshoot Hubspot Email Tracking

If you suspect your open or click numbers are not reflecting real engagement, use these steps to diagnose the situation.

1. Confirm that tracking is enabled

1. Check that email tracking is turned on in your extension or connected inbox settings.
2. Ensure you are sending tracked sales emails from a connected account.
3. Send a test message to your own inbox and verify that an open is recorded.

If a test email does not generate any tracking events, review your sending method and connection settings in Hubspot.

2. Review recipient environment and behavior

1. Ask key recipients whether images are allowed in their email client.
2. Verify if their company uses aggressive security scanning tools.
3. Check if your emails are frequently forwarded within their organization.

These factors can all change how open and click data appears, even though Hubspot tracking is functioning correctly.

3. Compare click data with on-site analytics

1. Identify a campaign where email links point to your website.
2. Note the number of tracked clicks on those links.
3. Compare with sessions or page views from that campaign in your web analytics.

Click numbers that move in the same direction as website traffic trends usually indicate that Hubspot tracking is working as intended, even if the totals are not identical.

4. Test with different email clients

1. Send test emails to accounts on multiple providers (for example, Gmail, Outlook, and a corporate inbox).
2. Open the emails and click links from each account.
3. Check the contact records and activity feed for each address.

This method can help you isolate whether tracking discrepancies are tied to one specific email client or environment.

Best Practices to Improve Hubspot Tracking Accuracy

While no tracking setup is perfect, you can take steps to get cleaner engagement data.

• Encourage important recipients to add you to their safe sender list so images are more likely to load.
• Keep links clearly labeled to encourage real human clicks rather than copy-and-paste behavior.
• Use consistent sending domains and authentication to reduce security scanning issues.
• Monitor unusual spikes in opens or clicks that may indicate bot or gateway activity.

By combining these practices with an understanding of how Hubspot collects data, you can interpret your reports more confidently.
