Email tracking: opens, clicks, replies
Every email from Tesoro automatically receives tracking code. You can see whether the recipient has opened, clicked a link, or replied. No setup needed, always on.
When Is This Relevant?
Section titled “When Is This Relevant?”- You wonder why a lead is no longer responding
- You want to know which prospects are truly interested
- You are preparing the AVG/GDPR section of your privacy statement
What Is Tracked
Section titled “What Is Tracked”| Metric | When | Field |
|---|---|---|
| Opened | Recipient opens email | opened_at |
| Clicked | Recipient clicks a link | clicked_at |
| Replied | Reply received | replied_at |
One timestamp per metric (first time). Plus an activity on the timeline of the associated record.
How It Works
Section titled “How It Works”Two technical mechanisms, automatically applied to every outgoing email.
Tracking Pixel (Open Tracking)
Section titled “Tracking Pixel (Open Tracking)”Invisible 1×1 image at the end of email content, hosted by Tesoro. When opened + images loaded → request to Tesoro server → opened_at recorded.
URL Rewriting (Click Tracking)
Section titled “URL Rewriting (Click Tracking)”All links are rewritten via a Tesoro tracking endpoint. When clicked:
- Click arrives at the endpoint.
- System registers an open and a click (+ URL) on the email.
- Recipient is immediately redirected to the original URL.
Reply Detection
Section titled “Reply Detection”Reply received via your linked inbox → system matches to original email → replied_at + activity email_replied.
Always On: Automatically
Section titled “Always On: Automatically”No setup needed. Every email from Tesoro gets:
- Tracking pixel
- Rewritten URLs
- Unique
track_id
Applies to Gmail, Outlook, and IMAP/SMTP.
Viewing Tracking Data
Section titled “Viewing Tracking Data”On the Email Tab of a Record
Section titled “On the Email Tab of a Record”Per sent email:

- Replied + timestamp of first reply
In the Activities Timeline

Limitations: Not Foolproof Data
Section titled “Limitations: Not Foolproof Data”Opens Missing
Section titled “Opens Missing”- Images blocked: Outlook, Apple Mail, Gmail often do not load images automatically
- Text mode: images are not displayed
- Apple Mail Privacy Protection: loads images via proxy, distorts timing
Opens Counted Incorrectly
Section titled “Opens Counted Incorrectly”- Email scanners: corporate security loads all images automatically
- Preview panes: some clients load content on preview
Clicks Missing
Section titled “Clicks Missing”- URL copied and pasted: no click registered
- Corporate security: rewrites or scans URLs, tracking redirect may fail
AVG/GDPR: Your Responsibility
Section titled “AVG/GDPR: Your Responsibility”Points to consider:
- Transparency: mention in your privacy statement that you use email tracking in business communication
- Legitimate interest: often applies to business follow-up, but assess per situation
- Data storage: tracking timestamps are part of the email record and your general data policy
- Data subject rights: access and deletion upon request, including tracking data
Frequently Asked Questions
Section titled “Frequently Asked Questions”Can I disable tracking per email?
Section titled “Can I disable tracking per email?”No, currently automatically applied to all outgoing emails. No per-email toggle.
Does it work with mass emails?
Section titled “Does it work with mass emails?”Yes, each individual email gets its own unique track_id, tracked separately.
No open, but reply: is that possible?
Section titled “No open, but reply: is that possible?”Yes. Email client did not load images, recipient did not click a link, but replied directly. Pixel not triggered, reply still recorded.
Can the recipient see it?
Section titled “Can the recipient see it?”Pixel is invisible (1×1 + hidden CSS). But technically savvy recipients can see it in the HTML source code. Rewritten URLs are visible on hover.
