Understand email-open tracking limitations
Avoid treating a tracking-pixel request as conclusive proof that the intended recipient read the correspondence. The guide then takes you through the correct route, the checks to complete before making changes, the workflow in order, and the evidence to review afterwards.
Where to goLetter Manager read-receipt evidence review
Before you start
- Use an authorised account and confirm the customer, external recipient, template, letter or configuration is the intended one.
- Follow the exact route shown above and verify the stored record, generated file and delivery evidence instead of relying on an alert alone.
What you’ll accomplish
Avoid treating a tracking-pixel request as conclusive proof that the intended recipient read the correspondence. These instructions follow the inspected module’s live hook, route, controller, model, installer, PDF helper and view flow.
Follow these steps
- Verify the email was sent to the intended address.
- Check open count, time, IP source, user agent and proxy note together.
- Consider remote-image blocking, prefetching, privacy proxies and security scanners.
- Use stronger acknowledgement or e-signature evidence when legally required.

Module version1.0.0
Exact routeLetter Manager read-receipt evidence review
EvidenceVerify the history row, PDF, email metadata, open evidence, signature, public page, client view or postal fields produced by this flow.
Rules the system enforces
- A recipient can read an email without loading images.
- A proxy or scanner can load the pixel without a human reading it.
- The module does not establish unique-reader identity from the open event.
How to confirm it worked
- The requested letter, template, setting, file or tracking detail is created or updated through the supported route.
- The history row, generated PDF, email/send metadata, public verification, signature evidence, client view or postal display agrees with the action.
- Any warning, missing file or failed send is investigated rather than bypassed.
Security, privacy and operational checks
- Apply least privilege and verify recipient identity before sending or exposing public links.
- Protect PDFs, enclosures, signatures, verification URLs, email-open metadata, IP addresses and customer data under organisational policy.
- Test configuration and deployment changes with controlled records before production-wide use.
- Interpret email opens and e-signatures according to their documented technical limitations.
Important code-backed limitationRead-receipt evidence is indicative, not definitive proof of human receipt or comprehension.
