How to see if someone opened your PDF
You cannot see whether someone opened a PDF attachment. You can see it when you send the PDF as a tracked link. Here is how each method works and what it proves.
The short answer
An email attachment cannot tell you if it was opened. Once the PDF is on the reader's device, it opens in their own app and sends nothing back to you.
To know, send the PDF as a link instead. The link opens the file in a web viewer, which records who opened it, when, and how long they spent on each page.
Why read receipts do not answer it
A read receipt, where your email app offers one, reports that the email was opened. It is sent only when the reader agrees. It says nothing about the attachment.
Email tracking pixels have the same limit. They load an image in the email, not in the PDF. Some mail apps block images or load them on their own, so the signal can be wrong.
Methods that work, and what each proves
- A tracked link with an email door. It shows which email address opened the PDF, and the time on each page.
- A tracked link with an email code. It proves the reader controls that inbox, not only that they typed it.
- A Google Drive link shared with specific people. Its Activity dashboard shows viewers for work or school accounts and signed-in viewers, without time per page.
- Asking. A short note that asks whether the PDF came through still works.

What the report shows
- Each reader by email, with the time of the first open.
- How many times they came back.
- Active reading time, which leaves out idle time.
- Time on each page, and how far they got.
- A replay of each visit.
Be open about it
Tell readers the link is tracked. One line in your email is enough, and it keeps their trust.
