Track If Someone Opened Your Email Attachment: The Method That Works
You can't track email attachments. Once you attach a PDF, deck, or document to an email in Gmail or Outlook and hit send, it's gone. You don't know if they opened it, read it, or deleted it.
But share a tracked link instead of attaching a file, and you see who opens it, which pages they read, how long they spend on each, and whether they share it with someone else.
Why email attachment tracking doesn't work natively
Email attachments are copies. The moment you attach a file, the recipient gets their own copy stored on their device. There's no connection back to you. No server to log a view. No way to know what happened.
Read receipts don't help either. Gmail personal accounts don't support them, and most recipients decline them. Pixel tracking only tells you the email was opened, not whether the attachment was read. Read the full explanation

How tracked links work
Instead of attaching a file, upload it to HummingDeck and share a tracked link. The recipient clicks the link and views the document in their browser. Every interaction is recorded.
Personal links
Create a link for a specific person or company. You see their name, engagement, and whether they forwarded it. Each recipient gets their own link.
Lead Magnet links
Share your document publicly and collect emails. Anyone who wants to view it enters their email first.

Upload your file
Drag and drop any PDF, PPTX, DOCX, or HTML file. Or use the Google Slides/Docs add-on to publish directly from the editor.
Get a tracked link
One unique link per recipient. Share it via email, LinkedIn, Slack, or anywhere you'd normally attach a file.
See what happens
Who opened it. Which pages they read. How long per page. Whether they forwarded it. When they came back. All in real time.
Works with every email client
Gmail, Outlook, Apple Mail, or any other email client. You're not replacing your email setup. You're replacing the attachment with a link.
The recipient doesn't need to install anything. They click the link and view the document in their browser.
Who uses this
