To track if an investor opened your pitch deck, share it as a tracked link using a tool like Prezdo rather than attaching a PDF to an email.
To track if an investor opened your pitch deck, share it as a tracked link using a tool like Prezdo rather than attaching a PDF to an email. You'll see exactly when they opened it, which pages they read, and how long they spent on each slide.
Why email attachments don't work for tracking
When you send a PDF attachment, you lose all visibility. You don't know if it was opened, forwarded, or deleted. The PDF sits in their downloads folder forever.
The better method: gated document links
Instead of attaching your deck, upload it to a document tracking platform and share a link. The link opens a browser-based viewer — the PDF is never downloaded. Every view is logged.
What you can track with Prezdo
- Who opened it: Every viewer's email address (verified via OTP)
- When they opened it: Date and time of each session
- Which pages they read: Page-by-page time tracking
- How long they spent: Per-page and total session time
- If they re-opened it: Every return visit is logged separately
- Real-time notification: Get pinged the moment they open it
How to read the signals
- Re-opens your deck 3× in 2 days → High interest. Follow up immediately.
- Spent 4 minutes on the pricing/market size slide → They like the business. Come prepared to defend your numbers.
- Read the team page and nothing else → They're vetting the people, not the product yet.
- Opened for 8 seconds and closed → Didn't connect. Reconsider your cover slide or subject line.
Step-by-step: set up tracking in 5 minutes
- Go to prezdo.com and create a free account
- Upload your pitch deck PDF
- Set access to "Any email + OTP" (investors verify their email to enter)
- Copy your link: ir1.prezdo.com/seed-deck
- Share this link instead of the PDF in your outreach email
- Open your Prezdo dashboard to see viewer activity in real time
What not to do
Don't use DocSend's tracking if you're on their free or basic plan — the analytics are stripped out. Don't use Google Drive — it logs "someone viewed" but not page-by-page detail. Don't use email tracking pixels — investors know to block them.
