How to know if a prospect actually read your sales deck
Last updated · Pitchline
Short answer
You can't tell from an email attachment. To know whether a prospect read your deck, send it as a tracked link instead of a file. Document trackers such as DocSend, Papermark or HubSpot Documents show opens and time per page. A Voice PDF from Pitchline shows the same, and also records the questions the prospect asked while the AI agent presented the deck.
Option 1: Email attachment (no visibility)
A PDF attached to an email tells you nothing. Open tracking might show the email was opened, but Apple Mail Privacy Protection inflates those numbers, so even that signal is unreliable. You won't know whether the attachment was opened at all.
Option 2: Shared cloud file (minimal visibility)
Google Drive and OneDrive can show that a file was viewed, mostly by people signed in to accounts you can see. You won't get time per page, and anonymous views from outside your organisation are often invisible.
Option 3: Document tracking link (good visibility)
Tools like DocSend, Papermark and HubSpot Documents turn a PDF into a link that logs each visit: who opened it, when, how long they spent on each page, and whether it was forwarded. You learn what the prospect looked at. You don't learn what they thought or what confused them.
Option 4: Voice PDF (visibility plus the prospect's questions)
A Voice PDF tracks the same things as a document link and adds an AI voice agent that presents the deck and takes questions. Because the prospect talks to the agent, you also get:
- every question they asked
- their answers to qualifying questions about budget, timeline and current process
- which slides they went back to
- a separate session for each person the deck gets forwarded to
That's the difference between "they spent 1m 42s on pricing" and "they spent 1m 42s on pricing and asked whether annual billing gets a discount."
What to do with the signal
| What you see | What it usually means | Next move |
|---|---|---|
| Opened within an hour, read every slide | High intent | Follow up the same day |
| Opened, dropped off early | Wrong slide order, or the wrong person | Ask who else should see it |
| Long time on pricing, went back to it | A budget question | Address pricing directly in your follow-up |
| Forwarded to several new people | An internal buying process has started | Ask your champion who the new viewers are |
| Not opened after five days | Not a priority right now | One short nudge, then move on |
