PDFTrackr
Every proposal, deck or report you send can win or lose a deal, and PDFTrackr tells you how it landed. Share it as a secure tracked link and see who opened it, which pages they read and where they stopped, with bots and email scanners filtered out so the numbers are real.
The part worth paying for is Signals: who came back, who is genuinely engaged and who is worth a call now, plus a per-recipient verdict on whether a prospect read it and an alert the moment they open it or return.
You also decide who can open a document at all: allow lists, block lists and a six-digit email verification code, alongside password, expiry, download control and watermarking.
Free is complete: 500MB, full page-by-page analytics, 12-month history, virus scanning, no card. Pro ($9/month or $84/year) adds Signals, alerts, verdicts, CSV export, bulk links, folders and versioning, and every new account runs on Pro free for 14 days.
