Document trackers, like DocSend and Papermark
Best for sharing a finished document as a controlled, trackable link
You already have the PDF or the deck. These tools give it a link, access controls and analytics; Papermark is open source and extends into data rooms for due diligence.
Where Salesclick differs: Salesclick is not a wrapper for your document. It builds a personal page per prospect instead, so pick it when you would rather stop sending documents than track them.
