PDFTrackr's answer
Sales and business-development teams, consultants, agencies, and founders raising on a pitch deck. Anyone who sends proposals, decks, and reports and needs to know who actually read them and when to follow up.

It separates readers from automated opens. Email security scanners, link previews and crawlers are taken out of the view counts, and the dashboard shows how many were excluded. Pro groups visits under each reader's email and tells you when someone comes back, so you know who to follow up with.
