Send a Pitch Deck Investors Actually Open

You attach the deck as a PDF and hit send. The investor opens it in a preview pane, scrolls three slides, and closes the tab. You never find out which slide lost them, and the next email you write is a guess.

The fix is not a better deck. It is a different object: a URL that opens in the browser, keeps the slide order you exported, and reports back which pages held attention.

A PDF loses the investor at the preview pane

An attachment is a file, and a file behaves like a file. It lands in Downloads next to a bank statement, it opens in whatever viewer the phone defaults to, and it pinch-zooms badly on the screen where most decks are read first.

• It is frozen at the moment you sent it: You spot the typo on slide four an hour later, send v4, and the partner still has v3 sitting in the thread. Every correction costs another email.
• It sends nothing back: You cannot tell an unopened deck from one that was read twice. The only signal you get is a reply, which is the one thing you are trying to earn.

A link fixes both at once. You edit the project, the URL keeps working, and the viewer counts pages while the investor reads.

A flipbook opens in the browser with nothing to download

You drop the exported PDF into a flipbook project and it is split automatically into pages, one slide per page, in the order you exported them. The cover takes your company name and a brand color. Source pages want to be at least 1200 px wide, otherwise type on a chart slide goes soft when the investor zooms.

The turn is the part a PDF cannot copy. Click the edge of a page and the sheet curls over with real depth and shadow. Arrow keys work, Home and End jump to the first and last slide, and a swipe turns pages on a phone. One caveat worth knowing before you send: if drag to rotate is on, dragging spins the whole book instead of turning a page, so leave the dock arrows visible for anyone who tries to drag.

The dock is also where the download button lives, and you can switch it off if you do not want a PDF of the deck leaving the page. Hotspots go on any page, so the traction slide can carry a link to the data room and the last page can carry your calendar. Sharing settings are per project: set the deck to unlisted and it is link-only, open to anyone with the URL and out of search. The limits are real and worth planning around: free gives you 3 projects and 50 MB, which a scanned deck can blow past, and free projects keep the i3Dify watermark.

Page-level analytics tell you which slide lost them

Views alone are close to useless during a raise. What changes the follow-up is the heatmaps tab, which shows how many times each page was opened and how long it held attention, next to session duration, device breakdown, country and referrer. That is the difference between knowing the deck was opened and knowing it was closed on the market slide.

Be clear about what it does not give you. Views are aggregated per day with no IP address and no visitor profile stored, so analytics measure attention, not identity, and a second session could be the partner or the associate she forwarded it to. Free is a view count with no analytics screen at all. The dashboard starts on Pro, which is 3 dollars a month or 24 dollars a year.

Read the drop-off before you write the follow-up

Wait a day and open the project analytics before you draft anything. A session that ends on page three tells you which claim did not survive contact, and that page is what your reply should answer. A deck that was reopened does not need more explanation, it needs a time. Sessions measured in seconds mean the cover is doing no work, which is a deck problem you can fix in the editor without resending a file.

A deck that opens in the browser is a deck that gets read to the end, and the pages the investor lingered on are the ones you answer in the follow-up.
