Somewhere in your sent folder is a file called Homepage_V4_FINAL_v2.pdf. It took twenty minutes to export and assemble. The feedback it earned? An email that says "looks good, but can the logo be bigger?" — referring, you'd later learn, to V3.
Static Files Create Static Feedback
A PDF strips away everything that makes design reviewable: the interactions, the context, the ability to point at a specific element and say "this one." So clients respond in the only channel left — prose. And prose feedback is where ambiguity breeds.
The Interactive Review Loop
Modern teams share a live link instead: the client sees the current version (always the current version), annotates directly on the design, and answers structured questions instead of drafting an essay. No version confusion, no attachment limits, no "did you see my email?"
The deck isn't coming back. The teams that retire it first get their evenings back first.
