What is the difference between ARC Watermarking and ARC Delivery?

Two ways to get review copies out:

• ARC Watermarker (free to preview, unlock to remove the preview overlay): stamps a personalized copy per reviewer and gives you a ZIP plus the traceability manifest. You send the files however you like (email, BookFunnel, etc.). Everything happens in your browser — nothing uploads.
• ARC Delivery (a paid add-on service): we email each reviewer their personalized copy with a unique, tracked download link, so you can see who's actually downloaded. Replies go straight to you, and copies are stored only until the links expire (30 days), then deleted.

Use the Watermarker if you want to handle sending yourself; use Delivery if you'd rather we mail the copies and track them. Delivery is a separate service and isn't part of the Complete Book — making the copies is included, us mailing them is not.
