To get detailed statistics about how your recipient interacted with your PDF documents, we need to convert it into trackable links. And when you send documents with Docsify it opens as web-page with their own URL. So branding gives you an opportunity to customize that URL. Standard (by default) - "present.docsify.net/.." Brand - "yourcompanyname.docsify.net/..." Corporate - "yourcompanyname.com/..." https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/GLQDKLa8wd/resources/sBb10cwhGC/1.png (1 (121696809199).png) Brand and Corporate URL settings are available for PRO plan only.
