I am using Dropbox to share lots of documents with my clients as I meet with them.  It's also a great way to grab their email address. So I have been doing this for about a month now and wanted to circle back with the clients in which I have shared documents. But, I can't find their email addresses on my Dropbox app for iPad. Are they on my mail server or are they on the Dropbox app?
How can I retrieve the e-mails from my shared folders in Dropbox?
