I am using their mobile website (from my Android browser). I found the email link when viewing on a computer (haven`t checked the mobile registry since locating it).The email option is right in the gift registry box. Just start at the top of the box and work your way down, it`s fairly close to the top. Are you using the app or the regular site?
Were you referring to the mobile site when you said their app? Or do they have an app for their site as well (haven`t searched the app store)?
When I looked at the URL link I shortened (where it took me) and the email link, I didn`t notice anything different, so I`m guessing that both would behave the same for whoever was using it or buying a product from your registry...
