Actually it seems that I can send from any page, but not every time. I originally tested by filling in the contact form on each page one by one in one sitting. I think I got the first two or three. The next time I did it, I sent from the ones that didn’t work last time. I got the first two. Why? Obviously a real user wouldn’t be filling in the contact form on every page, so if I get at least one from each attempt at contact that should be ok.
