I just did some further testing. Subject line URLs work fine in standalone iOS Mail.app and macOS Mail.app, but do not work in the browser-based mail for iCloud using either Safari or FireFox on macOS. :-)
So much for consistency! As I said: I used to use this capability with Mail.app on macOS at work. Most of the time, however, if I send URL-only to someone now, it's as a txt not an email; it's actually a bit awkward to do it with Mail compared to txt… The macOS and iOS Message apps process the link, extract an image or preview on both the sender's and recipient's txt stream, and add a click-/tap-able region to jump to the web page if desired. Whether this meets with some set of RFC codes or not I haven't the foggiest, nor am I interested to find out. If I had to copy and paste the URL from the subject to a browser to get to the link, well, that's clumsy but I suspect the world wouldn't end… :-) G — "Simplify, simplify, simplify.” ~ Henry David Thoreau "One 'simplify' would have sufficed." ~ Ralph Waldo Emerson > On Jun 30, 2018, at 5:17 AM, Jan van Wijk <pen...@dfsee.com> wrote: > > On Fri, 29 Jun 2018 14:15:14 -0700 Godfrey DiGiorgi wrote: >> >> It's a short cut, Ann rather than writing a note that requires a text >> body, you just send the link as the subject line.
