&gt; so long as everything we want to &quot;point to&quot; and share has a URL<p>This is something I wish was a standard part of email, actually. There are times when I want to refer to an email thread (say, in a ticket in our issue tracker) and I have to resort to either quoting all the relevant parts verbatim or saying something like &quot;for context, search for the email sent on 2015-11-20 by foo@bar with the subject line &#x27;widget is broken&#x27;&quot;. I&#x27;d love something like `mailref:[identifier]` to be widely understood by browsers and email clients.<p>Mailing lists that are readable on the web partially solve this, but it&#x27;s still not great UX to be sent away from my email client just to read another email.
