When Gmail opens a message containing a bare email address that does not have mailto: link, it "helpfully" turns it into a mailto: link, there is unwanted change of the text styling too.
Is there a web standards tag that authors (such as email newsletter operators) can use to suppress linkification? On Googling, I see some mention of this idea, <nolink></nolink>
and <span class="nolink"></span>
. But I could not find any authoritative page saying that this is what I should use.
