Yeah… I don't really see much of a problem as proposed by Bob. Any
verification emails for any purpose should always be related to an
action the user did very recently. I.e. they visited a site or used an
application, whatever the route and method but they should already /be
expecting an email verification/.

Any verification should certainly be worded better, yes :).
