I indeed did not mask en am saying that emails to clients result in the template variable being displayed in the email and not translated to a link, just as you say.This is what it says at the bottom (it's a translation) from "New Activity Notice"": U krijgt deze email omdat u samenwerkt in ticket #%{ticket.number}.Antwoord op deze email om verder te participeren of klik hier voor een compleet overzicht van de berichten in het ticket. It's the same as in the default English template which says this:You're getting this email because you are a collaborator
on ticket #%{ticket.number}. To participate, simply reply to this email
or click here for a complete archive of the ticket thread.
