The two kinds of template
A template is a fixed shape you refill: what, when, where, reply-by, and the contact route. The frozen version ends in type your answer and send it back; the living version ends in a link. Everything before the link can be identical, which is the point: the template is the message, the page is what the message opens.
The living template trades one small thing, a few extra seconds of setup before the first send, for three large ones. Answers arrive in a list instead of a scroll. Details get edited without a resend. The deadline sits beside the button and reminds people for you.
