   Cold-email landing pages

   Different job from the main site. Someone clicked a link in an email, on a
   phone, probably on cellular, and will leave in about eight seconds if the
   page has not told them what this is. So: one column, one CTA, no nav, and
   the form on the page instead of behind a modal.
