The emails nobody owns

Booking confirmations and order emails are the most-opened messages a brand sends, and usually the least looked after.

Ask a marketing team who owns the booking confirmation, the password reset and the order dispatch email. The answer is usually a pause, then a name of someone who left.

Transactional emails are built once, often by a developer during a platform migration, and then left alone because they work. They send automatically, nobody schedules them, and nobody reviews them in the weekly campaign meeting. Years later they are running on a template that predates the current brand.

Why they matter more than campaigns

A campaign is opened by a fraction of the list. A booking confirmation is opened by almost every guest, often several times: once on arrival, again when they need the reference, again the night before. It is read at the moment of highest intent and highest anxiety.

It is also the email most likely to be read on a phone, in dark mode, in a hurry. If the reference number is buried, the address is an image or the button collapses in Outlook, the guest notices.

What usually goes wrong

  • The design predates the last rebrand: old logo, old colours, a footer with a dead social network.
  • Each property or market has drifted into its own version.
  • Key information is set as an image, so it vanishes when images are blocked.
  • Nobody has tested it in dark mode, where dark logos on transparent backgrounds disappear.
  • Agency-built and platform-built templates sit side by side with different structures.

Where to start

Make a list of every automated email you send and who owns each one. Then put the three most-opened ones through a rendering test in Outlook, Gmail on a phone and Apple Mail in dark mode. That is usually enough to make the case for treating them as a journey, built from the same components as everything else.
