I can only see and set the preheader in the Email Builder under Marketing.
But I use the emails in Automations, where I can neither see nor change the preheaders.
Since I test different emails against each other (for the open / click / unsubscribe rate) and I can see the statistics in the automation, the following is urgently needed:
  1. in the automation when clicking on the email template the possibility to set the preheader there as well.
  2. the possibility to set an alternative preheader in the automation (just like the subject line).
  3. the display of the preheader and subject of the template next to the thumbnail
