How to change the header of the message?

Added by Vladislav Guziev 5 months ago

I've been doing redmine not long ago, I set up a notification for this article https://www.redmine.org/projects/redmine/wiki/RedmineReminderEmails , everything worked. How can I change the header of the post? Can someone tell me where to find it? Or does it generate itself and there is no way to change it?

I am attaching a screenshot sorry for the russian text.
