Why an email landed in the wrong category
Your secretary sorts by reading content, so an unusual email can land in the wrong place. To fix it, change the item's category yourself or ask your secretary in chat to recategorize it, and it learns from the correction. There's no reprocess button, but you can undo its recent actions, and nothing is ever lost.
Why it happens
Your secretary sorts mail by reading what's actually in it, not just who sent it or what folder it came from. That's what lets it tell a real task from a newsletter. Most of the time it gets the call right, but an unusual email, a marketing message dressed up as a personal note, a receipt that reads like a request, can land somewhere you didn't expect.
When that happens, nothing is lost. The email is still there and still searchable. It's just filed under a type or category you wouldn't have picked, and that's easy to correct.
Fix it yourself
Open the item and change its category or type to the one you want. This works for FYIs, Highlights, and the things your secretary pulled out as Action Items. There's no one-click reprocess for an email. You correct the item directly, which is faster and gives you the result you want straight away.
Your secretary remembers these corrections. Move a sender or a kind of message a couple of times and it starts placing similar mail the way you prefer.
Ask your secretary, or undo
You can also just tell your secretary in chat. Something like "move this to Newsletter" or "this isn't a task" works, and it handles the change for you. The same chat is where it picks up your preferences over time.
Changed your mind, or the secretary moved something you didn't want moved? You can undo its recent actions and put things back. For more on chatting with your secretary, see Chat with your AI secretary.
