There is a thread in the Andriod 10 forum in the OS section "Persistent toast messages." I think this is a "thing" and you may encounter it beyond the email notifications.
That MIGHT be there for you to quickly undelete. What email app are you using? For gmail, when you delete (on my phone) it shows at the bottom as a strip, with an undo command. Yours might be similar but just looks different because you are a different phone with a different ROM. Next time you delete, try tapping the notice and see if you get an option to delete.
