I get a lot of emails (from various companies) that have "action required" and no action required at all. Usually "you've logged in from a new device, you don't need to do anything unless you've been hacked."
I get your point, and that's true. IMHO, I rather have some "action required" mails that won't need action than a single without the prefix that will require action.
AWS at least prefixes mails with "[ACTION REQUIRED]" if there _might_ be some action on your side required.
And by coubting the mails that are coming in today with "important information", I can fully understand if you'll miss one.
