AI checking is not connected yet. You can still rewrite and review your text. Results will appear here when the detector is enabled.
Different detectors can disagree. A human classification here does not guarantee the same result elsewhere.

Same recipient, review status, request, deadline and link. Shorter opening and closing.A useful email tells the recipient what happened, what you need and what comes next. AI-assisted drafts often bury that information inside a formal introduction or a repeated closing. Email mode helps edit the wording while keeping the relationship and the request in view.
Replace ceremonial openings with a direct update when the meaning supports it. Keep the specific action you are asking the recipient to take. A polite request can stay polite without several sentences announcing that you have a request.
Lock recipient names, links, dates and any exact phrase the recipient needs to recognize. Read the complete sentence around each detail: a preserved deadline does not help if responsibility for meeting it changes.
Retain existing greetings and sign-offs. Check whether the draft is offering help, asking for a review or confirming a decision. A scheduled update must not turn into a guaranteed delivery, and a request must not become an approval.
Start with an English draft you have permission to edit. Add a writing sample if you want to match your voice.
Lock numbers, links, quotes, and the phrases you need to keep. Check any suggested names before you rewrite.
