Before sending an AI-drafted email, check that it serves your real purpose, verify its factual and personal claims against reliable sources, review its clarity and tone, and inspect the recipients, links, attachments, and commitments. A polished draft is not proof that its contents are true or that you meant to say them.

1. Check that the email says what you intend

Before editing individual sentences, state the email’s purpose in your own words: what should the recipient understand or do? Then compare each paragraph with that goal. Remove background the draft invented, details that do not help, and requests or positions you did not intend to express.

This first check catches a problem that grammar and spell-checking cannot: an email can be fluent and still misrepresent your intent.

2. Verify every factual claim

Check names, titles, dates, numbers, quoted wording, links, and references to policies or laws against the relevant source material. For example, confirm a meeting date in the calendar, a figure in the original report, and a quotation in the document it is attributed to. If you cannot establish a claim, remove it or qualify it rather than presenting it as fact.

The UK Information Commissioner’s Office (ICO), writing in the specific context of Freedom of Information requests, advises: “Please review the text of your request carefully and don’t assume AI is right.” The same practical caution applies when checking an AI-drafted email: fluent phrasing is not evidence. Read the ICO’s FOI and AI guidance.

3. Treat claims about people with extra care

Check that statements about a person are supported by reliable, current information and are appropriate to include. Be especially cautious with claims about someone’s intentions, performance, circumstances, or likely behavior: a model’s inference or prediction is not a verified fact. If you cannot substantiate a personal claim, do not send it as though it were established.

The ICO’s guidance on AI and data protection says that records should make clear when personal data represents a statistically informed guess. This is UK data-protection guidance, and its legal application depends on the situation; it is not a substitute for advice about a particular case. The ICO page retrieved on 7 October 2026 notes that the guidance may be under review. See the ICO’s guidance on accuracy and statistical accuracy.

4. Check clarity, tone, and the next step

Read the message from the recipient’s point of view. Is the main point easy to understand? Is the requested action, owner, or deadline clear, if one is needed? Cut unnecessary wording and revise sentences that sound abrupt, overconfident, or insensitive for the relationship and situation.

The ICO’s human-review guidance says, “AI-generated content can sometimes sound abrupt, or otherwise inappropriate.Please check the tone before sending.” That guidance is under review and comes from a UK data-protection context, but the practical reminder is useful: check the tone of the actual message, not just whether it is grammatically correct. Read the ICO’s human-review guidance.

5. Remove unapproved commitments and disclosures

Look for promises, admissions, deadlines, decisions, or instructions the draft may have added or strengthened. Keep only those you are authorized and willing to make. Also check whether confidential or personal information is necessary and intended for every person who will receive the message.

6. Check the sending fields and exact final message

  1. Review recipients: Confirm the addresses in To, Cc, and Bcc, especially when names are similar or the message contains sensitive information.
  2. Inspect attachments: Open each attached file and verify that it is the intended version and contains nothing you do not mean to share.
  3. Test important links: Open them to confirm they work and lead to the intended destination.
  4. Read the final message: Review the exact version in the compose window after all edits, then send only if it still reflects your purpose and approved facts.

These are practical pre-send safeguards, not a verbatim checklist from the ICO. Its FOI guidance recommends careful review, and its human-review material emphasizes human oversight; the recipient and attachment checks are sensible extensions of that final review.

Can AI provenance signals or detectors verify an email?

No. They may offer limited clues about origin, but they do not establish that an email is true, appropriate, or written by a particular person. Use source records to verify claims and your own judgment to assess intent, clarity, and tone.

Provenance signals show limited information about origin

OpenAI says provenance signals can provide information about origin, but do not guarantee accuracy, lack of editing, legal ownership, or correct context. A missing signal also does not prove that OpenAI did not generate the content: signals may be unavailable, unsupported, stripped, or degraded. Read OpenAI’s explanation of provenance signals.

ChatGPT cannot reliably determine authorship

OpenAI says ChatGPT does not have reliable knowledge of whether it wrote a passage or whether another passage was AI-generated, and may make up an answer. Asking it to identify the author is therefore not a dependable way to verify an email’s origin. See OpenAI’s guidance on asking ChatGPT whether it wrote something.

Detector accuracy claims need context

In a March 2025 announcement about its action against Workado, the U.S. Federal Trade Commission (FTC) said independent testing found the company’s detector was 53% accurate on general-purpose content, while Workado had advertised 98% accuracy. That figure describes one detector in the test context reported by the FTC; it is not an accuracy rate for AI writing tools or a way to predict whether a particular email is correct. The FTC announcement described a proposed order, and this article does not establish the matter’s later procedural status. Read the FTC’s announcement.
