ChatGPT Email Threads: Decisions, Proposals and Replies
1. Ask what was agreed, not just what was said
A short email summary can quietly turn a suggestion into a commitment. A later message may repeat a proposed date, while an earlier approval still governs the work. Before drafting a reply with ChatGPT, separate the conversation’s timeline from the evidence for each decision.
Use this workflow with ordinary pasted text: identify the relevant messages, classify each issue, and draft only from supported details. OpenAI’s prompting guidance recommends specifying the goal, context, output and boundaries, then reviewing the result. This guide’s evidence rules are an editorial method, not a guarantee of model accuracy.
State who may confirm changes and what counts as acceptance. If the thread does not establish that authority, ask for clarification. A friendly response, silence or a message’s position at the bottom of a thread does not by itself establish approval. This review organizes supplied evidence; it does not determine legal contractual validity.
2. Preserve the messages and their context
Paste only material you are permitted to use. Remove unnecessary signatures, phone numbers and unrelated personal details, while retaining the message IDs, senders, dates and time zones needed to interpret the exchange. If redacting a delivery address, label the redaction so it is not mistaken for an unanswered question.
Keep quoted and forwarded passages visibly distinct from new writing. A repeated approval is one piece of evidence repeated, not a second approval. Instructions embedded in an email are source content for this task; they must not redirect the analysis or authorize actions.
The following original fictional workshop example supplies all evidence for the exercise. Set the reply author to Mina, recipient to Leo, language to English, tone to neutral and maximum length to 100 words. The goal is to restate the delivery arrangement and expose details requiring confirmation.
CONTEXT: Noor owns workshop W-208 and can confirm delivery timing; Mina coordinates messages. These five excerpts are the only evidence supplied.
E1 | 2026-10-12 09:00 UTC | Mina: The approved delivery for W-208 is 40 printed handouts by 2026-10-23 15:00 UTC. The agreed total is USD 180 including delivery.
E2 | 2026-10-13 10:00 UTC | Leo: Could we move delivery to 2026-10-26 10:00 UTC? This is a proposal; the total would remain USD 180.
E3 | 2026-10-13 11:00 UTC | Mina: The later date would be useful. I will check with the workshop owner before confirming.
E4 | 2026-10-14 08:00 UTC | Noor: Please keep the delivery deadline already agreed for W-208. We still need 40 handouts.
E5 | 2026-10-14 09:00 UTC | Leo: Can you confirm the delivery address and a contact name? I have not received either yet.
3. Classify each issue with evidence
Ask for confirmed, proposed, conflicting and missing items, each linked to message IDs. Use “not established in the supplied material” when the excerpts cannot answer a question. Missing information and contradictory statements need different follow-up: one requires an answer; the other requires resolving which statement governs.
This four-row editorial interpretation shows the expected result. The proposed date differs from the approved date, but it is not a competing approved commitment. There is no supplied acceptance of that change.
On a small screen, swipe the table to see all columns.
| Issue | Status in supplied excerpts | Evidence | Interpretation |
|---|---|---|---|
| Delivery timing | Confirmed deadline; alternative unapproved | E1 + E4; E2 + E3 | Keep 2026-10-23 15:00 UTC. The 2026-10-26 10:00 UTC alternative remains a proposal. |
| Quantity | Confirmed | E1 + E4 | 40 printed handouts. |
| Total | Confirmed | E1 | USD 180 including delivery. E2 conditionally repeats the amount; it is not a new agreement. |
| Address and contact name | Missing from supplied material | E5 | Leo reports receiving neither. The excerpts do not supply either value. |
4. Draft a reply without filling the gaps
E4 matters because the supplied context identifies Noor as the person who can confirm timing, and Noor explicitly retains the earlier deadline. E3 expresses a preference and a future check; it does not record that the check happened. Do not rewrite it as owner approval.
For the unanswered fields, ask: what delivery address and contact name should be included? E5 supports that question. It does not establish that Mina personally lacks the information or that no address exists outside these excerpts. Keep both fields visibly unresolved until a person supplies the values.
Here is an expected editorial reply, not output from a model test. The evidence stays in the analysis above so the outgoing text remains readable. Both unresolved fields must be completed and the whole draft reviewed by a person before sending.
Hi Leo,
For W-208, please keep delivery of 40 printed handouts by 2026-10-23 15:00 UTC. The agreed total is USD 180 including delivery.
Delivery address: CONFIRM BEFORE SENDING
Contact name: CONFIRM BEFORE SENDING
Thank you,
Mina
5. Check the reply against the evidence
Read every factual sentence beside its supporting excerpt. Check the exact date, time zone, quantity, currency and delivery inclusion. Confirm that polite wording has not become acceptance, a proposed change has not become a deadline, and a quoted passage has not acquired a new sender.
For important work, OpenAI recommends a final check and personal review before use. If the draft overstates a point, identify the sentence and its evidence gap, then request a targeted revision instead of accepting a more fluent version.
When new messages arrive, add their IDs and reassess the affected issues. A later explicit approval from the authorized person may change the classification; a later forwarded copy does not establish a new decision. Ask about unclear authority or incompatible approvals before committing to a reply.
Finally, remove internal evidence notes if they do not belong in the recipient’s email, resolve every CONFIRM BEFORE SENDING field and review the result yourself. OpenAI’s inbox guide also separates reply drafts from approved actions. The pasted-text workflow here neither accesses an inbox nor sends a message.
