Turn a messy customer email thread into a clear, friendly reply: give ChatGPT the thread and your facts, check every promise, fix the tone, and send it from Gmail.

## Part 1: Copy the thread

### Step 1: Open the thread

Here's the inbox for Cedar Lane Bakery, a small neighborhood shop. Dana's email thread has four messages, a date mix-up, and two unanswered questions.

![Gmail in Stepthrough’s practice copy, step 1 of 20 (Open the thread): the cursor is on “Dana Whitfield”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-01.webp)

**Step 1 of 20.** This is Cedar Lane Bakery's Gmail inbox. Click **Dana Whitfield**'s thread, **Birthday cake order**, to open it.

### Step 2: Expand all messages

Gmail folds up the older messages, so only the newest one is open. You want the whole story, so click Expand all, the double-arrow icon at the top right.

![Gmail in Stepthrough’s practice copy, step 2 of 20 (Expand all messages): the cursor is on “Expand all”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-02.webp)

**Step 2 of 20.** Gmail folds up the older messages in a thread. Click **Expand all**, the double-arrow icon at the top right of the thread.

### Step 3: Copy the thread

Read it through once. There's the wrong pickup day, a flavor change, and a nut allergy question. If there is anything private in there, like a card number, leave it out. Here, just click the messages.

![Gmail in Stepthrough’s practice copy, step 3 of 20 (Copy the thread): the cursor is on “Ctrl+C”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-03.webp)

**Step 3 of 20.** In real Gmail you select the messages, then press **Ctrl+C** (or right-click and choose **Copy**). Here, click the **messages** to copy them.

### Step 4: Switch to ChatGPT

Now switch over to ChatGPT.

![Gmail in Stepthrough’s practice copy, step 4 of 20 (Switch to ChatGPT): the cursor is on “ChatGPT”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-04.webp)

**Step 4 of 20.** Click the **ChatGPT** tab at the top.

## Part 2: Give ChatGPT the context

### Step 5: Click the message box

You're in a fresh chat. You'll give ChatGPT three things in one message: the thread, the facts, and what a good reply looks like.

![ChatGPT in Stepthrough’s practice copy, step 5 of 20 (Click the message box): the cursor is on “message box”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-05.webp)

**Step 5 of 20.** You are in a new chat. Click the **message box**.

### Step 6: Paste the thread

First, the thread. One line tells ChatGPT what it's looking at, then the emails, oldest first.

![ChatGPT in Stepthrough’s practice copy, step 6 of 20 (Paste the thread): the thread is filled in (“Here is an email thread between my bakery and…”).](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-06.webp)

**Step 6 of 20.** Paste in the thread. One line says what this is, then the four emails, oldest first.

```text
Here is an email thread between my bakery and a customer, oldest message first.

Dana Whitfield (Mon, Sep 21): Hi! I'd like to order a 2-tier birthday cake for my husband's 40th. Chocolate, serves about 30. Pickup Saturday Oct 3 in the morning. Thanks, Dana

Jess at Cedar Lane Bakery (Tue, Sep 22): Hi Dana, you're all set: 2-tier chocolate, serves 30, pickup Sunday Oct 4 at 10 a.m. We got your $40 deposit. - Jess

Dana Whitfield (Wed, Sep 23): Actually can we switch to lemon? And the writing should say Happy 40th, Mike! Also my sister-in-law has a nut allergy, is that ok??

Dana Whitfield (9:14 AM): Hello?? I just noticed your email says SUNDAY. The party is SATURDAY. I haven't heard back about the lemon or the allergy question either. I need to know this is handled.
```

### Step 7: Add the facts

Next, the facts. ChatGPT can't know your schedule, your prices, or what your kitchen can promise, so spell them out. Number them, so you can check them later.

![ChatGPT in Stepthrough’s practice copy, step 7 of 20 (Add the facts): the facts is filled in (“Facts (only promise what is here): 1. We can…”).](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-07.webp)

**Step 7 of 20.** Paste in the facts. These are the only things the reply may promise: the new date, the price, the allergy answer and the discount.

```text
Facts (only promise what is here):
1. We can move pickup to Saturday, Oct 3, at 10 a.m.
2. Lemon is fine, same price: $120 total.
3. "Happy 40th, Mike!" on top is fine, no charge.
4. Our lemon recipe has no nuts, but our kitchen also bakes with nuts, so we can't promise any cake is nut-free.
5. The Sunday date was our mistake. The owner approved 10% off the $80 balance, so $72 is due at pickup.
6. Sign it: Jess, Cedar Lane Bakery.
```

### Step 8: Say what a good reply looks like

Last, tell it what a good reply looks like: the tone, the three questions to answer, and a word limit. And one rule that matters most: don't invent details or promise anything that isn't in the facts.

![ChatGPT in Stepthrough’s practice copy, step 8 of 20 (Say what a good reply looks like): the instructions is filled in (“Write my reply to Dana. Tone: warm, friendly…”).](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-08.webp)

**Step 8 of 20.** Paste in the instructions: the tone, the three questions to answer, a word limit, and a rule not to invent anything.

```text
Write my reply to Dana. Tone: warm, friendly and professional, like a small neighborhood bakery. Apologize once for the date mix-up. Answer all three of her questions clearly: the date, the lemon change and the nut allergy. Keep it under 150 words. No subject line, since it's a reply in the same thread. Don't invent details or promise anything that isn't in the facts.
```

## Part 3: Get the first draft

### Step 9: Send it

Thread, facts, and instructions, all in one message.

![ChatGPT in Stepthrough’s practice copy, step 9 of 20 (Send it): the cursor is on “Send”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-09.webp)

**Step 9 of 20.** Thread, facts and instructions are all in. Click the **Send** arrow.

## Part 4: Check every promise

### Step 10: Read the draft, then click the message box

That's a solid first draft. It apologizes once, fixes the date, and answers every question. But read the allergy line: completely nut-free. That isn't in your facts. A draft can sound careful and still promise too much.

![ChatGPT in Stepthrough’s practice copy, step 10 of 20 (Read the draft, then click the message box): the cursor is on “message box”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-10.webp)

**Step 10 of 20.** Read the draft closely. It sounds great, but look at the allergy line. Then click the **message box**.

### Step 11: Ask ChatGPT to check its promises

Ask ChatGPT to check its own work: every promise in the reply, next to the fact that backs it up.

![ChatGPT in Stepthrough’s practice copy, step 11 of 20 (Ask ChatGPT to check its promises): the check is filled in (“Check that reply against my facts. Make a…”).](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-11.webp)

**Step 11 of 20.** Paste in the check to ask for a table of every promise and the fact behind it.

```text
Check that reply against my facts. Make a table of every promise or claim in it and the fact that backs it up. Flag anything the facts don't support.
```

### Step 12: Send the check

![ChatGPT in Stepthrough’s practice copy, step 12 of 20 (Send the check): the cursor is on “Send”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-12.webp)

**Step 12 of 20.** Click the **Send** arrow.

## Part 5: Fix it and warm it up

### Step 13: Read the table, then click the message box

Five of the six claims match a fact. The allergy line doesn't, and ChatGPT even suggests wording your facts support. Still compare the table with your own facts, since you know the business.

![ChatGPT in Stepthrough’s practice copy, step 13 of 20 (Read the table, then click the message box): the cursor is on “message box”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-13.webp)

**Step 13 of 20.** Five of the six claims match a fact. The allergy line does not, and ChatGPT suggests safer wording. Click the **message box**.

### Step 14: Ask for specific changes

Now ask for specific changes, not just make it better. Use the safer allergy line, make it a little warmer and shorter, and keep every other fact exactly the same.

![ChatGPT in Stepthrough’s practice copy, step 14 of 20 (Ask for specific changes): the fix is filled in (“Use that allergy wording. Then make the whole…”).](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-14.webp)

**Step 14 of 20.** Paste in the fix: use the safer allergy wording, make it warmer and under 120 words, and keep every other fact the same.

```text
Use that allergy wording. Then make the whole reply a little warmer and shorter, under 120 words. Keep every other fact exactly the same. Reply with just the email.
```

### Step 15: Send the fix

![ChatGPT in Stepthrough’s practice copy, step 15 of 20 (Send the fix): the cursor is on “Send”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-15.webp)

**Step 15 of 20.** Click the **Send** arrow.

## Part 6: Send it from Gmail

### Step 16: Copy the reply

Read it once more. The date is fixed, the allergy answer is honest, and the discount is right. It sounds like a real person at a neighborhood bakery.

![ChatGPT in Stepthrough’s practice copy, step 16 of 20 (Copy the reply): the cursor is on “Copy”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-16.webp)

**Step 16 of 20.** Read the final reply. Then click the **Copy** button under it.

### Step 17: Go back to Gmail

Back to Gmail.

![ChatGPT in Stepthrough’s practice copy, step 17 of 20 (Go back to Gmail): the cursor is on “Gmail”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-17.webp)

**Step 17 of 20.** Click the **Gmail** tab at the top.

### Step 18: Click Reply

Under Dana's last message, click Reply. Your answer stays in the same thread, which is why you told ChatGPT to skip the subject line.

![Gmail in Stepthrough’s practice copy, step 18 of 20 (Click Reply): the cursor is on “Reply”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-18.webp)

**Step 18 of 20.** Under the last message, click **Reply**.

### Step 19: Paste the reply

![Gmail in Stepthrough’s practice copy, step 19 of 20 (Paste the reply): the reply is filled in (“Hi Dana, I'm so sorry about the mix-up. The…”).](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-19.webp)

**Step 19 of 20.** Paste in the reply to drop in the reply you copied. In real Gmail, press **Ctrl+V**.

```text
Hi Dana,

I'm so sorry about the mix-up. The Sunday date was our mistake, and it's fixed: your cake will be ready for pickup on Saturday, October 3, at 10 a.m.

Lemon is no problem, same price, and we'll write "Happy 40th, Mike!" on top at no charge.

About the allergy: our lemon recipe has no nuts, but our kitchen also bakes with nuts, so we can't guarantee the cake is nut-free. I wanted you to know so your sister-in-law can decide what's right for her.

To make up for the date error, we've taken 10% off your balance. With your $40 deposit, $72 is due at pickup.

Happy birthday to Mike!

Jess
Cedar Lane Bakery
```

### Step 20: Read it, then send

One last read before it goes out. ChatGPT wrote the draft, but you're the one sending it, so check the date, the price, and the allergy answer. Everything's right.

![Gmail in Stepthrough’s practice copy, step 20 of 20 (Read it, then send): the cursor is on “Send”, highlighted.](https://learn.ynteractive.com/content/guide/chatgpt-reply-faster/step-20.webp)

**Step 20 of 20.** Read it one last time: the date, the price and the allergy answer. Then click **Send**.

## Now do it yourself, free

Reading the steps is a start. Doing them is how it sticks. The interactive lesson puts you in a practice copy of ChatGPT: you do every step yourself, it checks your work, and “Do it for me” finishes any step you get stuck on. Nothing touches your real accounts.
