Here is how to use ChatGPT for emails: tell it who the email is to, what you want to happen, and the tone, then paste in any email you are replying to and ask for a short draft. Read it, fix names, dates and prices, and send it yourself. It writes the first draft. You stay in charge of what goes out.
That works on the free plan with plain copy and paste. If you connect Gmail or Outlook, ChatGPT can also search your inbox and, on paid plans, send a draft for you after you approve it. Below are the steps, prompts written for the emails a small business actually sends, and the places it goes wrong.
Step 1: Give it the context it cannot guess
A vague prompt gets a vague, wordy email. ChatGPT does not know your business, your customer, or what happened last week, so tell it. Four things cover most emails:
- Who it is to: a new customer, a regular, a supplier, a landlord.
- What you want: book the job, get paid, say no, calm someone down.
- The facts: dates, prices, what was agreed. Only the ones you have checked.
- The tone and length: for example, “friendly, plain, under 120 words, no exclamation marks.”
To stop repeating this, put your basics in ChatGPT’s Personalization settings or in a saved note you paste in: your business name, what you do, your sign-off, and words you never use. A two-chair salon might write: “I run a small hair salon. Write like a friendly owner, short sentences, sign off as Maria.”
Step 2: Draft a new email
Start with the job, then the facts, then the limits. This prompt pattern works for almost anything:
Write an email to [who] about [what]. I want them to [action]. Facts: [list]. Tone: friendly and direct. Under [number] words. Give me two subject line options.
Ask for two or three versions if the first one does not sound like you. Then tell it what to change (“shorter”, “less formal”, “drop the second paragraph”) instead of starting over.
Step 3: Reply to an email you received
This is where ChatGPT saves the most time. Paste the customer’s email, then say in one line what your answer is. It handles the wording.
Here is an email from a customer: [paste]. Write a polite reply that says [your answer in one sentence]. Answer every question they asked. Match their tone. Under 100 words.
Not sure how an email comes across? Ask first: “Does this customer sound upset, and what are they really asking for?” Then write the reply.
Step 4: Rewrite and edit your own drafts
You do not have to let ChatGPT write from scratch. Write your own rough version, then paste it in with one instruction:
- “Make this shorter and clearer. Keep every fact.”
- “Make this sound calm, not annoyed.”
- “Fix the grammar only. Do not change the wording.”
- “Turn these notes into a tidy email: [notes].”
The “keep every fact” line matters. Without it, ChatGPT sometimes drops a detail or softens a deadline.
How to use ChatGPT for emails you send every week
Swap the brackets for your details. Each one is a starting point, not a script.
Following up on a quote
Write a short, no-pressure follow-up to [name] about the quote I sent [days] ago for [job]. Offer to answer questions or adjust the scope. Under 80 words.
Chasing a late payment
Write a polite but firm reminder that invoice [number] for [amount] was due on [date]. Include how to pay: [payment link or method]. No guilt, no threats. Under 90 words.
Answering a complaint
A customer wrote this: [paste]. Write a reply that thanks them, says sorry for [the specific problem], and offers [your fix]. Do not admit to anything beyond that. Under 120 words.
For anything that could turn into a dispute, have your attorney look at the reply before it goes out.
Rescheduling or cancelling
Write a short email telling [name] I need to move their [appointment] on [date]. Offer these times: [times]. Apologize once. Under 70 words.
Saying no to a job
Write a friendly email turning down [request] because [reason]. If it fits, suggest [alternative or referral]. Under 80 words.
Summarizing a long email thread
Summarize this thread in five bullet points: what was agreed, what is still open, and what I need to do next. [paste]
Using ChatGPT with Gmail and Outlook
You have two options: copy and paste, or connect your inbox. Copy and paste works on any plan with any email account. Connecting lets ChatGPT read and search your mail without you pasting anything.
To connect, open ChatGPT’s Settings, select Plugins, pick Gmail or Outlook Email, and sign in to the account you want it to use. OpenAI says which apps you see depends on your plan, region and workspace, and that ChatGPT may ask for your approval before it reads something or takes an action. Gmail first came to Pro and Plus users in August 2025.
Once connected, you can ask things like “Find the last email from [supplier] about the delivery date” or “Draft a reply to the newest email from [customer].” According to OpenAI’s June 2026 release notes, ChatGPT can then draft and send that email from the chat after you choose to send it. Sending is on the web, for Plus, Pro, Business and Enterprise plans. Not sure a paid plan is worth it for this? See is ChatGPT Plus worth it for small business.
Outlook users with shared mailboxes, such as an office inbox, can also ask ChatGPT to read from and send plain-text email on behalf of that mailbox, per OpenAI, as long as their Microsoft permissions allow it.
On privacy, OpenAI says it does not train its general models on data pulled directly from connected Google apps. That changes if you paste the content into a chat yourself, it shows up in ChatGPT’s reply, or you submit the chat as feedback. You can disconnect Gmail at any time in settings.
What not to paste into ChatGPT
Every email you paste in becomes part of a conversation. On Free, Plus and Pro, OpenAI says data sharing for model training is on by default. You can turn off Improve the model for everyone under Settings, Data controls, and new chats will not be used for training. OpenAI says Business and Enterprise workspace content is not used for training by default.
Even with that off, keep these out of the chat:
- Card numbers, bank details, passwords and login codes.
- Social Security numbers or other ID numbers.
- Health details about clients, if your business handles them. Talk to your compliance advisor before using any AI tool with that information.
- Anything a customer told you in confidence that the reply does not need.
A first name and the question they asked are usually all ChatGPT needs to write a good reply.
Limits: what ChatGPT will not do for your inbox
- It does not know your facts. If you do not give it a price, date or policy, it may make one up. Check every number before sending.
- It can sound like a robot. Long greetings, “I hope this email finds you well”, too many adjectives. Ask for shorter and plainer, or cut it yourself.
- It is not your email marketing tool. ChatGPT can write a newsletter or promo email, but it does not manage your list, unsubscribes or send schedules. For that, see our guide to AI email marketing tools.
- Promo emails have legal rules. The FTC says the CAN-SPAM Act covers every commercial email, not just bulk mail. Each one needs an honest subject line, your physical postal address and a clear way to opt out. ChatGPT will not add those unless you ask, so check them yourself, and ask your attorney if you are unsure.
- Skip letting it send on its own. Even with Gmail connected, read every draft before you approve it. One wrong name or price costs more than the time you saved.
