Yes, AI can send emails for you, but start with drafts. Let the agent write replies that a person reviews and sends. Before it sends anything on its own, set up a separate sending address and the narrowest permission. Write a short list of the email types it may send, and test it on last month’s emails.
This guide is for operations, sales, support and marketing leads, and for the IT person who approves new tools. If your first need is sorting and drafting replies, start with our guide to triaging a shared inbox with AI. This post is about the step after that, giving an agent permission to send.
Can AI send emails for you?
Yes. An AI agent can send email once it is connected to a mailbox with permission to send. What matters is which emails it sends and who checks them first.
There are two modes. In draft mode, the agent writes a reply and leaves it for a person to read and send. In send mode, the agent sends without waiting. Run draft mode first and move a single email type to send mode only after it has been tested.
Permission to read email and permission to send it are separate. Google lists a send-only scope in its Gmail API scopes, as of October 2026. It describes the scope as “Send email on your behalf”. It also lists a restricted scope that can “Read, compose, send, and permanently delete all your email from Gmail”. Google tells app developers that “generally, you should choose the most narrowly focused scope possible”. The wider the permission, the more a mistake can reach.
What can go wrong when an agent sends email?
One named risk is an agent that can do more than its job needs. The OWASP GenAI Security Project calls this Excessive Agency. It says the root cause is typically one or more of “excessive functionality; excessive permissions; excessive autonomy”.
For email, that could be an agent that can delete messages when it only needed to send one. It could also be an agent that sends without anyone checking.
Ordinary mistakes count too. An agent can address the wrong person, quote an old price, or promise a delivery date nobody agreed to. A sent email cannot be recalled in the way a draft can be deleted.
Inbound email adds a further risk. A message from outside your business can contain text written to steer the agent. OWASP says indirect prompt injections “occur when an LLM accepts input from external sources, such as websites or files”. Its Excessive Agency page gives an email example. The app only needed to read mail but could also send. A crafted incoming email then tricks the model into forwarding sensitive information to the attacker. Keep the agent’s ability to act narrow, so a hostile message can do less.
OWASP advises builders of these tools to use human-in-the-loop control “to require a human to approve high-impact actions before they are taken”. As a buyer, you can build that approval into your own process.
Which emails should an agent send on its own?
Only the routine ones that you have tested, and only after a period in draft mode. Anything that commits the business to money, prices, delivery dates or legal terms stays with a person. Confirming a time already booked in the calendar is the exception.
This table is our own suggested starting point, not a rule from any regulator.
| Email type | Example | Start with | Why |
|---|---|---|---|
| Acknowledgement of a new enquiry | “We have your enquiry and will reply soon.” | Send automatically after testing | Low risk, and the wording barely changes |
| Meeting confirmation or reminder | Confirming a booked time | Send automatically after testing | The details come from a calendar entry |
| Reply using an approved FAQ answer | Opening hours, how to reset a password | Draft for approval first | The answer is fixed, but the match to the question can be wrong |
| Quote, price or deadline | A price for a custom job | A person approves every one | It commits the business |
| Complaint, refund, legal or bank details | A refund decision | No, a person writes it | The cost of an error is high |
| Marketing email | Any campaign | No, until consent, sender details and unsubscribe are checked | Consent, sender identification and unsubscribe rules apply, as covered below |
Should the email show “as you” or “on behalf of you”?
We recommend that recipients can tell the email did not come straight from a person. Microsoft’s documentation on Exchange Online recipient permissions, as of October 2026, describes two delegate permissions for sending.
With Send on behalf, the From address “clearly shows that the message was sent by the delegate”. With Send as, the delegate can send messages “as if they came directly from the mailbox or group”. There is “no indication that the message was sent by the delegate”.
Microsoft describes these settings for people and accounts that act for a mailbox. In our view, the same thinking applies to an agent. Avoid letting it send from a person’s own mailbox. If it must, use Send on behalf rather than Send as. Otherwise give it a separate, clearly named sending address, such as a shared team address. That keeps the agent’s messages apart from a person’s own mail. It also gives you one place to review what went out.
What to set up first, step by step
Finish the test in step 5 before you widen anything.
- Pick one email type from the table, such as meeting confirmations.
- Give the agent its own sending address, not a person’s mailbox.
- Grant only what the job needs. Replying needs read and send permission, and meeting confirmations also need the calendar. Avoid any permission that can permanently delete mail. In OWASP’s example, an app that could read and send was tricked by an incoming email into forwarding data. So if the agent can both read the inbox and send, keep a person reviewing what it sends until testing shows no problems.
- Write down what it must never send, such as prices, refund decisions or anything about a legal matter. Instructions guide the agent but do not stop it. In Gmail, for example, permissions apply to the whole connection, not to each email type. So for risky email types, have a person send every one. For complaints, refunds and legal matters, a person writes them too.
- Test it on last month’s emails in draft mode. Compare each draft with what your team actually sent, and fix the instructions where they differ.
- Require a person to approve any send that commits the business. Set this up in your own process, so the agent prepares the draft and a person sends it.
- Review what the agent sent every week, including a sample of the full text.
- Widen to the next email type only when the review shows no problems.

Do spam and privacy rules still apply?
Yes. The rules that apply to you still apply when an agent sends for you. The Australian Communications and Media Authority (ACMA) covers marketing messages under the Spam Act 2003. Its guidance on avoiding spam, as of October 2026, says you must first have consent from the person who will receive them.
The ACMA also says that even if someone else sends your marketing messages, you must still have consent from each recipient. If someone else sends on your behalf, the message must still identify you as the business that authorised it. Every commercial message must contain an “unsubscribe” option.
The ACMA page is about marketing messages. Whether a given email counts as commercial is a legal question, so ask your adviser.
Privacy is a separate matter. The Office of the Australian Information Commissioner (OAIC) recommends that organisations do not enter personal information into publicly available generative AI tools. It calls this best practice, and names sensitive information in particular. That line is about publicly available tools. The wider guidance covers commercially available AI products, so read it before you connect a mailbox.
Where does Xagent fit?
Xagent is an enterprise agent platform by Xinference. Native connectors include Gmail and Outlook, and one trigger is a new Gmail message. Templates include email and inbox manager.
Every tool call and result is visible while a task runs, and a running task can be paused. A pause is not an approval step, so set approval up in your own process. You can save a task as an agent that keeps its role, model, tools and knowledge, then run it again or schedule it. Ask which permissions any tool requests before you connect it.
To see the Gmail and Outlook connectors in action, book a demo.
Questions
Can ChatGPT send emails for me?
Chat tools can draft an email for you. Sending needs a connection to your mail account with permission to send. Check your provider’s own documentation for what each plan supports.
Is it safe to give AI access to your email?
It depends on the access you grant. In Gmail, for example, sending and reading are separate permissions. Ask any tool which permissions it requests. Inbound email can also carry text meant to steer the agent, as OWASP describes.
Should the recipient know an AI sent the email?
We recommend yes. For commercial messages, the ACMA says the message must identify the business that authorised it. That rule is about naming your business, not about saying AI was used. In Exchange Online, Send on behalf shows which account sent the email.
Can an AI agent reply to emails automatically?
Yes, for narrow email types that you have tested. Keep a person on anything that commits the business to new prices, delivery dates or legal terms.
Do I need consent before an AI sends marketing emails?
Yes. In Australia, the ACMA says you must have consent before sending marketing messages, whoever sends them. Include an unsubscribe option in each one.
