AI agents for Gmail
A Monmo agent works in Gmail the way an assistant with your inbox open would. It sorts what arrived overnight, tells you which messages need you, drafts replies in your voice, finds old threads and chases the ones nobody answered. It connects to your own Gmail account, reads on the schedule you agree, and asks before it sends, archives or deletes anything.

What agents do in Gmail
Sort the morning inbox
Every weekday at 7:30 the agent reads what arrived overnight and sorts it: needs you, for information, safe to archive. You get the three or four messages that need a decision, each with one line of context.
AskEvery weekday at 7:30, go through my inbox and tell me what needs me today. Ask before you archive anything.
Draft each reply the way you write
For each message that needs an answer it reads the whole thread, checks the calendar or the attachment the answer depends on, and writes a reply in your voice. You change what you like, then allow the send.
AskDraft replies to the five emails I starred this morning. Keep each under 120 words and use my usual sign-off.
Find a thread and say what was agreed
Ask about a customer, an invoice or a decision. The agent searches your mail, reads the full thread and its attachments, and tells you who agreed what and on which date, with the message it came from.
AskFind the thread where Northwind agreed the March delivery date and tell me exactly what was promised.
Chase the replies that never came
It keeps track of the messages you sent that nobody answered. After the number of days you set, it drafts a short nudge for each, quoting the original question, and asks before any of them goes out.
AskEvery Thursday at 4, list emails I sent more than five days ago that got no reply, and draft a follow-up for each.
Answer a shared support address
When mail arrives at an address such as support@, the agent sorts it by topic, checks the order in your other apps and prepares the replies. Routine answers go out on one approval; complaints come to you.
AskWhen an email arrives at support@, draft a reply from our returns policy and ask me before sending. Complaints come straight to me.
Turn a request into a calendar change
A customer asks to move Thursday from 2 PM to 3 PM. The agent checks Google Calendar for clashes, drafts the reply confirming the new time and, once you allow both, sends it and moves the event.
AskJamie wants to move Thursday's call to 3 PM. If I'm free, draft the reply and update the event.
Collect invoices and attachments
Invoices, order confirmations and booking emails hold figures you need elsewhere. The agent finds them, saves the attachments and lists supplier, amount and due date in a spreadsheet, with a link back to each email.
AskFind every invoice emailed to me in October and list supplier, amount and due date in a spreadsheet.
Clear out newsletters you never open
It counts what each sender mailed you in the last 90 days and how many you opened, then proposes what to archive and which lists to leave. One card covers the whole clean-up, and you can untick any sender.
AskShow me which newsletters I haven't opened in three months and propose what to archive.
How it connects
- 1You sign in to your own Gmail or Google Workspace account once. The agent works in the mailbox that account can open, and connecting it does not start any reading on its own.
- 2Your mailbox is open only to the agents you pick. Your Chief of Staff or a support agent needs it; an engineering agent usually does not.
- 3Reading, searching and drafting need no approval. Sending, archiving, labelling or deleting asks first, and one card can cover a batch of replies.

Questions people ask
Can an AI agent manage my Gmail inbox?
Yes, up to the point where something leaves your mailbox. A Monmo agent reads your inbox on a schedule you agree, separates what needs you from what does not, drafts replies and tracks follow-ups. Sending, archiving and deleting each show a card first, and one card can cover a batch such as eleven replies.
Will an AI agent send emails from my Gmail without asking?
No, sending always waits for you. Before any email goes out, the agent shows a card with the recipient, the subject, the full text and the reason. You can edit the draft, allow it or decline it, and a declined reply is not sent. Reading and drafting are the parts it does without asking.
Is it safe to give an AI agent access to my email?
A Monmo agent uses the Gmail account you connect and can see only what that account can. Connecting does not start anything: it reads mail when you ask, or when a routine you agreed runs. You can watch its screen while it works, limit Gmail to certain agents, and disconnect the account whenever you choose.
Can an AI agent work with Google Workspace and shared inboxes?
A Monmo agent works with the Gmail or Google Workspace mailbox you sign in to, and with a shared address if you connect the account that owns it. Some organisations limit outside apps, so an administrator may have to approve the connection first. If a step is not covered by the Gmail connection, the agent can open Gmail in its own browser and do it there.
