What a Fleece agent does with Gmail
Gmail is where your day arrives whether you want it to or not — customer questions, sales replies, invoices, receipts, notifications, and a long tail of threads that each need a small decision. A Fleece agent sits on top of the inbox and makes those decisions for you. It reads incoming mail, understands each thread in context, and acts: it drafts a reply, applies a label, files the message, extracts an attachment, escalates the urgent, or leaves it alone — according to instructions you give it in plain language.
Under the hood, the connection runs through managed OAuth — you authorize Gmail once, and Fleece handles tokens, scopes, and refresh securely. The agent can read and search messages using Gmail's own search operators, create and send drafts, reply within threads, apply and remove labels, mark read or archive, download and read attachments, and work across aliases and the accounts you connect. Event triggers let it react in real time the moment a new message lands or a label is applied — no polling, no delay.
What makes this different from Gmail filters or a canned template is judgment. A filter can only match a sender or a keyword and apply a fixed action; an agent reads the actual message, decides whether it matters, drafts an answer that fits the context, pulls in data from your other tools, and finishes the job. And because Fleece agents work as a hierarchy — a lead agent delegating to specialized child agents — one inbox-facing agent can hand research, data lookups, or scheduling to other agents and report back with a drafted reply ready for your sign-off.
What the agent can do in Gmail
Inbox triage
Reads incoming mail, classifies it by intent, and routes what matters — surfacing the urgent, archiving noise, and applying the right labels automatically.
Drafts replies in your voice
Writes context-aware drafts to recurring questions using your past threads and connected docs, ready to send or waiting for your one-click approval.
Labels, filters, and filing
Applies and removes labels, files threads into the right place, and keeps the inbox organized with judgment a static filter rule can't match.
Search and extract
Uses Gmail search operators to find threads and reads attachments — pulling invoice totals, order numbers, or contact details into your other tools.
Real-time triggers
Reacts the moment a new message arrives or a label is applied, through event-based triggers rather than polling, so nothing waits in a queue.
Approval gates
Anything sensitive — sending an external reply, forwarding, deleting — pauses for your one-click sign-off before it happens.
Automations teams run on Gmail
These are concrete setups you can describe to a Fleece agent in plain language. Each one combines Gmail with other connected apps.
Founders: an inbox that triages itself
The agent reads every incoming message, labels it by type, drafts replies to routine requests, and archives what needs no action. Genuinely urgent mail — a churn signal, a legal deadline, an investor reply — gets flagged and posted to Slack within seconds through real-time triggers. You open Gmail to a sorted inbox and a handful of drafts waiting for one-click approval instead of a wall of unread threads.
Support: shared mailbox to routed tickets
The agent watches your support alias, answers known questions in-thread from your documentation, and turns real issues into tracked work — creating a Notion page or posting to a Slack channel with the full thread and any attachments attached. It applies a status label in Gmail so the team can see at a glance what is handled, and escalates outage keywords to the on-call engineer immediately.
Sales: follow-ups that never slip
When a prospect replies, the agent reads the thread, updates the deal in HubSpot, drafts a contextual follow-up, and books time on Google Calendar when the reply asks for a call. Leads that go quiet get a gentle, well-timed nudge drafted for your approval. Every touch is logged to the CRM so the pipeline reflects reality without anyone updating it by hand.
Finance: invoices and receipts, extracted
The agent identifies invoice and receipt emails using Gmail search operators, reads the attachments, and extracts vendor, amount, date, and invoice number into a Google Sheets ledger. It labels each thread as processed, flags anything that looks off for review, and posts a weekly spend summary to Slack — so reconciliation is a glance, not an afternoon.
How to connect Gmail to Fleece AI
Create your Fleece account
Sign up and start the 7-day trial. You land in a workspace where agents, flows, and integrations live together.
Connect Gmail via managed OAuth
Pick Gmail from the integrations catalog and authorize it in one click. Fleece manages tokens and scopes for you; you can revoke access at any time from your Google account or from Fleece.
Describe the job in plain language
Create an agent and tell it what to watch and what to do — "triage my inbox, draft replies to known questions, label invoices and log them to Sheets". No flowchart building required.
Set autonomy and approval gates
Choose what the agent may do on its own and what waits for your sign-off. Sending external replies and deletions can pause for one-click approval.
Run it on triggers or a schedule
Let the agent react to new mail in real time, or schedule recurring flows — a morning triage pass, a weekly receipt summary — that run without you.
Gmail works better with the rest of your stack
Email automations get powerful when they cross app boundaries. Pair Gmail with Slack to turn urgent messages into instant channel alerts, with Notion to file support issues and decisions, with HubSpot to keep the CRM current as prospects reply, with Google Calendar to book meetings straight from a thread, or with Google Sheets to log invoices and receipts — all through the same agent, all under the same approval rules. Fleece connects to 3,000+ apps, so the stack you already use is almost certainly covered.
