Email Triage Automation Workflow: Inbox to Actions
Email triage automation turns an inbox into a queue with decisions already made: every incoming message is classified (needs reply, FYI, task, meeting request, newsletter, spam), routine replies are drafted for approval, tasks and deadlines are extracted into your task tool, and what reaches the person is a short list ranked by urgency. It runs on shared inboxes (info@, sales@, ops@) and executive inboxes alike.

The problem
Shared inboxes are where requests go to be forgotten, and executives spend two hours a day deciding what an email is before doing anything about it. Replies to routine requests take days because they are queued behind hard ones.
What changes when it runs
Messages are answered or assigned within the hour. The inbox owner sees a daily digest: what was handled, what needs their decision, what was extracted as tasks. Routine requests get a drafted reply the same morning; nothing waits because it was invisible.
Trigger, then 8 steps
Trigger
Gmail / Outlook trigger (new message)
Polls the mailbox every minute for new messages via Gmail or Microsoft Outlook triggers; threads are handled as a unit.
Receive and de-duplicate
Gmail TriggerNew messages and thread updates; automated notifications and newsletters are recognised by sender patterns and handled by their own rules.
Classify
Text ClassifierIntent (reply needed, task, meeting request, FYI, invoice, complaint, spam), urgency, and the internal owner if the inbox is shared. Rules for known senders override the model.
Fetch context
HTTP RequestCRM record for the sender, open tickets or deals, prior thread history, and the calendar for meeting requests.
Extract tasks and dates
Information ExtractorAny request with a deliverable and a date becomes a structured task with owner and deadline; ambiguous ones are flagged for confirmation.
Draft routine replies
AI AgentFor categories with an approved playbook (pricing questions, scheduling, document requests, status updates) the agent drafts a reply in the owner's voice, grounded in the context fetched.
Route
SwitchDraft to the owner for one-click approval; tasks to Asana/Linear/Notion; meeting requests to a scheduling link or calendar hold; invoices to AP; complaints straight to a person with the thread summarised.
Approve and send
WaitDrafts sit in a Slack or Gmail 'ready' label; approval sends from the owner's address. Nothing is sent without a click unless a category has been explicitly set to auto-send.
Daily digest
Schedule TriggerOne message at 8am: handled, waiting for you, extracted tasks, and anything the classifier was unsure about.
Data it touches
- Mailbox (Gmail, Google Workspace, Microsoft 365)
- CRM contacts and deals
- Calendar
- Task tool (Asana, Linear, Notion, ClickUp)
- Reply playbooks per category
Guardrails
- Drafts require approval by default; auto-send is enabled per category by the inbox owner and logged.
- Complaints, legal, HR and anything from unknown senders with attachments go to a person unread by the agent's reply logic.
- The agent never invents facts about availability, pricing or commitments; it drafts from the context fetched or asks.
- Every automated action is visible in the thread and the digest.
Classification is where the time goes
Reading an email to decide what it is takes almost as long as dealing with it, and it happens for every message. The classifier does that once, reliably, and attaches the decision to the thread — so the person opens an inbox that is already sorted into 'needs me', 'drafted for you', 'done' and 'noise'. That alone recovers an hour a day for most people who run a busy inbox, before any reply is drafted.
Which replies to automate
Start with the ten most common routine requests the inbox receives — you can find them by classifying a month of history — and write a playbook for each: what the reply should contain, what context to pull, what it must never promise. The agent drafts within those playbooks. Everything else gets a summary and a suggested action, not a draft. Expanding the playbooks over time is how the automation rate climbs without the risk climbing with it.
Executive inboxes
For an executive the same workflow runs with a stricter posture: nothing auto-sends, the digest is the primary interface, and the assistant (human or agent) works from the classified queue. The extracted-tasks step is the most valued part — commitments made in email finally land in the task system with a deadline, instead of in memory.

Frequently asked questions
Does the agent send emails on its own?
Not by default. Every draft is approved with one click. The inbox owner can enable auto-send for specific low-risk categories once the drafts have proven reliable, and those sends are logged.
Will it work with our CRM?
HubSpot, Salesforce, Pipedrive and Attio are supported for sender context and logging. Without a CRM the workflow still classifies, drafts and extracts tasks.
How does it handle attachments?
Invoices go to accounts payable with the data extracted; documents are summarised for the digest; anything unexpected from an unknown sender is flagged, not opened by the reply logic.
