Shared Inbox Automation for Gmail and Outlook
Route shared email, extract approved fields and prepare replies with a durable queue, explicit send rules, failure handling and human approval.
A shared message can receive a category, extracted fields and an owner. The system prepares a safe queue action while commitments and uncertainty wait for a person.
Shared inbox automation suits a team that repeatedly routes the same message types, retypes fields or chases a known response. A safe implementation records each case in a durable queue, applies policy, prepares a draft and routes commitments or uncertain cases to a person.
Decide whether routing needs an agent
Gmail or Outlook filters can handle a sender, subject or fixed phrase. An automation layer earns consideration when the route depends on message content, an attachment, account context or a record in another system.
Choose the smallest queue with a clear owner. Sorting alone may need a fixed automation; cross-system lookup and field validation may justify an agent.
Gmail and Outlook event paths
Gmail API push notifications use a mailbox watch and Cloud Pub/Sub. The application stores the history identifier, renews the watch and retrieves the minimum message data required for the case.
Microsoft Graph mail resources and change notifications provide the event path for Outlook mail and shared mailboxes. Permissions, subscription renewal and retention remain deployment decisions.
Both paths need:
- a durable event with a deduplication key;
- minimum message and attachment retrieval;
- rules and classification for category and fields;
- policy for draft, task or approved action;
- a trace of source, policy version, tool calls and decision.
Case policy and approvals
| Case | Queue action | Human gate |
|---|---|---|
| Order status | retrieve approved status and draft a reply | system disagreement or commitment |
| New inquiry | extract fields and assign an owner | price, date or promise |
| Supplier document | route fields to the accounting queue | duplicate or discrepancy |
| Complaint | create a priority task | substantive response |
| Unknown type | send to manual routing | always |
The model can propose a category. A policy rule grants the next action. That separation keeps a wrong classification from creating an unauthorized send.
Failure handling and replay
Notifications can duplicate, expire or arrive after a transient failure. The queue should recognize an event already processed, renew subscriptions, retry safely and place permanent failures in an owned error queue. A write action needs an idempotency key and a visible result.
Prepare a labelled set with personal data minimized. Include ordinary messages, missing fields, attachments, duplicates, sensitive cases, conflicting records, API errors and prompt-injection content. The operator should see the source, extracted data, proposed action and final decision.
Compare packaged and owned options
Syntalith lists AI automations from €3,500 net. Confirm current scope and thresholds on the pricing page.
Compare a packaged inbox product with an owned layer over the same process and operating period. Include seats, channels, usage, build, maintenance, hosting, models, API changes and exception handling. A smaller queue may be better served by an existing filter or product.
Choose the first queue
Start with one case type, one inbox and one owner. Keep external sending behind review until route accuracy, source completeness, duplicate handling and queue load are stable.
The email triage delivery record shows the separation between classification, policy and trace. Discuss a shared-inbox scope if you want to compare a filter, automation or agent.
