What This Integration Enables

The Mailbox integration provides fundamental email capability: reading inbox contents, sending messages, and managing read status. It is the foundation for inbox monitoring workflows where agents watch for specific messages, process their content, and respond through the same mailbox.

Without FlowRunner

Manual inbox monitoring AP team opens the invoice inbox multiple times daily to check for new submissions

No content-based routing All incoming emails treated the same regardless of type or urgency

Sensitive emails missed Legal notices and compliance communications sit in a shared inbox unread

With FlowRunner

Inbox processed every 30 minutes New invoices extracted and queued before staff check the inbox

Automatic content classification Invoices, PO confirmations, and delivery receipts routed to different workflows

Immediate sensitive email alerts Legal and compliance content surfaced to the right manager within minutes of arrival

Use Case Scenarios

Dedicated AP Inbox Monitoring

The AP team has a dedicated invoices@company.com inbox. The agent polls Read Inbox every 30 minutes. For new messages with attachments, it extracts the attachment and sends it to Parseur for document processing. For messages without attachments, it sends an automated reply requesting the invoice document. Processed messages are noted. The AP team opens the inbox to resolved exceptions, not to read every incoming email.

Vendor Communications Processing

A purchasing inbox receives order confirmations, shipping notifications, and delivery receipts from vendors. The agent reads new messages, classifies them by content type, routes confirmations to the ERP, routes shipping notifications to the inventory tracker, and routes delivery receipts to the receiving team. Vendor email that used to be manually forwarded and tracked now routes automatically.

Customer Support Inbox Triage

A support inbox receives inquiries. The agent reads new messages, classifies them by type (billing, technical, general), and routes each to the appropriate Jira queue or Asana project. Simple inquiries receive automated responses. Complex ones are flagged for human response. The agent marks simple processed messages as read and leaves complex ones unread for the support team to see.

Human-in-Loop Highlight

When the agent reads an email that appears to contain a threat, a legal notice, or a compliance-sensitive communication (identified by keywords), it does not process it automatically. It marks the email as unread, sends an immediate Slack alert to the relevant manager: "Email flagged for immediate attention in [inbox]: [subject line] from [sender]. Contains possible [legal/compliance/complaint] content. Review now." The manager handles it personally. Sensitive communications have a human first reader.

Capabilities

Read Inbox Retrieves messages from the inbox using IMAP. Used in monitoring workflows where agents watch for specific senders, subjects, or content that should trigger downstream processing. An agent polls a dedicated inbox for vendor invoices, customer orders, or exception notifications at regular intervals.
Send Email Sends a message via SMTP from the connected mailbox. Used for operational notifications that need to come from a specific organizational address: a vendor confirmation from the AP inbox, a customer reply from the support mailbox, a notification from a dedicated operations address.
Mark Email As Unread Sets a message's read status to unread. Used in workflow coordination: when an agent reads a message to process it but the processing fails, it marks the message unread so it will be picked up on the next poll cycle. Also used to flag messages that need human follow-up.
