Eliminate shared inbox chaos. AI agents classify, tag, and route incoming emails across departments without manual triage.
Shared inboxes don't scale. When billing inquiries, support tickets, sales leads, and partnership requests all land in one place, every team member sees everything and no one owns the response. Triage becomes a full-time job — and high-priority emails still get missed. The deeper problem is that routing logic lives in people's heads. It's inconsistent, it doesn't work nights and weekends, and it breaks whenever someone is on leave. Codifying that logic into a deterministic, auditable agent process is the only fix that holds.
MultiMail's multi-mailbox architecture lets AI agents implement consistent routing logic across your entire email operation. Agents call check_inbox on a shared mailbox, classify each message by department and priority using read_email content, stamp the original with tag_email, and forward to the correct destination via send_email — all in real time, with a complete audit trail. Routing rules live in code, not tribal knowledge. Monitored mode means your team sees every routing decision without approving each one, so the pipeline stays fast while staying observable. For VIP senders or escalations, switch to gated_send on those specific forwards to require human confirmation before the high-stakes message goes out.
The agent calls check_inbox on your shared mailbox to detect new arrivals, or you configure an inbound webhook to push new emails to your agent endpoint in real time. Webhook delivery eliminates polling latency for time-sensitive routing.
read_email returns the full message: body, sender, headers, and attachments. The agent passes this content to your classification logic — keyword matching, an LLM classifier, or a rules engine — to determine destination department and priority level.
tag_email stamps the message with routing metadata: department, priority, and routing status. Tags are queryable via the API, so you can audit routing decisions and build dashboards without a separate database.
send_email delivers the classified message to the target department mailbox — finance@, legal@, helpdesk@ — with the original content preserved. The agent prepends a routing summary so the receiving team has immediate context.
In monitored mode, your team has visibility into every routing decision without being required to approve each hop. For high-priority escalations or VIP senders, the agent routes those specific messages through gated_send, requiring explicit human confirmation before forwarding.
Pick your platform, copy the prompt, and paste it to your AI agent — it sets up MultiMail and builds the whole flow. Nothing to fill in.
Rules live in your codebase, not in people's heads. Version-controlled, testable, and consistent — the same logic runs at 3 AM on a Sunday as it does during business hours. Roll back a bad rule the same way you roll back any code change.
Every routing decision is recorded: which email was classified as what department, by which rule, forwarded where, and when. Tags set via tag_email are returned on every subsequent read_email call, so the full routing history follows the message.
Standard volume runs in monitored mode — zero approval friction, full team visibility. High-value senders and escalations use gated_send on those specific forwards. Oversight granularity is per-send, not a single account-wide toggle.
MultiMail accounts support multiple mailboxes under one API key. Create department-specific inboxes for finance, legal, sales, and support — each with its own access controls, storage quotas, and webhook endpoints.
Emails arrive once, get routed once, and land in exactly one place. The routing agent tags processed messages before forwarding, so re-runs are idempotent and team members only see emails that belong to them.
