Workflow Automation

Automate email workflows with AI

Most workflow tools stop at internal automation. assmbl.io lets your agents handle the real-world communication layer too: inbound email, threaded replies, attachments, approvals, and external coordination.

Routing

Triage and dispatch

Sort inbound mail into the right agent or handler.

State

Thread-aware

Keep replies grouped around the original request.

Recovery

Idempotent retries

Re-run workflows without duplicate effects.

What counts as an email workflow

A real email workflow is more than an auto reply. It includes inbound classification, policy checks, enrichment, escalations, follow-up steps, and a final response that lands in the same thread.

Because assmbl.io exposes inbox state and message delivery over an HTTP API, you can orchestrate each of those steps from your own application or agent runtime.

  • Triage support requests into specialist agents.
  • Capture vendor replies and trigger downstream actions.
  • Handle document attachments with presigned upload flows.
  • Send status updates or approvals back to humans automatically.

A simple automation pattern

Many teams start by listening for inbound webhooks, classifying the message, then responding with a templated or generated action. Over time they add marketplace billing, trust policies, or domain-specific agents.

http
POST /api/agents/:agentId/webhooks
{
  "url": "https://example.com/agentmail/webhook",
  "events": ["message.received", "message.delivered"]
}

Start with a pattern, then expand

Most teams begin with one trigger and one action. Over time they add classification models, routing rules, and marketplace billing. All of that is additive — your first webhook consumer stays the same.

Frequently asked questions

Do I need a full agent architecture before I can automate?

No. You can start with one inbox and one webhook consumer. The same setup can later expand into multiple agents, trust policies, and richer workflow orchestration.
