AgentMail

AgentMail Integration

AgentMail is email infrastructure built for AI agents and modern email applications. Provision inboxes, manage custom domains, and send + receive email programmatically via API with first-class deliverability, webhooks, and observability.

With the AgentMail + Vercel integration, you can attach a real email identity to your Vercel projects in seconds.

What Can You Build?

• Voice agents that receive and respond to emails in real time
• Browser agents that self-authenticate using email-based 2FA
• Document-processing agents that ingest attachments and reply automatically
• Human-in-the-loop agents that CC teammates for review and approvals
• Autonomous workflows that trigger actions from inbound emails

Agentmail exposes webhooks for all email events (such as messages sent, received, bounced, etc), allowing your Vercel functions and agents to react automatically as email state changes.

For real-time use cases, AgentMail supports websockets to stream live email activity and metadata.

AgentMail also supports custom domains and inbox provisioning via API, so you can create isolated inboxes, assign domains, and manage email identities programmatically.

Attach custom labels and structured metadata to messages and threads to give your agents richer context. Use labels to classify intent (e.g. support, invoice, urgent), route workflows, store agent state, or pass signals between tools without re-parsing email content.

AgentMail also supports multi-tenant architectures via pods, allowing you to isolate inboxes and domains per tenant when whitelabeling AgentMail to your customers.

All features are API-first and designed to plug cleanly into event-driven Vercel applications.
