Give Vercel agents their own inbox with AgentMail

AgentMail is an email-infrastructure tool for Vercel apps that need real inboxes for agents, assistants, and workflow automation. It is useful when an agent must receive attachments, handle email-based verification, route support messages, or keep a human reviewer in the loop without sharing one generic mailbox.

The Vercel Marketplace page lists AgentMail as a native integration for provisioning inboxes, managing custom domains, and sending or receiving email programmatically. The product page adds the practical developer angle: the TypeScript SDK works in Next.js API routes, App Router route handlers, serverless functions, and Edge functions.

Best fit

• AI support agents that need a dedicated inbound address.
• Browser or workflow agents that must handle email-based login checks.
• Document-processing flows that receive attachments and reply automatically.
• Multi-tenant SaaS products that need one inbox per user, tenant, or agent.

Check before building

1. Confirm pricing, limits, and Vercel Marketplace billing for your account.
2. Use separate inboxes and domains for tenants or high-risk workflows.
3. Validate webhook signatures and keep retries idempotent.
4. Treat inbound email and attachments as untrusted input before handing them to an agent.
5. Add human review for workflows that can send external replies or trigger account changes.
