Resend Launches Agent-Focused Inboxes and Its Own Mail Infrastructure Forge
At the Forward conference, email service Resend announced two products: Resend Inboxes, an inbox product for AI agents and humans, and Forge, email infrastructure the team built from scratch. This marks Resend's expansion from a developer email-sending service into the new direction of "agent-native email."
Confirmed
- Resend Inboxes is positioned as "The Inbox for Agents," serving both "humans and their agents"
- Four integration options: a polished UI, API, CLI, and an MCP server, letting agents directly read and write email inboxes
- Agents can connect to users' existing agent frameworks via MCP or skills
- Supports creating multiple inboxes to organize email (e.g., domain verification, billing)
- Human-agent collaboration: agents and humans can reply within the same email thread, seamlessly
- Forge is mail infrastructure built in-house by the team, positioned as a fast, self-controlled foundation that removes dependence on third-party infrastructure
Why it matters
- As AI agents see mass adoption, email is becoming a key channel for agents to interact with the outside world; Resend is moving early with "agent-native inbox" capability, paving the way for agents to have their own identities and email addresses
- The built-in MCP server means mainstream agent frameworks can send and receive email plug-and-play, lowering the barrier for agents to plug into real-world workflows
- Building Forge in-house shows Resend starting to vertically integrate its email delivery stack, potentially improving delivery speed and controllability — and directly competing with existing email infrastructure vendors
