Email for agents.
Email for agents.
Nitrosend is full-stack email built for AI agents. They sign up, onboard, send marketing and transactional email, spin up their own inboxes and talk to customers. Humans approve. Agents operate.
Sound
Point your agent at the skill
Skill <https://nitrosend.com/SKILL.md>Copy
It teaches the agent the whole platform, then walks it from signup to first send.
Connect from any agent
$ claude mcp add --transport http nitrosend https://api.nitrosend.com/mcpCopy
$ codex mcp add nitrosend --url https://api.nitrosend.com/mcpCopy
---
Then prompt:
"Read nitrosend.com/SKILL.md and onboard yourself. Create the account, connect our domain and send me a test."
Identity
Your domain, their address
Real addresses on the apex domain you own, [\[email protected\]](https://nitrosend.com/cdn-cgi/l/email-protection), not a subdomain workaround and not somebody else's domain. A verifiable identity your agent can sign up with and be reached at.
Conversation
Outbound and inbound
Agents read, search and reply over MCP. A customer answers at 3am, your agent handles it and triages the inbox before you even open it. Every thread stays searchable.
Escalation
Smart forwarding
The agent works the routine replies and forwards anything that needs a human to the right inbox. Approval gates sit exactly where you want them.
Coexistence
Plays nicely with Gmail
Every message, claimed or not, still forwards to the provider you already use. Your team keeps Gmail, Outlook or Zoho exactly as today; your agents get Nitrosend on the same domain.
Shipped
