Nitrosend

Nitrosend provides agents with email infrastructure for sign-ups, onboarding, marketing, transactional emails, inbox management, and customer replies.

What is Nitrosend?

Nitrosend is a full-stack email infrastructure built specifically for AI agents. It handles sign-ups, onboarding, marketing, transactional emails, inbox management, and customer replies—all from a single URL. Agents can self-onboard without human intervention, using OAuth, vocabulary, tools, and safety gates. No API key or dashboard is required; you simply point your agent at a skill file that teaches it the entire platform.

Application scenarios

  • Agent self-onboarding

    AI agents create accounts, connect domains, and send their first email with zero human steps.

  • Inbound customer support

    Agents receive replies, confirmations, and support threads directly in their own inboxes on your domain.

  • Outbound outreach

    Agents research prospects, write personalized emails, send sequences, and handle replies.

  • Marketing campaigns

    Agents run goal-based email marketing for your brand, planning and executing campaigns.

  • Transactional email

    Agents send automated transactional messages like sign-up confirmations and order updates.

  • Inbox triage

    Agents read, search, and reply to customer emails overnight, triaging inboxes before humans wake up.

Core Features

  • Agentic signup & onboarding

    Your agent creates the account, sorts billing, and sends its first email without any human steps.

  • Real inboxes on your domain

    Agents get [email protected] addresses on your apex domain, not a subdomain workaround.

  • MCP-based conversation

    Agents read, search, and reply to emails over the Model Context Protocol, keeping every thread searchable.

  • Smart forwarding

    Agents handle routine replies and forward anything needing human attention to the right inbox.

  • Approval gates

    You place approval gates exactly where you want them, so agents operate within your boundaries.

  • Gmail coexistence

    Every message still forwards to your existing provider (Gmail, Outlook, or Zoho), so your team keeps their current workflow.

  • Agentic outreach (coming soon)

    Agents research prospects, write like a person, send in sequence, and escalate what matters.

  • Agentic goal-based marketing (in development)

    Set a brand email goal, and Nitrosend plans and creates the campaign.

Target users

AI agent developers and operators who need their agents to handle email autonomously. Also useful for teams running multiple AI agents that require distinct, verifiable email identities on their own domain—perfect for support, sales, and marketing automation roles.

How to use Nitrosend?

Point your agent at the skill file at https://nitrosend.com/SKILL.md. The agent reads it, learns the entire platform, and walks itself from signup to first send. You can also connect via MCP: use $ claude mcp add --transport http nitrosend https://api.nitrosend.com/mcp or $ codex mcp add nitrosend --url https://api.nitrosend.com/mcp. Then prompt your agent to read the skill file, create an account, connect your domain, and send you a test email.

Effect review

Nitrosend solves a genuine pain point: AI agents are often blocked by aggressive bot detection from Gmail and Microsoft, and they can't hold their own email addresses. By giving agents real inboxes on your apex domain with full MCP support, Nitrosend makes agentic email practical. The self-onboarding workflow is particularly strong—committed users already run it daily with zero human steps. While inbound inboxes are still in beta and outreach features are coming soon, the core infrastructure is solid and ready for production use.
