Nitrosend

What is Nitrosend?

Nitrosend is a full-stack email platform built from the ground up to be operated by AI agents rather than through a conventional web dashboard. Instead of bolting AI features onto legacy email software, Nitrosend was designed MCP-first, meaning agents such as Claude, ChatGPT, Codex, Cursor, and Gemini can write copy, design templates, segment audiences, run A/B tests, and send campaigns purely through natural-language prompts. The platform covers both marketing email (campaigns, automations, newsletters) and transactional email (via REST API and Node SDK), all under a single account with unlimited contacts and pay-per-send pricing that removes the per-contact fees common in legacy email tools.

Key Features

• MCP-First Architecture

  Native Model Context Protocol support lets Claude, ChatGPT, Cursor, Codex, Gemini, Windsurf, VS Code, and Zed control the entire email stack through a single install.

• Agent-Run Campaigns with Human Approval

  AI agents draft, design, segment, and schedule campaigns while founders or teams retain approval gates before anything goes out to subscribers.

• Unlimited Contacts, Pay-Per-Send

  Every plan, including the free tier, includes unlimited contacts, so pricing scales with email volume rather than list size.

• Multi-Brand Management

  Higher-tier plans support managing five or unlimited separate brands from one account, with sending volume pooled across the whole account.

• Transactional Email API

  REST API and Node SDK give developers programmatic control over transactional sends, with bring-your-own sending keys available on paid plans.

• Built-In Email Infrastructure

  Founding team brings a decade of email deliverability experience, packaged into automations, templates, contact management, and analytics available on every plan.

Use Cases

• AI Agent Email Automation : Developers building AI agents or SaaS products can give their agents the ability to sign up users, send onboarding flows, and manage inboxes autonomously.
• Vibe Coding Workflows : Solo builders and 'vibe coders' can add email marketing to a project by prompting Claude or Cursor instead of learning a separate email tool.
• Agency Multi-Client Campaigns : Marketing agencies managing several client brands can run and pool sending across multiple brands from a single Nitrosend account.
• Transactional Notifications : Development teams can integrate the REST API or Node SDK to send receipts, password resets, and other transactional emails directly from their codebase.
• Newsletter and Drip Campaigns : Content creators and SaaS teams can generate, test, and send newsletters or automated drip sequences by describing them in natural language.
