Description

Nitrosend is an AI-native email platform for campaigns, automated flows, newsletters and transactional email. You can run it from Claude, ChatGPT, Cursor, Codex or any MCP client, from your own code through a REST API and TypeScript SDK, or from its dashboard. It was built by George and Edward Hartley and Kam Low, the team behind the Shopify email tool SmartrMail.

There is a free plan with 5,000 starter emails, then 500 a month, with no card. Paid plans start at $20 a month for 20,000 emails, or $192 a year, and every plan includes unlimited contacts (checked 13 November 2026). Full desk review: Nitrosend review 2026.

Evidence caveat: Nitrosend launched publicly in June 2026, so it is young. Its seed round was reported by Startup Daily and InDaily, but usage figures on its site and in founder posts, such as “94% of actions” happening inside an agent and weekly volume growth, are Nitrosend’s own claims.

Who Nitrosend Is For

  • Agencies running email for several clients, each with its own brand kit, sending domain and client-owned account.
  • Founders and lean marketing teams who already work in Claude or ChatGPT and want campaigns and flows drafted there.
  • SaaS and developer teams who need marketing and transactional email from one provider, triggered by product events.
  • Shopify and online stores wanting product launches, order confirmations and post-purchase flows.

Core Capabilities

Email From Your AI Agent

Nitrosend’s first-party MCP server exposes 28 tools for campaigns, automation flows, contacts, segments, templates, test sends, approvals, deliverability and analytics. OAuth sign-in works in Claude Code, Claude Desktop, ChatGPT, Cursor, Codex, Gemini CLI and other clients. Live sends to an audience still pass through a human approval step.

Flows Built From Your Website

Give it your website and a goal and it suggests starter flows, such as welcome, activation and win-back, then drafts the first email in your brand for you to edit and test. Nothing sends until you review and switch it on.

Transactional Email and Events

A REST API, a TypeScript SDK, a CLI, webhooks and an events endpoint let your app send receipts and trigger flows from custom events. You can also bring your own sending keys for Resend, Amazon SES, Postmark, Mailgun or SendGrid.

Multi-Brand Workspaces for Agencies

Brand kits, separate sending domains and client-owned accounts let an agency build each client’s emails in that client’s brand and hand over ownership while staying on the team.

Pros & Cons

Pros

  • Unlimited contacts on every plan, so you pay for sending, not list size.
  • A genuinely agent-first design: MCP, API, SDK and CLI are all included.
  • A usable free plan and clear public prices.

Cons

  • A young email service provider, launched publicly in June 2026.
  • Daily sending limits depend on “sender standing”, so new accounts start lower.
  • Most traction figures are self-reported.

Where Nitrosend Fits

Nitrosend sits with AI email marketing tools and marketing automation tools. If you want a long-established ESP instead, compare it with Klaviyo or Mailchimp; for AI cold outreach rather than permission email, see Swokei. Browse the full AI tools directory.

FAQs

Can I use Nitrosend from Claude or ChatGPT?

Can an AI agent send to my whole list without me?

Nitrosend says live audience sends require confirmation through its approval step. Test sends and individual transactional emails do not wait for it.
