Email for vibe coders.

Updated May 8, 2026 · The AI-native email layer of the vibe coding stack

You've vibe-coded a SaaS in an afternoon. Auth is done, payments work, the dashboard ships. Then you go to set up email and the spell breaks. You're staring at Mailchimp's 47-menu dashboard or stitching together Resend for transactional, Loops for marketing, and a Mailchimp account you copy-pasted from someone's tutorial. Nitrosend is the email layer for the vibe coding stack. Add it once, then prompt campaigns and flows through MCP while your app sends transactional email through REST or the SDK.

$ claude mcp add --transport http nitrosend https://api.nitrosend.com/mcp

One command. OAuth handles auth. From here you ship.

The vibe coding stack - May 2026

Here's the stack vibe coders are actually shipping with right now. Some of these slots have one obvious winner; others have a few good options and the right pick depends on you. Where Nitrosend fits should be self-evident.

Resend is also a fine pick if all you need is a transactional API and you're happy to add Loops or Mailchimp later for marketing. Nitrosend keeps transactional + marketing + flows in one account and one bill: REST/SDK for app-triggered sends, MCP for campaigns, flows, contacts, and approvals.

The shape of this work and the writers calling it out, in case you want to read the primary sources.

Install Nitrosend in your editor

The MCP server is the same endpoint everywhere: https://api.nitrosend.com/mcp. OAuth handles auth in every supported client.

Cursor

Official plugin: run /add-plugin nitrosend in Cursor's Agent chat, or click Add to Cursor at cursor.com/marketplace/nitrosend. Manual alternative:

// .cursor/mcp.json
{
  "mcpServers": {
    "nitrosend": { "url": "https://api.nitrosend.com/mcp", "transport": "http" }
  }
}

$ claude mcp add --transport http nitrosend https://api.nitrosend.com/mcp

Claude Desktop / Cowork

$ codex mcp login nitrosend

ChatGPT

Add the official Nitrosend plugin from ChatGPT's plugin directory, click Connect and sign in. No config, no API key. It then works in ChatGPT on the web, desktop and mobile.

Windsurf, VS Code, Zed

See the integrations directory for client-specific install snippets.

v0

Nitrosend is one of v0's MCP presets: in a v0 chat, open the + menu in the prompt form, choose MCPs, then Nitrosend, and sign in. See the v0 guide.

Lovable, Bolt, Replit (REST, not MCP)

Frontend AI builders don't expose per-project MCP server config files yet. Use the REST API directly: npm i @nitrosend/sdk, then call ns.messages.send({ channel: 'email', to, subject, html }, idempotencyKey) from any server route. Same account capabilities, just over HTTP.

FAQ

Can I use Nitrosend with Cursor?

Yes. Nitrosend is an official plugin on the Cursor Marketplace: run /add-plugin nitrosend in the Agent chat, or click Add to Cursor at cursor.com/marketplace/nitrosend, then sign in. OAuth handles auth; no API key in shell history. You can also add the MCP server by hand in .cursor/mcp.json. Once installed you can prompt Cursor to build campaigns, wire up flows, and review tests. Use REST or the SDK for transactional app sends.

Can I use Nitrosend with Claude Code?

Yes. Run claude mcp add --transport http nitrosend https://api.nitrosend.com/mcp and Claude Code authenticates via OAuth. The MCP server gives Claude access to campaigns, flows, segments, contacts, tests, approvals, and deliverability. Use REST or the SDK for transactional app sends.

Can I use Nitrosend with Lovable, Bolt or v0?

Yes. In v0, Nitrosend is one of the MCP presets: open the + menu in the prompt form, choose MCPs, then Nitrosend, and sign in. Lovable and Bolt don't expose a per-project MCP server config file, so use the REST API there. Use @nitrosend/sdk from npm, or call api.nitrosend.com directly with a Bearer token. Same account capabilities, just over HTTP.

Is Nitrosend in beta?

No. Nitrosend is in production. Free and paid plans are both live now at app.nitrosend.com. Public launch announcement is May 28, 2026, but the platform itself has been operating with paying customers for months.

How is Nitrosend different from Resend for vibe coders?

Resend is a strong transactional API and also ships an MCP server. Nitrosend pairs a transactional REST/SDK path with a MCP surface for marketing campaigns, contacts, and multi-step automation flows. Contacts are unlimited on every plan, and you can BYO Resend (or SES, Postmark, Mailgun, SendGrid) keys for sending so you keep your existing deliverability reputation. See the full Nitrosend vs Resend comparison.

What does Nitrosend cost for vibe coders?

Free forever with 5,000 emails to start, then 500 emails per month, unlimited contacts, and full MCP/API/CLI access. Starter is $20/month for 20,000 emails plus BYO sending and AI keys. Pro is $50/month for 60,000 emails, Growth is $150/month for 200,000 and Scale is $300/month for 500,000. No credit card to start. See pricing.
