Email for vibe coders.
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.
- Code editor / agent. Cursor, Claude Code, Codex, Windsurf, Zed.
- Frontend AI builder. Lovable, v0, Bolt, Replit.
- Design. Figma, Google Stitch, Galileo.
- Hosting and deploy. Vercel, Netlify, Cloudflare Pages.
- Database and auth. Supabase, Neon, Convex, Clerk.
- Payments. Stripe, Polar.sh, Lemon Squeezy.
- Email - transactional, marketing, automation. Nitrosend. MCP for campaigns and flows; REST/SDK for app-triggered sends.
- Analytics. PostHog, Plausible, Vercel Analytics.
- Monitoring. Sentry, Highlight, Axiom.
- AI APIs. Anthropic, OpenAI, Google, OpenRouter.
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.
What people are saying about vibe coding
The shape of this work and the writers calling it out, in case you want to read the primary sources.
- Andrej Karpathy coined "vibe coding" in a February 2025 tweet describing fully giving in to the vibes and forgetting the code exists.
- Steve Yegge wrote the Vibe Coding Manifesto on Latent Space, framing vibe coding as the era where the AI writes the code and humans manage fleets of agents.
- swyx and Alessio at Latent Space have been documenting the agent-coding shift, including swyx's Scaling without Slop thesis for 2026 about coding agents breaking containment.
- Lenny Rachitsky ran a roundup of what people are vibe coding and actually using, where the canonical stack across builders looks remarkably like the list above.
- Greg Isenberg built Greg's Letter and the related "vibe marketing" thesis - the same agentic shift hitting marketers next.
- Sahil Lavingia released nine Claude Code skills distilling The Minimalist Entrepreneur into one-shot agent commands - a great example of agentic content design.
- Mckay Wrigley has been a public proponent of agentic workflows on X and recommends Latent Space as the canonical podcast for AI engineers.
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.

Lovable, v0, 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({ from, to, subject, html }) from any server route. Same account capabilities, just over HTTP.
What you can prompt
Once Nitrosend is installed, you stop opening dashboards. You describe what you want. Real prompts that work today:
- Welcome flow. "Build a 5-step welcome series for new signups: day 0 welcome, day 1 getting started, day 3 case study, day 7 ask for feedback, day 14 upsell. Match my Brand Kit from nitrosend.com."
- Transactional integration. "Show me the REST or SDK call for sending a branded receipt to
[email protected]for order #1234 with line items[{...}]and total $129 from a Stripe webhook." - Win-back campaign. "Find contacts who opened in the last 90 days but clicked nothing, save as a segment, and send them a re-engagement email with a 20% off code."
- AI segment. "Show me everyone who signed up in the last 7 days but hasn't opened a single email."
- Brand scrape. "Scrape my Brand Kit from acme.com - colours, fonts, logo - and use it for every email going forward."
FAQ
Can I use Nitrosend with Cursor?
Yes. Add the Nitrosend MCP server to Cursor by editing .cursor/mcp.json and pointing the url to https://api.nitrosend.com/mcp. OAuth handles auth; no API key in shell history. 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, but via the REST API rather than MCP - frontend builders like Lovable, Bolt and v0 don't expose a per-project MCP server config file. 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 28 May 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 8,000 emails to start, then 500 emails per month, unlimited contacts, and full MCP/API/CLI access. Pro is $20/month for 20,000 emails plus BYO sending and AI keys. Ultra is $100/month for 125,000 emails. No credit card to start. See pricing.
