Three steps. No dashboard required.
nitrosend speaks MCP natively. Your AI tools connect directly to the platform.
Connect
One command. nitrosend connects to Claude, ChatGPT, Cursor, Gemini, wherever you work. No new interface to learn.
Prompt
Tell it what you need. "Create a 5-email onboarding series." "Send a product update to active users." It builds it.
Ship
Your email runs. The AI monitors performance, tests improvements, and optimises automatically. You get back to building.
Full-stack email. Zero busywork.
Minutes, not months
Set up transactional email, welcome flows, campaigns, and automations faster than any other platform. Because the AI does the work.
Works where you work
Claude Code, Claude Desktop, ChatGPT, Codex, Cursor, Gemini. nitrosend plugs into the tools you already use. No context-switching.
Transactional + marketing
One platform for password resets AND newsletters. One API for everything. Most tools make you choose. We don't.
Gets smarter every send
Every open, click, and reply teaches the system. Subject lines, send times, content, all continuously optimised without you lifting a finger.
Bring your own keys
Want to use your own SendGrid, Postmark, SES, or Resend for sending? Your own Anthropic or OpenAI keys for AI? Full control, no lock-in.
Unlimited contacts. Always.
Never pay for contacts you're not emailing. Pay for what you send. Your list grows? Your bill doesn't.
WindsurfWindsurfPixel-perfect email design.
AI-driven visual design that matches your brand from day one. Modern templating, beautiful defaults, and full creative control — whether you design from Claude or code it yourself.
Auto-detects your brand colors, fonts, and logo. Every email looks like it came from your team.
Describe what you want. Get production-ready email templates in seconds, not hours.
Responsive, accessible, dark-mode ready. No more fighting Outlook rendering bugs.
Enterprise grade email infrastructure.
When you embed an email provider in your stack, you're trusting them with your customer relationships. We know what that means. We've been on both sides.
Enterprise-grade sending infrastructure that processes 700B+ emails per year.
Transactional and marketing emails run on separate infrastructure. Your password resets never compete with your newsletters.
DKIM, SPF, and DMARC configured automatically. Dedicated IPs available. Auto-warmup included. Sender reputation protected from day one.
It's our third rodeo.
Between us we've built two email platforms, sent over 6 billion emails, and exited three companies. We've been on both sides of the email stack: building the tools and using them to grow real businesses.
Kam built SmartrMail as CTO. 12,000 customers, 6 billion emails, the highest-rated email automation app on Shopify, acquired by Relay Commerce in 2022. Ed founded Sendicate, one of the first design-led newsletter platforms, with 28,000 users. George and Ed co-founded Bluethumb, Australia's largest online art marketplace, and served as Co-CEOs until exiting in late 2025.
This isn't a side project. We've spent a decade in email infrastructure and we're building nitrosend because the world has shifted and email tools haven't caught up.
