Nitrosend is headless email marketing from inside your AI agent. Connect Nitrosend in Claude, Codex, ChatGPT or any agent, then run email flows, newsletters and transactional emails from a prompt.
codex mcp add nitrosend --url https://api.nitrosend.com/mcp, then codex mcp login nitrosend.
If you'd rather click than prompt, the dashboard walks you through the same install.
Add your sending domain ([email protected]) and paste the three DNS records. Most domains verify in under a minute. Or skip and send from a free Nitrosend subdomain.
Upload a CSV, paste a list, or sync from Attio, Stripe or your product. Unlimited contacts on every plan.
Describe the email you want. Our AI drafts subject, preheader, copy and design in your brand. Edit visually or prompt it to iterate.
Preview light and dark mode, send a test, then hit send. Opens, clicks, replies and unsubscribes stream back live.
