Email for AI agents. They sign up, send and reply.
Nitrosend is full-stack email built for AI agents. Point any agent at nitrosend.com/SKILL.md and it signs itself up, onboards, connects your domain and sends. Live today: marketing and transactional email, real inboxes for agents on your own domain (beta, by request), and 1-1 customer replies with human escalation. Coming soon: personalised outreach run by your agent. In development: goal-based agentic marketing. Humans approve. Agents operate.
Nitrosend came out of running Obooko (producthunt.com/products/obooko, #2 Product of the Day here in February). Running a free ebook platform with 840,000 readers on its list, entirely through an AI agent, convinced me the dashboard era of email is done. It's also my third email company: SmartrMail (acquired 2022) and Sendicate before it, with six billion emails sent between them.
Six weeks ago we launched Nitrosend as headless email you run from Claude or Codex instead of a UI. Today it goes further: the agent gets an inbox, and get send for itself. Point any agent at nitrosend.com/SKILL.md and it signs up, connects your domain, sorts billing and sends its first email. no human required.
The bit I'm proudest of is Agent Inboxes (beta): real addresses for your agents on the domain you own, created BY your agent, like [email protected], [email protected]. They send, receive and hold 1-1 conversations with your customers, and escalate to a human when it matters. Gmail actively fights this. we built the place where it's native. Because very soon this will be table stakes for your agent, so we're shipping it now.
Coming real soon: Agentic Outreach, where your agent researches prospects, writes personally and works the replies. Get a look alike audience from your current customer list, zoom in on your ICP, give them personalised messaging. No start up founder I know likes doing spray and pray outbound, but some still do it as the tools aren't good enough to really make it relevant. We're solving that.
In development: set a goal for your brand's email and Nitrosend does the rest.
Agentic signup and onboarding are shipped, headless full stack newsletters, flows, transactional email all live sending and delighting our first users (including me on Obooko!). Agent Inboxes are beta by request (ask in app and we can turn it on for you), Outreach is coming soon, goal-based is in dev.
Super excited to ship this, ask any question in the comments!

Who hunted Nitrosend?
Nitrosend was hunted by George H.. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
