Hey Product Hunt, George here 👋🏻
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 ernest@yourcompany.com, sylvia@yourcompany.com. 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!

Tried it out and sent an email from Claude in about 3 minutes. Pretty useful, I'm not a fan of logging into a clunky dashboard just to send an email when everything else is via API/MCP.

@jgdeutsch love that Jeff. 3 mins though, we gotta improve those numbers hahah. And yeah, who needs dusty UIs these days?!
@jgdeutsch @gthartley I think you should add features that make a user not even feel the time they spend there, because if I have to login on a dashboard just for my AI agent to send an email instead of doing it proactively in the background, it gets annoying. Love the vision though, but still needs some more planning.
Congrats @gthartley for the launch 🙌 love the target audience lookalike concept for outbound, qq how do you handle privacy and security for AI-managed conversations?
Finally a sane way to let agents handle email without me babysitting every send. Pointed one at the SKILL.md file and it had my domain sending in minutes, which honestly surprised me.
