Two SaaS exits. One very deliberate third act — George Hartley, Nitrosend
After scaling Bluethumb to $100M+ in artwork sold and SmartrMail to 6 billion emails sent before selling it in 2022 — George Hartley could have built anything. He chose email. And in this episode of SaaS Stories , he explains exactly why. This isn't a conversation about email for the sake of it. It's about why email remains one of the only channels you actually own, why the existing tools are structurally broken for the AI era, and what it looks like to build something from scratch when you've already done it twice before. We cover: → Why George came back to email after his second exit — and what he saw that nobody else was building → What's actually broken with legacy email platforms and why they can never fix it from the inside → How Nitrosend is built AI-native and MCP-first — and what that means in practice for your marketing stack → The 59,000-word open source email marketing guide George built for himself — and the three insights every SaaS marketer needs from it → Deliverability, list hygiene, send frequency — the stuff most people get wrong → The AEO lesson that cost them early traffic — why putting "beta" on your website is quietly killing your AI search recommendations → How getting approved as an official ChatGPT plugin sent their traffic through the roof overnight → The go-to-market channels that actually worked across two very different businesses — and what didn't transfer at all → The most honest founder advice we've heard on this show — pick people you can work with for 10 years, don't run out of money, and just don't stop If you're building in SaaS, running email for a growing business, or trying to figure out what go-to-market actually looks like in an AI-first world — this one is for you. 🎙️ SaaS Stories is brought to you by Hat Media — B2B marketing specialists for the SaaS world.
