Yonoma – Behavior based email automation for SaaS
Hi HN, I've been building Yonoma (https://yonoma.io), an email automation tool focused on early stage SaaS teams. I used a few well known tools in this space while working with other SaaS founders, and I kept seeing the same problem. These tools are powerful, but they are also built for larger companies. Setting up simple onboarding or trial reminder flows often felt heavier than it needed to be. Many founders told me they wanted something easier that still reacts to how users behave inside the product. So I tried to build something simpler and more focused. Yonoma sends emails…

Migma AI2025 · migma.ai · ▲483After our email campaign generated 30% more revenue at my previous startup, I knew we needed to double down on email marketing. Problem was, our workflow was absolutely broken: - Designer in Figma (day 1-2) - Copywriter with ChatGPT (day 2-3) - Developer to code it for 40+ email clients (day 3-5) - Back and forth for revisions (day 6-7) - $1500+ per campaign, weeks of delays I built Migma.ai to solve this. You paste your website URL, describe what you want ("announce our new feature using info from this blog post"), and get a complete, on-brand, responsive email in 30 seconds. Migma: -…
Zero2025 · 0.email · ▲845Hi HN, I’m Nizar, and I’m building Zero (https://0.email) — an AI-powered email client that manages your inbox for you. Email hasn’t changed in decades, even though the way we work has. The average knowledge worker now spends close to 30% of their week on email, constantly reacting, replying, and sorting through noise. It’s become one of the biggest productivity sinks in modern work. At the same time, AI has transformed how we write, plan, and collaborate — yet our inboxes are still stuck in the past. I built Zero to fix that. Zero automatically prioritizes, organizes, and even…
Sidemail 2.0Nov 2025 · sidemail.io · ▲306Hi all! I'm Kristyna, maker of Sidemail. I'd love to share with you what we've been building. We built Sidemail because sending emails from a SaaS app was way harder than it should be. Sidemail is made for developers and teams that want one simple place to handle SaaS emails with reliable delivery and no bloat. It has: - Everything for creating, managing and delivering SaaS emails in one platform, - Easy-to-use email API for sending password resets, receipts, etc. - Messenger for writing product updates and newsletters, - Email automations for onboarding and lifecycle flows, - Fast email…
Talanoa21d ago · talanoa.email · ▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

YansuMay 2026 · yansu.app · ▲338Hi HN Most teams run on a dozen SaaS tools and use maybe 20% of each. The rest is someone else's workflow that you're paying for. We built Yansu to fix that. It learns how you work — your desktop, your Slack, your Teams — and proactively builds bespoke tools tailored to you. You don’t need to prompt. It sees a pattern, builds a solution, and surfaces it for you to use or toss. Like, I do the same things before every call: look through Linkedin, see any open threads on email, read the latest blog/news of the company and any relevant slack conversations. Yansu noticed and built me an app…
