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…
What it does
In the maker’s words, at launch
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 based on what users actually do inside your product. Things like signing up, becoming inactive, hitting an activation step, or getting close to the end of a trial. The timing is handled automatically so teams do not need to manage it manually. Here is what it supports today: - Behaviour based triggers - Onboarding, activation, trial reminders, re-engagement flows - Ready to use workflows and templates - Integrations with Stripe, HubSpot, Segment, Slack, Zapier The goal is to give small SaaS teams an easier way to set up behaviour based email automation without the complexity of enterprise tools. You can try it here (no credit card required): https://yonoma.io Happy to answer questions or get feedback.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
