I built hook2email.com, a tool that lets you send emails from a unique REST endpoint. Main uses (that I've found) are for notifications, low-code workflows, no-code tools, or quick integrations.
Why?
I often needed a simple way to get notified when something happens (new customer, error in production logs, deployment failed etc.).
I've been using it myself for a few years now, but only now released a front-end version
Would love feedback or feature ideas
Thanks!
