We started LuneaMail because we just wanted to send an invite email when someone registered in our app. Every tool we found was built for marketers first, and wiring a simple trigger meant digging through campaign builders and settings we didn't need. Making our own turned out easier. So now it does both: design an email once, send it from your app with one API call when something happens, or to a list as a campaign. Every send gets a spam check first. We launched in October and are looking for our first teams. What's the one email your app sends that's annoying to set up today?
