Ummm google forms? It’s free and will dump into a google sheet. (Haven’t looked to see if I can see what your form was to know if I’m making a dumb recommendation or not.)
Lol yeah I was using sheet.best because I thought it was the simplest possible solution - literally just a POST endpoint for a google sheet, it’s pretty good. Airtable is a good shout, but I should probably pick something that actually sends emails because I’ve been putting it off forever lol
