I just switched over to it from proton. Do not have the issue that their spam filter is abysmally bad? There is so much spam coming though and even mails that I already reported as spam come through. Also the app is kinda slow and clumsy.

Baserow or nocodb come to my mind. They are actually airtable alternatives but also include a forms feature

I play an Irish sport called hurling and I am neither Irish nor I am in Ireland. So nobody knows this sport so I have to explain a lot what it is. But it is so much fun!
