Netlify form does not work if a specific email adress is put in the form

[Melvin]

Hi @Masahero0123,

I see a similar question with a solution posted here:

Form submissions from people with single email domain marked as spam

for anyone running into this issue in the future, I’ve created a quick and dirty node script (run as netlify function) that uses the netlify forms api to get spam submissions, checks the email and marks it as not spam in case it’s a ‘clean’ email. (it’s not taking the api rate limiting into account as I’m not expecting any issues with my site)

Maybe this workaround will help you?
