Block specific email domains: We're getting a lot of sign ups from protnmail, simplelogin, suremail, mailbit, passinbox, 8shield, and other secure or temporary email services that lower the quality of our users. Is there a way to set a list of "do not allow" email domains for email sign up? I know a lot of sites do detection on the email domain during signup to make sure you're using a "good" email. It would be better if there were some sort of proactive feature to signal email address "quality" during signup, but a s imple "do not allow" list would probably do the trick at least for now. Though there are hundreds of these types of services so might be difficult.

hey @feiszli you could override the sign up API on the backend and disallow such emails

Thanks! Can this be done during validation of the email, so that when they put it into the box, it will tell them it is not allowed?

Yea. Checkout the form field validator page in our docs.

Thank you!
