Can I block disposable email addresses (Mailinator, 10MinuteMail, etc.) in FormNX?

Yes. FormNX has a built-in disposable email checker on the Email field. Tick the 'Block Disposable Emails' checkbox in the field configuration and FormNX automatically rejects emails from known throwaway providers - Mailinator, 10MinuteMail, Guerrilla Mail, Temp-Mail, YOPmail, and thousands of similar services. Respondents who try to submit a disposable email get the message: 'Please use a real email address. Disposable emails are not allowed.' The disposable email domain list is maintained by FormNX, so new throwaway providers are added as they appear - you never have to update it. Block Disposable Emails is available on FormNX Pro plans, and pairs naturally with Email Verification (OTP) for the strongest contact-quality protection.
