Require work email validation
Updated December 11, 2025
Use the Require work email toggle to prevent submissions that use free or disposable email domains. When enabled on an email field, the submission fails server-side if the address matches a known freemail pattern (for example gmail.com, outlook.*, yahoo.*, icloud.com, protonmail.*, zoho.*, tuta.*, gmx.*, mailinator.com and other temporary mailbox domains).
Visitors will see the error: “should be a work email, not an email from a free email provider.”
