Require work email validation
Updated December 11, 2025
Also available in:
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.”
