How can we help you?

Bots and spammers frequently pollute lead forms and email lists with temporary, 10-minute disposable email addresses (such as Mailinator, TempMail, and GuerillaMail). With the Gravity Forms Email Validator Premium Add-on, you can filter out invalid and burner email addresses in real time with instant syntax, MX record, and disposable domain checks.

Why Choose Native Email Validation

• Instant Native Validation: Verifies format and domain DNS MX records natively in PHP without third-party API lag.
• Block Disposable Emails: Built-in database blocks over 100+ temporary email generators automatically.
• Zero Metered Fees: Protect unlimited forms without paying recurring per-lookup credit fees.
