The Newfangled Email Blacklist is a plugin that requires business email domains to be used when Gravity Forms are submitted. If a blacklisted email domain (e.g., Gmail) is detected, the user will be prompted to enter a different email domain. Optionally, they can confirm the use of their blacklisted email address by checking a confirmation checkbox.

The Newfangled Gravity Forms Helper plugin includes a setting that prevents forms from being submitted with the same value in the First Name and Last Name field. Many spam submissions will use the same value for both fields.
