Gravity Forms Blacklist has plugin settings page to let you do global settings.
Navigate to your WordPress --> Dashboard --> Forms( Gravity Forms ) --> Blacklist, you'll see setting page link as the following.
Currently there are two settings:
Enable save blocked form data
Let you choose to save blocked form data or not. Here is global settings, you may set this for individual form on form settings page.
Gravity Forms doesn't save form data when field validation failed and our plugin helps you block spam data submitting, so spam form data won't be saved in default. This feature may help you view all spam form data in some case you'd like to do business analysis.
Enable notify administrators
Notify administrator or specific emails when spam data blocked. Here is global settings, you may set this for individual form on form settings page.
With this enabled you may change recipient and edit the email subject, email body.
