Description
Enables users to change the email validation for the TO address on notification pages. Useful to allow merge tags or shortcodes to be added to the TO field.
Usage
add_filter( 'gform_is_valid_notification_to', 'validate_to_email', 10, 4 );
Parameters
- $is_valid boolean
The value being filtered. True if the to email is valid. False otherwise. Gravity Forms performs the validation before executing this hook, so $is_valid will contain the result of that validation. To override Gravity Form’s validation, simply set the value of this variable to true or false and return it.

The email address configured. Only applies when type ($to_type) is set to “email”
-
$to_field string
The ID of the field selected to be used as the “Send To”. Only applies when type ($to_type) is set to “field”
