The Report Phish notification will contain the message initially agreed upon by you and the MetaCompliance Support Team. (Depending on the type of plugin you have chosen, you will have completed a Notification template which was sent to you by MetaCompliance Support.)
Currently, you are unable to edit this Notification independently via the platform.
However, if you wish to edit the message presented to your end user, then please contact us at support@metacompliance.com, and we will resend the 'Notification template' to you so that you can update with your required changes.
