Is there a way to have messages that are submitted from a certain person can be deleted or block automatically?

Is there a way to have messages that are submitted from a certain person just be thrown away before they make it to the inbox?

That way she could just submit as much as she wants but i would not see any of it in my inbox. 

If you are referring to delete the submission automatically based on a condition, unfortunately, it is not possible. However, you may set a condition to redirect the email notification to a different email address by using "Change Email Recipient" in the conditions.

Please refer to the guide below that can help you in setting the condition.
