Design issue with webhook (several) notifications on mixmax.com

How it was found

Hi team,

I noticed a design problem involving successive notifications about an incorrect webhook set at https://app.mixmax.com/dashboard/settings/rules

I set an incorrect webhook (for testing) on this page and in a few hours I received more than 10 notifications.

This can cause a certain inconvenience to users due to the amount of emails sent by [email protected]
