Device notification every minute on arduino

Arduino Uno with wifi shield.
I am using the web and Anroid dashboard.
I get every minute a device notification from the scheduler. Since this happend I deleted everything from the scheduler, all projekts and devices from the account and powered the arduino off. But the problem is not solved. The emails lock like this:
