Hi Robin,

I am truly sorry you had a bad experience with us. There was clearly a misunderstanding on how the email alerts work and how they are defined into your account.

Not every change triggers an email notification, and a certain level (you can control) needs to be reached. To receive an email, the change should be greater than:
1. The monitor threshold
2. Your user account global settings

As a side note, your use case implies another limitation to the testing: the price in the pages you were monitoring (AppSumo Product pages) are not subject to a lot of changes, so unfrequent alerts are to be expected.

I appreciate your feedback and understand there's room for improvement on how we manage or explain the email alerting! This will be subject to a review on our side.

Thank you,

Wilfried
