blox is our new favorite employee. it caught a blocked person (return fraud) who kept making new emails and still caught every one of them. Absolutely legendary and so satisfying to watch

Looooove blox. We have a huge issue dealing with a ton of return fraud/abuse as well as weird customer behavior. Been using Blox to find unprofitable or problematic customers and cut them out of our customer file to save us the operational and financial headache
