"Clean and simplified look, array of functionality, and amazing support. Single record verify tab is very useful for quick checks and smaller tasks. Bulk upload is fast and reliable, works much better than other tools I was using."

"It's a very good email verification tool, and in my experience it's superior to its competitors. The main reason is that it has implemented AI correctly, especially for handling catch-all and unknown results. It also provides a confidence score, and during my use of the API I found that score to be accurate."
