Efficient Email Organization with Proofy.io

What caught my attention the most was the organization of the results on Proofy.io. I think the tool effectively separates valid emails, invalid ones, and those considered more risky, which greatly facilitates my decision-making before sending. Additionally, the initial setup was easy, and I liked that.
