Look, I don't know if this is quite 5 stars in my opinion. But it's at least 4.

The fact is: the tool does what it's advertised to do, and it's super easy - so it wouldn't be fair to dock it a point. All that said, something can be TOO simple. Hoping it delivers on multi-page soon, among other things.

Another thought: consider finding a way to let users plug in their own email verification API. Charge a one-time fee, similar to the branding removal, to enable to capability.

All in all, great work on this tool and I wish you the best!
