I recently tested Voila Norbert, and overall, it works well, although there are improvements to be made regarding its detection rate. For instance, I used the name "Voila Norbert" with the domain example.com. The email v.norbert exists under the specified domain, but the tool was unable to detect it.

On the other hand, it performs well for certain domains. I'm not entirely sure how the logic behind it works, but I believe it's essential to give a product a chance to evolve and mature over time. I look forward to seeing how Voila Norbert develops in the future.

All the best
