While my business focuses on transactional emails, I decided to evaluate this tool and was blown away by the immediate results. The speed and reliability of both the email verifications and the API are outstanding.

My initial positive experience was so compelling that I upgraded my subscription from Tier 3 to Tier 4, and I will likely purchase another license to accommodate future growth. For anyone questioning the value for smaller-scale needs, I can confirm it works exceptionally well. This is a robust and efficient solution that delivers on its promises. Highly recommended
