TowerData is one of the reputed email verification services that is highly accurate. The value-add services like email activity metrics make TowerData a preferred choice amongst other. As a user, the only thing that I found is the minimum order value is $50 which does not sound suitable for verifying email list with fewer records. I found cheaper alternatives with the same offerings and accuracy here https://bulkemailverification.com/service-provider/towerdata
Not the best and not for this money
