Cons

Expensive
Among 30+ email verification tools audited by LCA, TowerData is one of the most expensive. The cost of 10K email verification is $100, about six times more than other email verification tools, such as RemoveBounce and DeBounce, which cost just $15 for 10K. According to TowerData's latest audit report, it ranks 28th in the race for most affordable email verifiers.
Less Accurate
As per industry standards, TowerData's accuracy falls behind. In our audit, we achieved only 74% accuracy, which is below the industry standard of 96%. Additionally, it failed to detect catch-all email addresses. In our audit of other email verifiers, TowerData ranks 17th for accuracy.
