Pros

Quick Verification Process
TowerData is also one of the fastest tools for email verification as it verifies 10K email addresses in 400 minutes, much faster than the industry standard turnaround times of 498 minutes. In terms of verification speed, it cannot compete with the other ten vendors, such as MyEmailVerifier and QuickEmailVerification.

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.

ZeroBounce - Overview

One of the fastest-growing companies in the email verification industry (according to INC. 5000) is ZeroBounce, a US-based email verification service.

With their API integration, you can prevent unwanted sign-ups and have clean email lists. A well-managed API dashboard allows you to look over daily and monthly reports.

They use AI technology to score your catch-all email address, which is risky to send through A.I., providing you with a better idea of whether to send an email to each email address.

While other providers like MyEmailVerifier and Debounce verify 10k emails in less than $30, ZeroBounce charges $60.

You don't have to worry about your data privacy with Zero Bounce. They are Swiss EU-US privacy shield certified vendors. There are only 2-3 vendors with this certification.

Zero Bounce is a qualitative choice if you are looking for extra information about the email validation results and informative analysis.

Facility for scoring
With ZeroBounce, you can grade email addresses from 0 to 10 based on your subscribers' interaction with your emails. 10 is the highest quality rating, and 0 is the lowest. With this score, you can quickly determine which contacts to target and whether they will convert into your final customers.
Commendable customer service

Turnaround time is quick
It took ZeroBounce 43 minutes to verify 10K emails, whereas the average industry standard T/A time for 10K emails is 582 minutes. Therefore, ZeroBounce's actual T/A time is less.
