Overview

NeverBounce - Overview

NeverBounce is a well-known bulk email list cleaning service provider. They can verify all types of emails with standard email verification accuracy of 93%. Their pricing for 10K is $50, which is quite reasonable compared to QEV and ZeroBounce, who offer $60 and $65 respectively for 10K.

NeverBounce’s new Sync functionality is unique. This function automatically cleans your email list at Mailchimp and other similar services. They are GDPR compliant and follow the rigorous data security standards of the EU privacy policy. NeverBounce offers a money-back guarantee if you are unsatisfied with the results.

They are the third largest to provide the highest number of integrations up to 80+ with email marketing services and CRMs. NeverBounce received high praise from iContact, Pathom, and even worked with leading companies like Uber, Indeed, Dell, and many more.

Overall, NeverBounce is an excellent choice for businesses who want to focus on verification accuracy but do not want to break the bank.

Pros

Low Turnaround Time
NeverBounce takes only 200 minutes to verify 10K email addresses. It is less than the average industry standard, which is 498 minutes. Because it generates resultant data quickly, we must say that NeverBounce is one of the fastest email verification tools among 35+ other vendors we audited.
Good Integration Facility
NeverBounce also wins for its outstanding integration facility with 80+ applications, including well-known ESPs and other marketing apps.
Excellent Customer Support
Though NeverBounce offers support from 9 am-6 pm EST only, its email and live chat support are excellent and quick. Its support team replies interactively and in detail to any technical query you ask them. However, it takes some time to respond to your question in email; they don’t let you wait for a long time when you ask them in live chat.
API Integration
You can also integrate API developed by NeverBounce in any part of your platform, i.e. website, landing page, or mobile application from where you collect email addresses.

Cons

Not Affordable
With the 16th rank for its affordability, NeverBounce couldn’t make its place in LCA’s recommended cost-effective email verifiers. We found NeverBounce very costly; it charges $50 to verify 10K emails. We at LCA don’t consider this tool cost-effective for startups and small businesses.
Less Accurate
NeverBounce doesn’t provide good accuracy as compared to its high price. Our latest audit report for NeverBounce says that it is 93% accurate, but actually, it should be 96% minimum to be a part of LCA’s most accurate email verifiers list. It ranks 12th for its accuracy found when LCA performed its audit.

TowerData - Overview

TowerData is designed to help email marketers engage customers behind the email address. Apart, from accurate email validation, TowerData also offers services like Email intelligence and Email append. TowerData will be the preferred choice if you are looking from an Intelligent email verification service.

Pros

Quick Verification Process
TowerData is also one of the fastest tools for email verification as it verifies 10K email addresses in 400 minutes, which is less than the average industry standard turnaround time, i.e. 498 minutes. However, it ranks 11th for its verification speed and can't keep pace with the other ten vendors, such as MyEmailVerifier, QuickEmailVerification, etc.
Free Trials & Credits
Like other vendors, TowerData also allows its users to test its interface and verification capability by providing the first 100 credits for free.
Good Integration Facility
TowerData automates your workflows by letting you integrate with 16 other applications, including MailChimp, ConstantContact, Campaign Monitor, etc. It enables you to bring your data automatically from these platforms and manage your marketing activities under a single roof.
Excellent Customer Support
TowerData opens all doors to get in touch with its support team by providing email and phone support. It also offers live chat support during business hours, i.e. Monday through Friday, 9 a.m. to 5 p.m. EST. Moreover, it also lets you set the meeting with its representative, choosing the date and time from its calendar. Thus, we can say that its customer support is outstanding.

Cons

Expensive
TowerData is found as one of the expensive email verification tools among 35+ others audited by LCA. It will cost you $100 for 10K email verification. It is around six times costlier than other email verification tools such as RemoveBounce and DeBounce, whose price is just $15 for 10K email verification. As per the latest audit report of TowerData, it ranks in the 28th position in the race of most affordable email verifiers.
Less Accurate
We at LCA found that TowerData falls behind on its accuracy. We achieved only 93% accuracy during its audit, which must be at least 96% as per the average industry standards. Moreover, it also fails to detect catch-all email addresses. Thus, TowerData ranks 13 for its accuracy among the other email verifiers audited by us.
