To combat this problem, email marketers can use a number of email list validation services. Two of the most popular choices for bulk email list cleaning are NeverBounce and Zerobounce.
And while both seem like a good choice to the untrained eye, there are some differences you should bear in mind when deciding. Here is how the two tools compare in major email verification categories.
NeverBounce vs Zerobounce at a glance
NeverBounce is a company owned by the renowned software mogul ZoomInfo and it has a customer base of over 125,000 businesses that use it for email validation.

Much like Zerobounce’s email checker, it focuses on an enterprise audience, but it’s also used by large and small businesses globally that check addresses and email domains for accuracy. Its accuracy should be 99.9%, as stated on their website.
Ease of use is the name of the game with NeverBounce, with three major options for email verification: bulk cleaning, real-time verification, and automated list cleaning.
On the other hand, Zerobounce touts itself as the enterprise solution for email verification, with over 400,000 customers around the world. In the industry, it is known for its higher-than-average pricing and decent accuracy rate of 99%.
Zerobounce is also a pretty versatile tool that offers more than just validation services for lists and single emails. On top of that, there are inbox placement tools, blacklist monitoring tools, a disposable email checker and an email finder in case you’re having trouble building up a list.
NeverBounce vs Zerobounce – email verification and additional features
NeverBounce gives some extra options.
First up is the bulk list email cleaning, which allows you to verify emails either from the NeverBounce dashboard or through their API.
You can get simple results broken down into categories such as valid, invalid, catch-all, or spam. As we’ll explain in a minute, the cleaning is pretty fast (but sometimes it’s problematic).
There is also real-time verification, which you can add to your website to verify emails at the point of entry and help you avoid the spam folder when reaching out to your contact list. As someone leaves their email, you can immediately discard them if they entered a typo or an invalid email address.
Then there is the automated list cleaning. This is one of the key features where you can connect your CRM or email service providers and NeverBounce goes through the list daily to remove invalid addresses. While it is a good addition to the tool stack, it can get very pricey with larger lists.
On the other hand, Zerobounce has a more comprehensive list of services in their email bounce validator.
Besides email list validation, you also get email activity data in this email checker, which essentially shows you which subscribers are the most engaged with your content. This is a helpful tool if you want to boost email rates (like opens, clicks) or remove inactive addresses from your list.
There is also an Email Scoring feature that grades your list and gives you a score for how active and valuable it is. While it is a nice feature, it’s not as necessary for businesses just looking for email validation.
Then there are email testing tools that help you find out how many of your emails land in customers’ inboxes. This coupled with the blacklist monitor can be extremely useful if you’re worried about your sender reputation and improving email deliverability.
Plus, there is also an email finder that works just like any other email finder tool – add a domain and a name, and Zerobounce finds the email addresses and other missing data and validates it in real time.
The verdict
On the whole, it seems like Zerobounce has more features, but it’s debatable whether those features are critical to a business looking for email verification services.
NeverBounce has a more compact list of features but they all provide value.
Looking at email verification, disposable email detection, spam trap detection, and accompanying tools alone, it’s a tie between Zerobounce and NeverBounce.
NeverBounce vs Zerobounce – pricing
NeverBounce has two ways to pay for validation – Basic Plans with pay-as-you-go rates and Sync. For this first option, prices start from $8 for 1,000 credits and $16 for 2,000 credits. The minimum purchase is 1,000 credits.
As you validate more emails, the price drops to as low as $0.002 per email – like if you have 2 million emails to validate.
In the separate pricing model, Sync, prices start at $10 for 1,000 emails.
After signing up, you have 10 free credits.
Zerobounce has two pricing models as well: Pay-as-you-go rates (in their case, there is a minimum purchase of 2,000 emails) and subscription models for Email Deliverability Suite:
- Free
- Starter
- Team
- Pro
If you’re going monthly in pay-as-you-go rates, you’ll end up paying a minimum of $18 for 2,000 emails. If it’s one-time, you will pay for 2,000 emails $20.
As you scale up your number of verified emails, the price drops, all the way to $0.00275 per email if you have more than a million email subscribers.
If you purchase credits, they never expire, so you can use them whenever you want to.
After signing up, you have 100 free credits.
The verdict
Both tools are priced similarly, with NeverBounce being slightly cheaper. Yet, we would give a try to Zerobounce because it has a more flexible setup with more free credits and features.
The speed of email verification
If you have large email lists, the speed of verification is a major concern. Here is how the two tools stack up against each other.
NeverBounce offers and promises to validate 10,000 emails in anywhere from 2 to 10 minutes. In other words, it should take them max 100 minutes to complete the job of verifying around 100,000 email addresses.
Zerobounce, on the other hand, tells that it takes about 45 minutes to validate 100,000 email addresses.
The verdict
On this front, Zerobounce may seem better.
NeverBounce vs Zerobounce – user reviews
There is really a mix of opinions regarding NeverBounce. You can find both positive and negative reviews. Some are generally speaking in favor of its speed and ease of use, while many users complain about the high price, poor support, or high bounce rates compared to the competition.
If you take a look at Zeroubounce G2 reviews, you’ll find that most customers are satisfied with the email verification services. Many highlight good accuracy and speed. Still, there are some complaints about the pricing being a bit high.
