Try ZeroBounce freeWhat is NeverBounce?
NeverBounce is an email validation tool helping 125,000 companies check their email lists to improve email deliverability and campaign performance. NeverBounce offers bulk and real-time email verification and integrates with more than 80 platforms.
In 2019, NeverBounce changed ownership but continuously operated under the name “NeverBounce.”
An overview of NeverBounce
NeverBounce was founded by Brad Owen in 2013, in Beachwood, Ohio. The email verification software was designed for “companies that send large email blasts” to “weed out bad email addresses.”
NeverBounce was acquired by DiscoverOrg (now ZoomInfo) in 2019 and is currently based in Vancouver, Washington.
NeverBounce offers three tools:
- Clean: bulk email list cleaning
- Verify: real-time email verification
- Sync: automated list cleaning.
NeverBounce features
Next, let’s take a closer look at NeverBounce’s features and understand how the email validation tool helps you keep a healthy list.
NeverBounce provides two ways for you to maintain good email hygiene:
- bulk email validationⓘA form of email validation that allows users to upload a list of email addresses as a file either via direct upload, the cloud, or a platform integration. The email validation process is completed after all email addresses on the list are validated.
- real-time email verification.
NeverBounce Clean: Bulk email validation
If you have an email list that’s giving you trouble, bulk email validation is the way to go. This feature – which NeverBounce calls “Clean” – allows you to check emails in bulk by uploading your list onto the platform.
NeverBounce may not detect abuse emails
NeverBounce identifies invalid email addresses, spam traps, catch-all emailsⓘAn email set up by a business to capture email messages sent to their name via an invalid address (e.g., j0hn@company.com instead of john@company.com). Catch-all inboxes receive a high volume of spam and may not be actively monitored by the owner., and disposable emails. However, the company doesn’t disclose whether its software can detect toxic domains and abuse emails (known complainers likely to report your emails as spam).

NeverBounce Verify: Real-time email verification
It’s important that a list verification service also provides real-time email validation. Any form is a potential way for bad data to leak into your email database. So, once you’ve cleaned your list in bulk and got rid of existing poor-quality data, you want to make sure it doesn’t reinfect your list.
How the API works
NeverBounce makes it easy to check emails in real time by providing an email validation API – a product NeverBounce markets as “Verify.” You can hook the Verify API to all your registration and sign-up forms to prevent fake and invalid contacts from getting on your list.

NeverBounce Sync: automated list cleaning
Let’s say you just cleaned your email list in bulk and want to make sure no invalid emails find their way into your database again.
Clean your data daily
NeverBounce Sync allows you to automate the real-time email verification process and save time. You can connect Sync to your email service provider and rest assured that your data is cleaned daily.
NeverBounce accuracy and reliability
Accuracy is paramount when selecting an email list verification service.
Your email database should be free of problematic or defunct email addresses. At the same time, you don’t want an email checker to misidentify a valid email address as one you should part with.
99.9% accuracy
On its website, NeverBounce claims its email validation tool is 99.9% accurate. The company also promises a 97% deliverability rate. You can get your money back if more than 3% of your emails bounce after your list cleaning.
NeverBounce speed and performance
Speed varies for large volumes
By most accounts, NeverBounce is a service with a decent speed. However, according to its website, the NeverBounce email validation tool's speed varies greatly when processing large volumes of emails. Ten thousand emails take three to ten minutes to complete, meaning 100,000 emails could take quite a while.
Data protection and security at NeverBounce
As data processors, email validation services must adhere to strict data security and protection protocols. NeverBounce’s communication on this topic is minimal.
The company's website mentions that it prioritizes data protection and security by maintaining its operational and data processing systems in a secure environment. It uses administrative, technical, and physical safeguards to protect customer personal data from unauthorized access.
GDPR compliant
NeverBounce is GDPR compliant and reviews its internal protocols and third-party relationships to establish comprehensive policies governing data security, encryption, and data transfers. Furthermore, NeverBounce adheres to both the EU-U.S. Privacy Shield and the Swiss-U.S. Privacy Shield Frameworks.
NeverBounce pricing and value
Both ZeroBounce and NeverBounce allow you to try the service for free – but there are some differences.
Only 10 free credits
NeverBounce allows you to check 10 email addresses to try it out. On the other hand, ZeroBounce provides 100 free email credits each and every month. Someone with a beginning list can use the service every month until the list expands beyond 100 subscribers. For small lists under 100, ZeroBounce’s pricing is superior. There is no cost.
Another critical difference is that NeverBounce credits expire after one year, while ZeroBounce credits never expire.
When it comes to the paid service, NeverBounce’s pricing is upfront and easy to understand. The company classifies its cost structures into three tiers. On the low volume end, it sells 1,000 credits for $8, while 2 million credits will cost $4,000.
ZeroBounce also offers accessible and easy-to-understand pricing. ZeroBounce requires a purchase of at least 2,000 credits, which is $18. The company gives you a pay-as-you-go option, in case you need to clean your list just one time. But also, you can get a subscription and save money every month on email validation.
At certain credit plans, ZeroBounce and NeverBounce cost the same, but one is sometimes more cost-effective than the other. For instance, at higher credit volumes, like 100,000 or 1 million+, ZeroBounce will save you money.

We tried the chatbox on another day, during business hours, and got the same response.
Next, we called NeverBounce’s toll-free number, but our calls went unanswered, with the option to leave a voicemail.

Check 100 emails for freeThe benefits of using an email validation tool
Email marketing is as powerful as ever, with 40% of consumers saying they check their inboxes looking for brand discounts. But that’s the thing: you need to be in the inbox to make a sale. And using a clean, valid email list to avoid bounces is one of the ways you get there.
A good email validation tool gives you benefits like:
- A better sender reputation, which is a score mailbox providers use to determine whether you’re a legitimate sender
- Higher email deliverability and a chance to connect with real prospects
- An increase in metrics such as click rates and conversions.
Email validation will also decrease costs. As email service providers charge based on the number of subscribers and the number of emails sent, keeping invalid and inactive contacts is a waste.
Email validation can rehabilitate a decaying list and prevent a good email list from unraveling.
In one instance, our customer MediaShares, a company that consults with companies to market investment shares, was able to salvage its list. What started as out-of-control email bounces ended in a 0% bounce rate after MediaShares used ZeroBounce. Fixing and preserving your list means you can enjoy better email marketing results.
