If many of your emails are bouncing, there's no doubt your list needs a scrub. It's not fun to think about your database decaying as you work so hard to grow it. But on average, about 25% of it dies every year.

And did you know that your bounce rate is one of the critical metrics determining your ability to reach the inbox? Your email deliverabilityⓘ takes a hit when your bounce rate is 2% or higher. Mailbox providers can direct your emails to the spam folder or block you altogether.

If you're experiencing this problem and are looking for ways to fix it, you may have come across NeverBounce. It's a popular email list cleaningⓘ service that promises to reduce your bounce rate and help your emails land in the inbox.

But is it the right email validationⓘ tool for you?

Below, we examine all the details—accuracy, features, speed, pricing, and customer support—to give you the full picture.

What 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ⓘ
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 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 $39. The company also offers a comprehensive subscription through ZeroBounce ONE™, which gives you 10,000 credits monthly alongside access to all of the platform's deliverability tools, offering immense value for email senders.

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.

NeverBounce interface and integrations

Intuitive UI

NeverBounce's interface is clean, simple, and easy to use. The UI is intuitive, and you quickly understand what the email validation tool can do for you.

If you want to save time and automate your list cleaning, NeverBounce gives you what you need. You can readily integrate NeverBounce on your website with the JavaScript Widget, a webhook, or Zapier. Also you can customize an integration to best fit your needs, depending on the platform.

NeverBounce customer support

Validating your email list shouldn't be a hassle. With a modern platform, you'll be able to upload your list or install the API yourself.

But if you hit any snags while navigating through these email validationⓘ tools, you want to be able to reach a reliable support team – and not an "away" message.

No support available

That's what happened when we tested the NeverBounce chatbox. At first, the bot let us know it was trying to connect us with someone on the NeverBounce team. But within seconds, we learned that none of the customer support representatives were available.

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.

NeverBounce community feedback

Customers say: 3.4 out of 5 stars

When trying to pick an email validation tool like NeverBounce, you may want to know what other users have to say about it.

But there aren't enough reviews of NeverBounce to get a good sense of what features users like and dislike. For whatever reason, customers have not felt compelled to review the service.

On Trustpilot, for instance, NeverBounce has only four reviews, with users giving the service an average of 3.4 stars out of five stars.

NeverBounce alternatives and competitors

There are so many email validationⓘ tools on the market that it can be difficult to differentiate them all. The most popular services include ZeroBounce and Kickbox.

How does NeverBounce stack up?

NeverBounce is comparable to the majority of email verification tools on the market. It might be enough if you're just looking to clean a database. However, improving email deliverability entails so much more than using a clean email list.

For instance, Google and Yahoo's new email sending rules enforce email authentication. If you go with a service like NeverBounce, you will need to find a different service to authenticate your emails with SPF, DKIM, and DMARC. Such tools are now a must for email marketers who want to get results.

As opposed to NeverBounce, an email verification platform like ZeroBounce provides additional tools like inbox placement testing, blacklist monitoring, and email finding. You may find yourself searching for these tools and will definitely need to address email authentication if you haven't already.

If you're looking for minimal, NeverBounce may work for you, but you'll need to supplement with other email deliverability services.

It's hard to find a service like ZeroBounce that offers email verification, email scoringⓘ, email authenticationⓘ, blacklist monitoring, email deliverabilityⓘ tools, and an email finderⓘ – all under one umbrella.

ZeroBounce features

Aside from email list validation, ZeroBounce helps you take care of other email deliverabilityⓘ aspects such as inbox testing, email server configuration, blacklist monitoring, and email authenticationⓘ.

Here's a quick overview of ZeroBounce's features and how they work to make your email marketing campaigns better.

Bulk and real-time email validationⓘ tools

With more than 500,000 users worldwide, ZeroBounce's email validationⓘ tool is one of the most popular. ZeroBounce provides 99.6% email verification accuracy and also offers a money-back guarantee.

ZeroBounce also offers a real-time email validation API. Once connected to your forms, the API starts checking incoming emails almost instantly, rejecting bad data before it slips in.

If your email list grows fast, our bulk email validation API saves you time and energy—all you need to do is program it, and it will run daily checks to detect any subpar contacts.

ZeroBounce provides additional tools to help you improve your email performance and ROI. From email deliverabilityⓘ testing to blacklist monitoring and email finding, ZeroBounce is a multi-tool ally for your email marketing team.

Check Yahoo-related addresses with Verify+ from ZeroBounceⓘ

Email deliverabilityⓘ tools

ZeroBounce's blacklist monitoring tool alerts you if your IP or domain have been blocked so you can take action.

Email authenticationⓘ tools

As of 2024, Google and Yahoo enforced email authentication for all companies and individuals sending more than 5,000 daily emails. ZeroBounce's SPF, DKIM, and DMARC generators help you authenticate your domains, while the DMARC monitoring feature provides real-time spoofing and hacking alerts.

Email finding

ZeroBounce's award-winning email validation tool helps you get your emails to the inbox. But what if you need to find a certain email address first?

The 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.
