Maybe you need faster turnaround times, cleaner API integration, or a tool that won’t get expensive as your list grows. The good news? There are reliable Zerobounce alternatives out there built for marketers who want more control and better value.

Here are seven strong options worth trying in 2025, whether you’re cleaning a list of 1,000 or scaling for millions.

Zerobounce at a glance

Hailing from Santa Barbara, California, Zerobounce is a popular email verification tool used by over 400,000 big and small businesses globally. Boasting a 99% accuracy, Zerobounce lets anyone validate up to 100 emails for free, so you can get a taste of how the tool works.

Besides email validation, Zerobounce offers email activity data, an email scoring, email finder, and email deliverability functions, like blacklist monitoring. Prices for Zerobounce start from $18 for 2,000 emails i pay-as-you-go rates. Subscription plans are available too.

Zerobounce integrates with all the major email marketing tools on the market, as well as many other CRMs, project management tools (including AI project management software), and other apps.

The tool has a 4.7 score on G2. However, not everything is sunshine and rainbows with this tool.

Why look for Zerobounce alternatives to validate emails?

You may be thinking that with 500+ people reviewing this email validation tool, the data can’t be wrong. Zerobounce has some major faults, though, that could lead you to look for an alternative tool that helps you hit the inbox every time.

First of all, the pricing scheme. Whether you like it or not, you’re forced to buy at least 2,000 credits, which means you have to estimate how many emails you’re going to validate. You may not have an idea how many you need per month so you need to guesstimate. The credits do not expire, but it makes no sense to lock up hundreds of dollars in a tool, only to use it much later.

Moreover, if you take a look at their pricing, it is not what you would call competitive. Compared to most other tools we’ll talk about today, Zerobounce is rather expensive. No matter how many emails you need to validate, the price per email is always higher than most other competitors.

Then there is the issue of speed. If you have large volumes of email addresses, you will first be happy to hear that Zerobounce validates up to 100,000 emails in 45 minutes. In reality, many customers complain about the validation taking significantly longer than that with the typical email list.

Last but not least, is the user experience. Zerobounce offers a wide range of tools in its arsenal (such as email scoring), but using them effectively by small teams or non-technical users can be challenging.

Email verification is a big deal as you want to send emails to existing emails only, as well as avoid spam traps and ultimately maintain an amazing sender reputation.

And perhaps there are better choices than Zerobounce.

The best Zerobounce alternatives for email validation

If you’re not happy with Zeroubounce’s accuracy, pricing, user experience or something entirely different, look no further. These are the best alternatives that fix all the Zerobounce issues and add some benefits on top.

Bouncer

We’re going to be incredibly subjective here and say that Bouncer is the best Zerobounce alternative on the market right now. And we have a proof for that – it’s not all smoke and mirrors.

For one, Bouncer is more precise. It has very high precision with bias against false negatives. This not only ensures you’re sending to the right email address. You won’t also lose the ability to reach out to someone because of the wrong address categorization.

Moreover, Bouncer has the best coverage in the game.

We work with all major email service providers and we can verify the widest variety of email addresses. We even provide a deep catch-all domains verification for Google Workspace and Office 365. This means that even if your list is filled with Gmail addresses, we can verify them. It also translates to a super low amount of unknown results of 0.3%-3%.

If you’re short on time, worry not because we’re lightning fast. Bouncer can verify up to 180,000 email addresses in one hour, making it ideal for bulk email analysis. Even with enormous email lists, all your addresses are verified quickly.

And when you need it, Bouncer will be there. We have a zero-downtime policy, so your campaigns will keep running smoothly at all times. Moreover, we are SOC2 compliant, which means your data is always safe and sound. No one has access to your email lists except yourself.

Last but not least, anyone can use Bouncer because the user experience is super simple.

If you can send an email, you have all the tech knowledge necessary to validate emails and use Bouncer.

When it comes to pricing, it really depends on how many emails you need to verify. You can purchase credits that never expire for as low as $0.0020 per single email. Or if you want consistency in pricing, monthly plans start at $8/month for 1,000 emails.

With Bouncer, you know your email lists are always in great shape and your open rates are on their way to skyrocketing.

Neverbounce

If you’re looking for a wide variety of email verification tools, Neverbounce might be a good email verifier option for you. Besides the traditional dashboard setup, Neverbounce also allows you a few different methods to validate your email list, which is the strongest selling point of this tool.

You can use their custom API, JavaScript code, or a Zapier integration to verify emails at the point of entry. This means that whenever someone submits an email to your lead capture form, Neverbounce first checks it before adding it to any mailing list.

This can be a huge timesaver if you deal with a lot of spammers who clog up your email list and waste your email marketing tool credits. But if you already have an email list, you want to use the dashboard which is fairly easy to use.

Unfortunately, according to G2, Neverbounce is not the most accurate tool out there.

It seems to destroy entire campaigns and some users report really high bounce rates after using this tool… which translates to many emails not reaching the inbox.

Pricing can also be acknowledged as high. And add to this a terrible support.

All in all, a worthy contender, especially if you’re looking to capture emails directly at the point of entry. Just be careful.

Debounce

If you’re looking for a budget-friendly solution with a good variety of features, Debounce deserves a look.

Besides email verification, Debounce can help populate your missing data fields through data enrichment. Moreover, you can use their lead finder, email list monitoring, API, validation widget, or catch-all validator. This all is in Debounce.

If you’re looking for one tool to clean up, manage, enrich, and validate email lists, this might be a good shot.

However, there are many solutions that are better on their own, such as enrichment and web scraping tools, so this remains a nice extra for most users.

Plus, this email verifier does not state how long it takes to validate emails, especially large lists.

As mentioned, pricing is pretty affordable and starts as little as $0.0003 per validated email. There are no fixed monthly packages and you have to purchase validation plans on an as-you-go basis. The smallest package you can go for is 5,000 verifications for $10, which comes in at $0.002 per single email.

One curiosity about Debounce is that besides cash, they accept a variety of cryptocurrencies, including Bitcoin.

Overall, it’s an interesting tool to avoid going to the spam folder, but the lack of flexible pricing can be a dealbreaker for many companies.

Snovio

If email validation is just the tip of the iceberg for your email marketing needs, Snov.io comes to the rescue.

Email verification is just a part of the offer. On top of that, Snovio adds email warmup, email finder, a sales email CRM, and multichannel outreach In short, you can find new email addresses, verify them, warm up a new address, and even start sending out cold emails.

Now, having said all of that, you’re paying for a lot more than verification too, which is the main issue with this tool. The Starter Snovio plan is $30 per month, which gets you 1,000 credits. In the Free plan you have 50 credits.

For email verification alone, this is rather expensive, especially if you don’t need the remaining features that Snovio offers. It’s a capable tool but for someone who just wants to verify emails, Bouncer is a better choice for less money.

Kickbox

You may think that the next tool on the list will be a salesperson’s dream come true as well, but Kickbox is different than Snovio. This app comes with everything you need to send good email campaigns – verification, API, spam checker, disposable meail checker, deliverability consulting, and more. Some of these tools are free.

The email verification part of the app is intuitive and easy to use.

Boasting an alleged 98%% accuracy, Kickbox can capture all types of errors, including syntax errors and typos. They also do a good job at identifying role addresses such as marketing@example.com.

In Kickbox, you pay-as-you-go. You can start for free with 100 verifications. If you want to upgrade, you will pay $5 for 500 verifications. The biggest price is $4,000 for as many as 1,000,000 verifications. If you need more, talk to their sales.

Prices get lower as you add more volume. If you want a good quote on how much it will cost you, you need to ask their team.

It’s a solid tool with a nice range of extras you can opt for if you want a more versatile email marketing assistant.

Briteverify

Build by Validity, Briteverify is one of the oldest tools in the game. Out of all the tools on this list, Briteverify is the vaguest in terms of its advantages when combined with the rest of the Validity offer.

One thing that you have to keep in mind is that Briteverify is very positive when it comes to its validation time. You’ll find them claiming that for 100,000 emails, it takes ~25 minutes to complete a validation, which is optimistic, to say the least.

Briteverify does not allow monthly plans as well.

Instead, you have to purchase credits. What is different is that the minimum amount you can pay is $40 for 5,000 verifications. If you compare prices for more verifications, you’ll see that Briteverify is really expensive compared to the other tools mentioned here.

In short – it’s an expensive tool.

Emailable

If ease of use is your main concern, Emailable is a good call. Just upload a CSV or Google Sheets file or connect your email marketing tool of choice and you’re ready to start your verification process and say goodbye to bad email addresses.

You can verify your lists or emails one by one. The pricing is not exactly competitive. Yet, you have as much as 250 free credits!

As you’ll see that Emailable is a bit more expensive than the other entries on this list. You can get a monthly plan for Deliverability, instead of getting stuck buying credits and thinking about whether you will use them or not. However, for Credits, there are pay-as-you-go rates. At $38, you get 5,000 credits, which allows you to validate 5,000 emails.

Now is getting interesting: on G2 we have found that Emailable tells clients, that it can verify emails – attention – 8x faster than competition! To be specific, it can verify 30,00 per minute = 1,800,000 per hour. We are really curious if it’s true.
