10 Best Email Verification Services Compared


Introduction to email verification

Email verification is the process of checking the validity of an email address without sending an email. 

The various email verification services compared in this article carry out multiple validation checks. However, the three primary goals of email validation are:

  • To check whether the email address has the correct syntax,
  • To find out whether the email inbox exists, and
  • To assess the quality of the email address

Whether you have just a few email addresses on your email list or whether you have hundreds of thousands of them, verifying email addresses will hugely improve your email marketing results, save you from penalties and help you in a number of ways.

BriteVerify reviews

BriteVerify is an old player in the email verification industry. Some time back it was taken over by Validity. Apart from BriteVerify, Validity also owns ReturnPath, a service that can help you with sender reputation.

So what makes BriteVerify a great email verifier? 

  • A smooth interface to easily verify your email list. Verify individual emails or entire lists 
  • Real-time email verification API
  • Use three tests: syntax checking, MX record checking and authenticating with the email server of the address. 
  • Each email validation takes about 0.5 seconds, which is pretty fast.

BriteVerify Features

Here are the top features of BriteVerify, the preferred email validator of many businesses:

Upload / download options: 

  • BriteVerify allows CSV and TXT files in uploads and downloads. In case you store your email contacts in, say, XLS format, you can easily convert it into CSV before you begin BriteVerify. 

Schedule a demo: 

  • While a clear free trial isn’t clearly visible on their website, you can request to schedule a free demo. That way you can check the service and understand its features before making a purchase.

Selectable Download Options: 

  • After the email verification process, you may download any of the four types of email lists: Valid emails, Invalid emails, Risky emails and All emails. 
  • If using an ESP, it’s best to download the Valid emails list.


  • Interface and layout of the site not impressive 
  • Resources like blogs aren’t highlighted enough on website

BriteVerify Pricing: 

While the service may look a bit pricey at first, you must realize that, in its own words, BriteVerify is “the industry’s longest standing and most complete verification solution”. Here’s BriteVerify pricing for some of its popular packages: 

  • 5,000 verifications: $40
  • 10,000 verifications: $80
  • 50,000 verifications: $325
  • 100,000 verifications: $600

As an email validation platform, BriteVerify has its distinct advantages. Firstly, it’s a part of Validity that has other software solutions under its fold. If you have a wide range of email problems to solve and are looking for a one-stop solution, BriteVerify is a service you’d want to check out.

In addition to real-time email verification, you can also get phone and address verification. For a marketer who’s looking for a bundle of verification services that can go beyond email, BriteVerify is certainly a tool to consider.

3. Kickbox


Pricing$ 400 for 50,000 credits
Free trialTotal 100 credits
Customer Support AvailableYes

Integrations24 integrations

Kickbox reviews

Kickbox is another platform whose name you’ll see in almost every list of top email verification services. 

  • Kickbox classifies all its results as one of the following: “Deliverable,” “Undeliverable,” “Risky,” or “Unknown”. This makes it easy to understand your list quality.
  • The free trial for new customers is easy to claim – just sign up and you’re pretty much good to go.
  • Kickbox has a separate portal for agencies. With that you can serve each client separately, improve their email data quality, and help them resolve deliverability issues.

Kickbox Features

As one of the top email checker tools, Kickbox offers several great features. Here are some of them:

Sendex score:

Kickbox has developed a feature they call the Sendex Score. 

  • It is a numerical value between 0 and 1 that Kickbox assigns to an email address. Higher the score, better the quality of the address. 
  • Kickbox also suggests a range of scores that it considers Good, Fair or Poor for transactional and marketing emails. 
  • Kickbox uses its email verification results to regularly learn about what constitutes a high-quality email address. For instance, an address like mary.poppins @ domain .com is rated to be higher quality than an address like qwerqwer @ domain . com. 

95% Email deliverability guarantee: 

  • Kickbox offers a clear 95% deliverability guarantee. If more than 5% of the emails sent to addresses classified Deliverable bounce back undelivered, paying customers are eligible for refund on a pro-rata basis. Bounces due to poor sender reputation, purchased lists etc aren’t eligible for a refund.

Team accounts:

Normally, only one person would have been authorised to use the email verification service. However, Kickbox has an option of a team account.

  • Kickbox offers team accounts, so multiple users can access the same account, manage email verification and can carry out bulk email validation simultaneously.

Data Protection: 

  • Kickbox is GDPR (General Data Protection Regulations) compliant.
  • Kickbox claims to be the first email verifier approved under the new EU-US Privacy Shield data transfer program.

Kickbox Pricing 

Most users agree that Kickbox is fairly priced vis-a-vis the service and quality of verification it provides. Here’s Kickbox pricing for a few of their popular packages: 

  • 5,000 verifications: $40
  • 10,000 verifications: $80
  • 50,000 verifications: $400
  • 100,000 verifications: $800

Why choose Kickbox

The Kickbox team has been into email technology for over ten years. That means when you sign up for Kickbox, you sign up for experience combined with expertise, which is a big plus. They have developed a system to provide accurate results even for those email addresses where other service providers may have to limit themselves to “Result: Unknown”.

Considering all this, we feel you should consider adding Kickbox to your list of tools for bulk validation.

4. NeverBounce (A part of DiscoverOrg)


Pricing$ 250 for 50,000 credits
Free trialTotal 1,000 credits
Customer Support AvailableYes
Data SecurityGDPR compliant
Real-time verification APIAvailable


NeverBounce Reviews

NeverBounce were originally a digital marketing company and they had built this bulk email verification platform ‘out of their own necessity’. Naturally, you can expect them to be both inexpensive and easy to use, in addition to being accurate.

  • As compared to some of the other competitors here, NeverBounce offers great prices. For instance, for 50,000 credits NeverBounce charges exactly half of Briteverify.
  • They’ve made using the free trial easy. All you need to do is sign up and that’s it. 
  • They promise you a fast turnaround: approximately 3 minutes for 10,000 email verifications. 

NeverBounce Features

Business of all sizes find the features of NeverBounce highly valuable. Here is a summary of some of those features:

Discounts for nonprofits: 

  • NeverBounce offers a flat 20% discount to all eligible nonprofits. In order to be eligible for a discount, the nonprofit should be a 501(c)(3)-designated charitable nonprofit organization and have internet presence or public reference on the internet.

97% Deliverability guarantee: 

  • Just like Kickbox, NeverBounce also offers a deliverability guarantee. Subject to certain terms, NeverBounce guarantees that no more than 3% of your emails will bounce. 
  • Bounces from free email service providers (Gmail, Yahoo etc) are not eligible for refunds.
  • The minimum list for a refund eligibility is 500 unique addresses.

Discounts for startups: 

  • Startups are eligible for a 30% discount. Certain conditions, like age of the startup (no more than 2 years old), privately held and an internet presence, are applicable.
  • Once your request for a discount is approved, your startup account can enjoy the discount for 2 years.

Team accounts: 

  • NeverBounce allows organizations to opt for team accounts where the admin or account owner can add team members.
  • The account owner or admin can decide which team member gets to use how many email credits and view account usage and lists of other team members.

NeverBounce Pricing 

NeverBounce offers great value for money. You’ll find great bargains as your volume increases. Here’s NeverBounce pricing for a few of its popular packages: 

  • 5,000 verifications: $40
  • 10,000 verifications: $50
  • 50,000 verifications: $250
  • 100,000 verifications: $400

Why choose NeverBounce

Aggressive pricing and a slightly better deliverability guarantee makes NeverBounce one of the best email verification services here. As an email verifier, they have been in the business for six years now (est 2014) and their long standing experience is certainly in their favor.

Of course, they don’t have a unique feature of email quality scoring like some of the other email tester tools here. We believe that companies looking for a value for money email validation platform will definitely want to explore NeverBounce.

5. Snov.io


Pricing$207 for 50,000 verifications (One verification consumes 0.5 credits, so to arrive at a comparable number for pricing, we combined their two offers of 20k and 5k credits)

Snov.io reviews

Snov.io enjoys a unique place in that it has a bouquet of services available which includes email verification, email finding, email tracking, finding web technologies and more.

  • Snov.io supports multiple languages. That includes English, Portuguese, Russian, Ukrainian and Chinese (Simplified). That’s a big plus.
  • As one user mentioned on a review site, Snov.io is a “versatile platform”. While it’s better known for some of its other services, their email checker tool is great too.

Snov.io Features

Snov.io is one of those few brands that offer a wide range of services. Here are some of the best features of Snov.io email verification:

The 7-step process

  • Every email that’s put up for verification passes through a series of 7 steps before the system determines the validity of the email. These steps include format check, domain check, MX record check, SMTP authentication and so on. 

Catch-all identification

  • Snov.io email verification system can identify catch-all email addresses. This is important because catch-all email addresses typically have poor engagement and hence email marketers prefer not sending their campaigns to such addresses. 

Gibberish identification

  • Gibberish email addresses are those emails which are spelled in a meaningless pattern that real users are unlikely to use. For instance, mary77[at]domain(dot)com is alright but ma7p88zes2[at]domain(dot)com is most likely to be gibberish. Snov.io also identifies the pattern and classifies such emails as gibberish. 
  • Because gibberish emails are auto-generated, they most likely don’t belong to a real user. As a result, such emails would be classified as doubtful or poor-quality emails. 

Chrome extension

  • Snov.io has a Chrome extension that you can use to verify email addresses mentioned on the website you are surfing. 
  • After installing the extension, open the website whose email addresses you’d want to validate. The extension will list out all the email addresses mentioned on the website. You can change the settings to decide which ones you’d like to verify.

Snov.io Pricing

The pricing model of Snov.io is based on the number of credits you may buy. Each credit gives you 2 email verifications. As an example, if you buy 1,000 credits, you can verify as many as 2,000 email addresses. Here’s Snov.io pricing for some of its popular packages: 

  • 10,000 verifications: $66
  • 40,000 verifications: $141
  • 100,000 verifications: $241
  • 200,000 verifications: $482

Who choose Snov.io

To begin with, Snov.io has cleaned over 90 million emails in the previous year itself. This is a proof of its credibility, robust system and quality of results.

Next, Snov.io has a great customer support team. So just in case you need help, they have your back. Finally, their pricing is quite reasonable if you look at their features. We would certainly recommend Snov.io to businesses who are looking to improve their email data quality.

MyEmailVerifier reviews

As a newcomer to the email list validation space, MyEmailVerifier brings some good features, in addition to the great pricing options.

  • Many services struggle to get past free email services like Yahoo and Gmail. MyEmailVerifier claims they can spot the “disabled users” in Yahoo and AOL. This is a great feature.
  • Bulk discounts are available for students and non-profits. Besides, you can request for a  special lockdown discount if you think your business was adversely impacted during the pandemic lockdown. 

MyEmailVerifier Features

It’s interesting to note that though they are not very old,  they have most of the features you’d expect in a top email list cleaning service.

Spam trap detection:

MyEmailVerifier can detect spam traps. While it must be understood that no email validator can fully remove all spam traps from your list, this is certainly a very important feature.

  • Since spam trap email addresses are never submitted to sign up forms, anyone emailing to this address is clearly sending unsolicited emails.
  • The presence of spam traps on your mailing list indicates at least some of your email addresses have been purchased or you didn’t use double opt-in. 

Turnaround time and speed:

We feel MyEmailVerifier is a moderate performer when it comes to turnaround time, however, with a good reason.

  • It takes between 10 to 15 minutes to verify 1,000 emails. 
  • However, they have clearly mentioned on their website that they are slow because they do not wish to compromise the quality of results just to be faster.

Team accounts:

Agencies or large organizations have special needs and may need multi-use access to accounts or more than one APIs for the same account.

  • They do not seem to offer team accounts.
  • If you wish to run more than 1 APIs from a single account, you need to send them an email. They will respond to let you know if they can arrange for that.

Scaled free credits:

The basic free plan allows you 100 free credits just by signing up. However, if you are looking for more free credits, there is some good news. 

  • You send them a request for more free credits and they will add 500 credits to your account. You can also win 500 free credits by posting about them on forums.
  • Submit your review on G2, TrustPilot or Capterra and you might get 5,000 free credits. A video testimonial can bring you another 10,000 free credits.

Real-time verification API:

A real-time API lets you check email addresses in real-time.

  • This feature is important for your sign-up forms, inquiry forms or other webforms where users submit their email address to your system.
  • MyEmailVerifier has the API available for languages like PHP, Java, Ruby, Perl, and .Net.

MyEmailVerifier Pricing 

MyEmailVerifier is currently offering big  discounts. Here’s MyEmailVerifier pricing for a few of its popular packages: 

  • 5,000 verifications: $11*
  • 10,000 verifications: $22
  • 50,000 verifications: $69
  • 100,000 verifications: $89

Why Choose MyEmailVerifier

MyEmailVerifier has become an easy-to-use email list cleaning service for many reasons. Their pricing, features, and overall result quality lead us to believe that it’s a service you’d want to check out.

Their interface is simple and clutter-free, making it easy to use. All this makes them a popular bulk email verifier.

MillionVerifier reviews

Even though they are a relatively new entrant, MillionVerifier has quickly become a significant email list cleaning service provider.

  • Very competitively priced; their service costs about one-fourth or less of some of the other services listed here
  • They offer 100% money-back guarantee. 

MillionVerifier Features

MillionVerifier offers many of the features that you’d expect from a good email validation tool. The challenge, of course, is that their site has very little information to 

Value for money:

It is clear that MillionVerifier is positioning itself as a competitively priced, value-for-money hard bounce checker. 

  • If you buy 5 million credits, you can get 1 million credits for free. That’s certainly a great deal if you’ve got big requirements. 
  • It’s primarily looking for companies with huge requirements. 

Turnaround time:

Speed is certainly a strong feature of MillionVerifier. 

  • Their standard speed is verifying about 3,000 emails per minute, about the same as NeverBounce.
  • It takes about an hour to clean about 100,000 emails.

Accuracy and refunds:

Hungary-based MillionVerifier offers a 100% money refund guarantee. This is quite good, considering that even some of the leading email verification service providers too don’t have this. However, the fine-print for the conditions is interesting.

  • The guarantee applies only if you get a hard bounce of 4% or more. Therefore, the net  accuracy rate guarantee is 96%.
  • To qualify for the guarantee, you must have sent the emails through a third-party email sender (read ESP). 
  • Upon refund, your account and the data therein will be deleted.

Cut the chase:

Their site content and offers are directed to get things done quickly. So while you won’t find blogs or detailed videos anywhere, it also suggests that their target group is companies who understand email marketing well.

  • The homepage gives you the Data Processing Agreement (DPA) upfront. That way, you understand exactly how they deal with your data and know everything before you even try their tool for free. 
  • For real-time email verification and API, you can use the samples codes that are available in Bash, Go, PHP and Python.

MillionVerifier Pricing 

MillionVerifier pricing starts with a slightly bigger volume, i.e. at 50,000 email verifications. Here’s MillionVerifier pricing for a few of its popular packages: 

  • 5,000 verifications: N/A
  • 10,000 verifications: $37
  • 50,000 verifications:: $77
  • 100,000 verifications: $129

Why choose MillionVerifier

Founded by Tamas Szabo, an email deliverability expert, MillionVerifier is certainly one of the services we’d recommend for the price value proposition. What’s more, they are partners with Email Academy and ColdCampaigns. The latter will help you with your cold email campaigns and is available free of cost, at least for the year of 2021.

MillionVerifier and Hubuco are run by the same company, Hubuco Ltd. As MillionVerifier themselves confessed, Hubuco is reducing its support – which probably means MillionVerifier is going to see more push and support from the parent company.

8. ZeroBounce


Pricing$ 325 for 50,000 credits
Free trial100 free credits
Customer Support AvailableYes
Data SecurityGDPR compliant
IntegrationsTheir site mentions 9 official integrations
Real-time verification APIAvailable


ZeroBounce reviews

ZeroBounce is certainly an important bulk email verifier you should consider. 

  • Great security for your email data
  • GDPR-compliant and automatically delete your data after 30 days
  • 98% accuracy
  • Data appends of first name and last name by running email address past older databases (The success of this feature is unknown but nevertheless) 
  • Reliable and prompt customer support

ZeroBounce Features

Just like other top email verification companies, ZeroBounce too has a large number of features. We’ll analyze its five features here.

Spam Trap Checker:

ZeroBounce will check if there are any spam trap addresses on your list, mostly by comparing them with the spam trap list they have in their database. That’s an important feature. Understand two important things about spam traps:

  • Firstly, spam traps fiercely guard their existence, so out of the many spam traps, only a few can be known. 
  • Secondly, new spam traps are created almost daily, so there’s no way any system knows all the spam traps. 

Email Gender Append: 

  • This feature seeks to identify the gender of the person behind the email address. If ZeroBounce can ascertain the gender, they will append it to the email address.
  • While interesting, its not important in the overall email verification outcome

Catch-All Email Checker: 

  • ZeroBounce checks and reports if the email address is a catch-all address. 
  • Nearly every email list cleaning service offers this feature. 

A.I. Email Scoring: 

  • ZeroBounce uses AI to attach scores between 1 and 10 for each email address. A score above 5 means the email address is safe to send. 
  • Verification results show if an address is deliverable or not. Hence this feature doesn’t bring any additional insight.

Selectable Download Options: 

  • You decide what emails you’d like to keep. For instance, you might want to download the role-addresses separately and send them a fresh opt-in email.

ZeroBounce Pricing 

ZeroBounce offers simple pricing tiers. Here’s ZeroBounce pricing for a few of its popular packages: 

  • 5,000 verifications: $39
  • 10,000 verifications: $65
  • 50,000 verifications: $325
  • 100,000 verifications: $390

Why choose ZeroBounce

ZeroBounce definitely is a service to check out. Their security and accuracy is quite good. 

Considering their features, pricing and a strong email verification algorithm, it’s certainly a powerful bulk email list cleaner. We do recommend you give it a try..

9. XVerify


Pricing$ 230 for 50,000 credits
Free trial100 free credits
Customer Support AvailableYes
Data SecurityGDPR compliant
Real-time verification APIYes


XVerify reviews

As far as bulk email verification is concerned, XVerify is accurate and pretty fast in cleaning your email list.

  • There are two ways you can check their service without making a payment. Either sign up for an account and their rep will schedule your free trial (volume unknown). Or, verify 5 email addresses for free, using their free email verifier tool. However, the latter doesn’t give you any detailed insights other than whether the address is valid or not.
  • They are ‘mobile-ready’. According to website, their Javascript will protect you from incorrect results arising out of dumb thumbs.

XVerify Features

Send Shield technology: 

The multi-level checks they perform, branded Send Shield technology by XVerify, puts email addresses through different levels of verification.

  • Each level is a check. It starts with the basic syntax checking, followed by a comparison with the XVerify database.
  • They use a feedback loop from industries to figure out if the user behind the email address is a ‘frequent complainer’. 

Real time validation without cache: 

Like most other services, XVerify too makes sure the email verification is carried out in real-time. 

  • The service carries out a fresh check every time an email address is presented for verification.
  • However, it must be borne in mind that tests like spam track checking have to generally rely on cached results, because real-time verification can’t check if an address is a spam trap.

Javascript validation: 

  • Their Javascript validation gives you a ready-made script that you simply paste in your HTML and verify emails in real-time.
  • In addition to the basic syntax check, this check will perform additional checks like format of the email address as approved by the domain Of course, this is possible only when XVerify knows about the criteria a domain has laid down.

Data security: 

  • XVerify is GDPR compliant, which means they follow the European Union’s guidelines of handling personal data. Data Processing Addendums are made available to all clients upon request. 
  • They are certified for EU-US Privacy Shield Framework and also for the Swiss-US Privacy Shield Framework. The two are slightly different.

Fraud protection: 

  • Their fraud protection measure lets them see if the email address is associated with any fraudulent online activities including false chargebacks (typically associated with temporary email accounts). 
  • It must be borne in mind that such checks have clear limitations because fraudsters keep themselves a step ahead of such checks. Hence, treat such checks as basic and not fool-proof.

XVerify Pricing 

With XVerify, there’s no minimum. Here’s XVerify pricing for a few of its popular packages: 

  • 5,000 verifications: $37
  • 10,000 verifications: $65
  • 50,000 verifications: $230
  • 100,000 verifications: $370

Why choose XVerify

XVerify is certainly a major email validation service with a long history. It is strong on all the major factors like accuracy and speed. Their pricing is fairly competitive too and in the current list, they’re certainly among the best-priced email validation providers.

Another good thing about them is they’re honest about spam traps. While some email verifications companies claim they remove spam traps, XVerify explains it’s not possible to check spam traps since they’re a moving target – the list is always expanding. And besides, if you use only opt-ins, you don’t have to worry much about spam traps. 

On the whole, a good service that you might want to check out at least once.

Verifalia reviews

A part of the Cobisi group, Verifalia offers a simple, quick and reliable email verification and validation service that businesses of all sizes can trust. As a part of the list validation process, they check email syntax, carry out SMTP verification and so on, like any other bulk email verifier. 

  • Verifalia can check temporary outages of mailboxes. In other words, they can detect if a mailbox is temporarily unavailable when it is down at the moment, it is full at the moment of checking and so on.
  • Verifalia offers good flexibility: they accept XLS, XLSX, CSV and TSV files for uploads. 

Verifalia Features

As one of the leading service providers for email scrubbing, Verifalia has many great features, some of which are discussed below:

Multiple email validation passes: 

This is a slightly different idea. 

  • Every pass is a validation test that determines whether an email address meets the criteria of that particular level. For instance, checking the syntax of an email address is a test of checking the validity of the address and would be a part of some pass.
  • Verifalia has set up three quality levels, based on how many passes it will subject the email address to: Standard Quality, High Quality and Extreme Quality. The Standard Quality, which is satisfactory for most requirements, has 1 pass while the Extreme Quality level has 9 passes. 

Three price bands: 

Unlike other email validation platforms which offer uniform quality bands, Verifalia has three price bands,  based on the level of quality you require.

  • Here, each email verification will use a certain number of credits. For instance, the highest quality level will use 0.04 credits, while the standard quality level will use 0.008 credits. 
  • In other words, the price for the highest quality email list cleaning is 5x the price of standard quality email scrubbing.

Temporary mailbox unavailability: 

  • Verifalia can detect downtimes of recipient servers and will retry email validation.

Multiple Anti-tarpit times: 

  • Verifalia allows an anti-tarpit time between 5 seconds and 2 minutes, depending upon the Verfalia’s pricing plans you’ve chosen.

Verifalia Pricing 

As mentioned earlier, Verifalia offers three price bands, depending upon the quality of verification you choose. Here’s Verifalia pricing for some of its popular packages in the basic tier: 

  • 5,000 verifications: $29
  • 10,000 verifications: $50
  • 50,000 verifications: $219
  • 100,000 verifications: $389

Why choose Verifalia

As an email verification platform, Verifalia offers all the standard features, for mailbox existence checking to disposable email checking. 

However, given their complex pricing model could turn off users. That’s because unless there’s a very, very clear value proposition, customers see no reason to pay a heavy premium that Verifalia charges.

How we’ve rated the services

From our own experience as well as from our conversations with other email marketing experts, we’ve found that not all factors are equally important when you evaluate email validation services. Some factors, like email data security, are extremely important, while other factors, like whether the service offers team accounts, are only moderately important.

We have based our comparison of email verification services on two groups of factors:

  • Critical Factors
  • Additional Factors

We found that four factors are extremely important so they have been placed under the Critical Factors category. All other factors are placed under Additional Factors. 

(You’ll notice some services have a third category: Miscellaneous Features. As the name suggests, Miscellaneous Features carry factors that are more like bonus factors; they don’t add any real value to the service).

Critical Factors

As mentioned above, four factors are critical to the overall effectiveness of the email verification process. They are:

1. Email Data Security

If the email list you submit to the email bounce checker isn’t secure, other factors don’t matter. From the point of view of the competitive scenario as well as from that of current data protection regulations, email data security is absolutely a critical feature.

2. Accuracy of Results

Your email checker should give you accurate verification results. Only if the results are fully reliable can you expect results from your email marketing campaigns.

3. Customer Support Available

The best customer support is the support you never need! However, there are times when you can’t get an integration to work right or you have a question about your special requirements. 

At that point, you need customer support the most. A service that provides timely and dependable support adds lots of value to your email verification exercise.

4. Pricing of Service

When you have only a few thousand email addresses to verify, pricing may make a difference of only a few dollars. But when your email list runs into a few million, the pricing difference is certainly an important factor. 

Remember, pricing is one of the four critical factors, but not the most important one.

Additional Factors

Here are some of the additional factors you need to consider when you wish to select out of the many email verification tools:

  • API availability
  • Auto-correction feature
  • Email data append
  • Email duplication removal
  • Free trial
  • File formats
  • Integrations
  • Scalability
  • Turnaround time
