We have been using Email Answers for about a year now and I would recommend them for email list verify service. They also have a new platform called Purelist for real-time list scrubbing.

Hello Rahul,

I honestly think that Bulk Email Checker at #8 should be ranked much higher up on the list. With their 95% deliverability guaranteed quality of their email validation services coupled with all of their additional features and affordable pricing, compared to others they really are much better than most of these companies. I have tried 6 or so from this list and after visiting Bulk Email Checker my search stopped as I know I can not find better at this time.

You seem to have missed out one of the best email verification apps that I have used – emailverifierapp. I think your visitors would find it resourceful. But good list there. Well done compiling them into one big list. These services are helpful indeed.

This company (lead-factory) also offers database cleaning API.

How were we left out? We have been in the game longer than most of the companies on this list, we do over 300,000,000 a month. We can give you a free bulk email verification trial to test out our service if you would like.

I use mycleanlist and they are very good too… And I found them cheapest email verifier by price among of all of above…. give it a try…

Hi Rahul, have you listed this email validating softwares rank wise or just randomly?

Is there any Indian company which provide email verification service, i am looking for low cost email verification

Great list!! I am looking to become a email list cleaner. Can you recommend a good email list verifier software reseller. We would love to find a good software to buy.

Would love for you to try out and evaluate YouVerifyIt’s email verification service. Our founders have been in this space for a decade and have built a phenomenal email address verification engine that is soon to be released! Just fill out the contact form and we can get you started!

We can make an offer to you in order to clean your mails. validmail.fr can validate about 99.999% of email address for you. Our products can treat about 10 millions address by day if necessary, and can treat protected mails like free.fr or online.fr which are using sender-verify technics.

If one is simply looking to ping (i.e. perform an SMTP check) on email addresses, which is what the companies listed above all do, then you’re not going to be solving your deliverability problems.

Deliverability issues are the result of three main factors in the following order of priority:

The existence of spamtraps and/or honeypots
Excessive spam complaints – .3% (i.e. 300 complaints out of 100,000 sends) is the typical threshold used by ISPs.
Exceed this threshold and a dynamic block will be put up, preventing the delivery of any future emails for 24-48 hours.
Exceed this multiple times and you’ll find yourself deined and/or blocklisted for good.
Exceeding bounce rate thresholds – 10% is the typical threshold used by ISPs but this can vary significantly across ISPs, some of which are also factoring engagement metrics into this calculation and their determination of whether or not you’re a worthy sender.

Pinging is discouraged by many ISPs, which will shut down attempts over a certain number or provide back inaccurate information so any service that simply performs pinging only might result in more issues than you first started with as you will end up throwing out good addresses with the bad. Furthermore, pinging an email address, even if this could be 100% accurate, will not flag spamtraps, honeypots, heavy spam complainers, “role” accounts that go to multiple accounts, and other malicious addresses that can destroy one’s email program.

Accordingly, marketers need to employ a service that blocks deliverable but toxic addresses, corrects hygiene errors, and validates all email addresses that survive the first two screens. Doing this properly requires expertise, experience, technology, and a knowledgebase built over years of reviewing billions of email addresses.

I used Bulk email checker for a list of about 1,000 emails that from my business contacts. The user interface was very easy to work with and the dashboard is nice. My only issue is that 54% of my emails came back as “Unknown” with the following messages:
The address does not have a mx server.
Is a Catchall mx server config.
The email address does not have a valid dns.

Is this common when you have a lot of corporate email domains?

I use bdwebit dot com their SMTP and Email verifier is too good. I am using their service from last 3 years.

Hi, I recently purchased a US business database close to 500K executives and soon after my 1st campaign my mailing account was locked. Can you suggest a good email verifier to remove invalid, spam traps, catch all and other possible troublesome emails? I’m confused with the options available and dont want to be spending another bomb on this database.

An excellent article Rahul. Thank you so much for putting together a list of some of the verification vendors. We recently evaluated several vendors for verification and have found most of them to all offer the same thing. Let’s face it, verification is a commodity. Webbula is someone I noticed that wasn’t on your list and we found their service offering to be excellent because not only do the offer the same verification services as everyone else, but they offer hygiene services to identify moles, traps, complainers, and other toxic emails. That won us over.

Nice to see your post which is very help full for all the fraternity in email marketing domain. We are an Indian startup and recently launched our venture in the same domain as verifyemaillist dot com. I request you to please evaluate the same and if possible please cover it in your any existing or upcoming article.

Hello Rahul,

Thank you for the informative article and for providing the large list of vendors. I am currently using emailverifierapp dot com to bulk verify email address in my opt-in forms since January. Their service is top notch as I have experienced a 100% uptime, an average bounce rate of just 0.33% and their speed is so fast my subscribers do not even realize their email is being verified in realtime.

I am curious as to why they have not made this list of vendors since the service they provide seems to be a perfect fit?

we have been using the bulk email checker api and are fairly pleased with it. Price wise it is less expensive that others and as far as quality and speed, I was not able to to detect any difference between bulk email checker KickBox.com as far as accuracy of the data.

The user interface is a little odd – feels incomplete – can’t search the hard bounces, when exporting hard bounces they come back as 1 row (normally I would expect the data to come back 1 row per entry) and a few other things like that.

Support has been responsive and have answered questions within a few hours. I contacted support for several others and they provided the fastest responses.

Thank you for the article. Email Hippo validates Yahoo addresses, it’s the only service that does this.

Experian Data Quality has the best validation services in the game. Shoot me an email and I can set you up with a free data test and show you how it works – jordan.brown at experian.com

I can’t believe you don’t have emailverifierapi dot com added to this list. Out of all the services you have listed, Email Verifier Api is the only enterprise grade service. I don’t want to deal with issues, so enterprise grade quality is the only acceptable services.

Emailverifierapp.com is not reliable email list verifier. I bought a package of cleaning 100000 email but it cleaned only just 25000 email and rest 75000 was not cleaned. Issue was intimated to Support team . Its 5 days since issue happened and they are not able to fix.

So be careful and better to go by small volume packages to ensure that the service and product works fine.

I am now looking for another email list cleaner.

We are looking for a company who can give officially approved document about that the verified e-mail addresses are really valid and checked.
Do you know any company like that?

Hi Neus

We at Locate Ventures pvt ltd can do that. Check out locateventures dot com

Thanks for collecting all services together. It helps to compare services but some of the features listed above for some services are not available. Even they do not provide what they claim for on their website. We’ve been using daily credits plan of https://myemailverifier.com for more than two years now. Excellent service and support. It is Enterprise level service designed for both large and small businesses. We have already compared many other service providers in the above list and have also tried paid service from some of them but we could not get the accuracy we expected. Nearly zero bounce rate was our primary concern since we have been using MailChimp for sending email campaigns. Due to high bounce rate our account had been suspended by MailChimp and we had very hard time to get it fixed.

Hi,
I would like to recommend our new application HuBuCo
– Fast online validator, one by one, bulk uploads and API.
– Very competitive pricing: e.g. $19 for 10,000 emails
– Refund your credits for Unkown like catch all and anti spam systems

It would be great if you tried our system (also offer 500 free credits to try) and left your comments.

Thanks

Hi

Great article.
Question: Is there any way to verify an email address if the server has been set to “accept all”.
I am busy testing https://CaptainVerify.Com and became aware of some of our clients who have this config. Specifically those who route their mail through websense.

I found this service proofy dot io as most accurate and obviously the best one on the market.

I used HuBuCo for verifying my email list and it was very easy. It allowed me to quickly get a very accurate list of ok emails, bad emails and even emails that forward to other addresses (so if a recent contact has left a company, I will know if the email is being forwarded or if it was just deleted from that company’s server). I scanned over 10,000 email addresses and the verification was completed within 15 minutes. Very easy and when I had questions, customer service was quick and easy to work with. They even offered help with a piece of the process they had no control over, which was very nice of them and makes me feel very comfortable recommending them as my #1 choice for verifying email address lists quickly and accurately. Hope that helps!
Jennifer

Thanks for this great list of bulk email validation tools.

In the past, I’ve used some services of your list like Briteverify or DataValidation, but recently, I’ve switched to nojunk.io which is quite new but I think it has the best RoI :

• results are similar to other’s, but I didn’t try them all
• it’s cheaper than most of them

Thanks again, this list helps a lot to discover and try new email validation services and I hope you’ll have great results with nojunk

Mick

Hi, This blog is just phenomenal. I came across another provider: verifalia dot com. They provide 125 validations / day for free. Any experience with this provider?

This is a great article. Are there any email verifiers that support mobile apps integration and also if we can get update via mobile for our cleaned list and download list etc.

Hey Rahul, I must say its a great compilation. I had used datavalidation in past and they had been excellent so far but I am willing to cut short my budget. Can you suggest us similar provider with affordable pricing? Thanks.

Hello Rahul, Great detailed article. I want to clean my generic free email provider list like Yahoo, Gmail and hotmail. Can you suggest a provider.

Thanks for the great share. Most of the listed providers here offer limited free trials. I need an email verifier who can offer unlimited free email validations forever. Can you suggest any?

What was the problem with QuickEmailVerification campaign? We’d recommend any of top 3 email validation providers, i.e., Xverify, HUBUCO, Towerdata and Kickbox. You can choose as per your budget and requirements. It’d be better to take a free trial before signing up. Best of Luck.

The list and details are superb. Do you know any of the email hygiene provider which provides a WordPress plugin kind of solution, so even a non technical person can also use it. I know API are available but just wondering if any ready to use wordpress plugins are available?

This is a really helpful list Rahul, thank you. Could you clarify whether you have listed it in order of those you think perform the best, or is there no rationale for the order? I notice that some email verifiers at the top don’t have some of the features those lower seem to offer. Also, it would be amazing if at some point you could compile a table with checks / crosses next to features offered – would really make comparison easy.

Just an FYI, I’ve been running tests with each provider that offers free tests. Mailbox Validator marked every hotmail email as invalid, which is not the case.

Hi,

Any email verification vendor GDPR/PrivacyShield certified? Thanks in advance!

Hello Tammina, CaptainVerify does not provide completely free email verification. Their charges start from $7 for 1k email verification.

Of the services listed here I found #1 and #3 the most effective. Another one I’ve been using is mail mule – I think they’re a little new but the service is really good. The support team is especially supportive which means its probably quite well managed.

So far in terms of quality mail mule, hubuco and emailchecker are good. Of all of these in pricing terms I think mailmule is the best. My own 2c naturally. I send out a fair few emails for my site and it helps to have a reliable verification service.

This is a really helpful list Rahul, thanks. We have just started to use a new online service from WinPure, its called Email Verifier Pro – emails dot winpure dot com
They provide both bulk email validation and an API which can be used on webforms, forums and signups.

Hi Rahul ,
Please evaluate emailexistdotcom, we recently launched beta 1.0, Tool to verify whether email exists in real world. It extracts the MX records and other proprietary techniques and strategies from the email address and connect to mail server to make sure the mailbox really exists for the email Id.
It validates :
– Syntax
– Role-based
– Mail server
– Disposal Emails
– catch-all
– Server status
– Spam Rate Calculation
and use proprietary techniques and strategies from the email address

Our custom API provides email verification for single and bulk emails which can use within your application, we had done with PHP library and more on the way to come .

Note: Website is going to updated in few days

I think you should look at bouncekick.com, i have done email marketing for the last 13 years, and always looked for a selfhosted email validator – I came across this product and purchased with a one time payment of $1500, even though the system currently missing a few features their team is really working hard to make new releases of the software currently they release new updates every weeks!
I mean validating email databases can be a costly affair, and with a one-time payment i must admit that this software really gives you value for the money – Besides that its the first selfhosted email validation software i have ever found.

Thank you for verifying and adding emailverifier.com, after testing a lot of different tools from the lists above I settings with Emailverifier. The reason, simple. I pay $300 per lead over adwords, so I cant really afford to lose leads due to false positives, their 99% accuracy guarantee was attractive but in all honesty the reasults are very accurate

Another one great solution is truemail.io.
Convenient, easy and fast email verification tool. By the way, it has free trial and you can verify your first 1000 email for free.

I really like Zerobounce.net – i think they are the most accurate

This is a nice list of email verifiers and I can see a good amount of effort that has gone into the blog. I would appreciate if you can add antideo.com to the list as well. Antideo is an API service that helps user to do a live detection of disposable email addresses and the list is auto-updated so that you always stay ahead of the curve. And the icing on the cake is that a user can make upto 5000 API/month for free.

I’ve been using email verification services for a while, and one service that stands out is mail check. It offers high-level email validation with top-notch accuracy, making it a powerful alternative to some of the more established names in this space. The platform provides detailed verification reports, and the API integration is seamless. If you’re looking to improve your email deliverability and maintain a clean list, mail check is definitely worth considering!

Great comparison! I’ve used a few of these services like ZeroBounce and MillionVerifier, but recently I tried PureChecker, and it seriously impressed me. It’s the world’s fastest email validation checker — able to process 100,000 emails in just 2–3 hours via file upload. Super efficient, and the pricing is much more accessible for smaller businesses. Would be awesome to see PureChecker included in future updates of this list!

I found this article super helpful! It’s crucial to have a reliable email verification service to keep our lists clean and improve engagement. Thanks for sharing these insights!
