Top 10 Bulk Email Verification and Validation Services Compared

What is a Bulk Email Verification Service?

Bulk email verification – an indispensable tool for companies sending mass emails – determines whether or not a list of email addresses is fully valid and deliverable. The process involves an address-by-address analysis of each email on an uploaded list and is offered as hosted software.

How Does Email Address Verification Work?

The legitimacy of an email address can be measured through a combination of validation techniques and – depending on the internal database – proprietary algorithms.

At the end of the list validation process, any invalid addresses will have been filtered out, leaving a clean, fully deliverable email list, ready for marketing and business requirements.

Below, we’ve described in detail just how the email validation process – essentially, a process of separating the wheat from the chaff – works.

  1. Email Address Syntax Check: This removes improperly formatted email addresses, according to IETF standards.
  2. Domain/MX Records Check: This verifies the DNS entries of an email address. If a domain is found to be invalid, or an MX entry is missing, this process marks the corresponding email address as invalid.
  3. Role-Based Account Detection: Email sends to role-based such as [email protected], [email protected], [email protected], [email protected], etc. can negatively impact your deliverability, and even blacklist you with some ISPs. This process detects and flags such addresses.
  4. Disposable Email Address (DEA) Detection: Throwaway/disposable email addresses, or “junk collector” email addresses,” are detected and processed
    appropriately. These are usually used for signup forms or to bypass login forms which require a valid email address.
  5. Honeypot/ Spam Trap Detection: This detects spam seeds, BOTs, honeypots, blacklisted, or bogus email addresses by checking the addresses in the list
    against the known list of email addresses/domains, used for trapping spammers.
  6. Checking DNSBLs and URI DNSBLs for blacklisting: A DNS-based blackhole list (DNSBL) or Real-time Blackhole List (RBL) is a list of IP addresses often used for spamming. A URI DNSBL is a DNSBL that lists domain names which have been found in the body of spam email messages but generally, have not been found inside legitimate messages. In the process, email addresses and IP addresses are checked against known DNSBLs and URI DNSBLs to trap spam networks.
  7. Final Verification: This phase performs deep-level extended SMTP verifications on each email address. The addresses will be pinged for mailbox existence without sending an actual email to the inbox.

Why is Email Address Verification So Important?

Most websites have forms asking for customer details, including an email address. While filling out such forms, it’s not uncommon for users to enter an incorrect email
address – whether intentionally or by mistake. All those incorrect email addresses added to your lists will be inaccurate – and undeliverable.

If you send emails to such addresses, the ratio of bounce-back emails will increase significantly. This bounce-back negatively impacts your mail server reputation, which is constantly monitored by Yahoo, Gmail, AOL, Hotmail, and other ISPs.

If your IP address develops a poor reputation, it may get blacklisted by popular email services like Gmail and the like.

This means that if you plan to run bulk email marketing campaigns, such as newsletters or sales emails, the identification and removal of invalid email addresses is essential.

Email verification ensures your email list is clean and thoroughly valid, which helps reduce bounce-back, ultimately saving you time and money.

Validating email addresses also helps you to maximize deliverability of your marketing campaign, and separates low-quality addresses from high-value contacts.

By harnessing the power of email list validation services, you can enjoy peace of mind with every send, knowing your emails go out to real, live humans.

    Hi Rahul,

    Mail Box Validator(our company) is providing email list scrubbing service. We will be glad if you can also evaluate our service. Thank you.

  2. Victor says:

    We have been using Email Answers for about a year now and I would recommend their service. They’re really nice people to work with and seem to care about their customers. Pretty rare in today’s Internet economy. They also have a new platform called Purelist for real-time list scrubbing.

    mailboxvalidator provides organization for integration with your mailing client delivering marketing information to targeted audience

  4. Micheal Loy says:

    Hello Rahul,

    I honestly think that BulkEmailChecker 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. They are the best bang for the buck, I hope you will revisit that company and see the amazing results such as myself.

    • Rahul V says:

      Hi Michael,

      Thank you for your feedback. The list here provided is a random list.

    • Joan says:

      Michael Loy, Thanks for suggesting Bulk Email Checker. After looking many services. I picked them also. I asked a pre-sales question and they responded in 15 minutes. Plus they are very affordable. Thanks again.

    • Jimmy says:

  5. Roshan says:

    Our products can treat about 10 millions address by day if necessary, and can treat protected mails like or which are using sender-verify technics.
    Best regards.

  14. Bill Kaplan says:

    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 blocked and/or blacklisted 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.

  15. John says:

    I used Bulkemailchecker 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 address does not have a valid dns.

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

    • Omer Sharif says:

      Yes man this is kind of common when your list contains non free corporate domains idz .Best way to check those idz if your list is small. Mix them with known valid yahoo/gmail/hotmail idz & shootout a test campaign with a free mailchimp account (Upto 2000 contacts) & you’ll get the best possible result!

  16. Eric Londo says:

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

    • Son says:

      Can you tell me a little bit more about bdwebit Email Verifier? What’s its feature? Can it detect spam trap, honeybot,…? Is it effective? And if possible, would you please show me the screenshot of this software? Thank you!

  17. Jim Warren says:

    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.

  18. Scotty says:

    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.

  19. Abhishek says:


    I recently validated my few emails through mybulkemailverifier its awesome!!!

  20. Arpit Agarwal says:

    Hello Rahul,
    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.

  21. Todd Steininger says:

    Hello Rahul,

    Thank you for the informative article and for providing the large list of vendors. I am currently using emailverifierapp dot com to verify emails 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?

  22. Jamie says:

    Love bulkemailchecker dot com

  23. Scott says:

    we have been using the 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 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 bulkemailchecker provided the fastest responses.

  24. Jo says:

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

  25. Jordan Brown says:

    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

  26. Jeff Straight says:

    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.

  27. Rajesh says: is not reliable. 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 .

  28. Vincent says:

  29. Neus says:

    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?

  30. Rahul says:

    Hi Neus

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

  31. Stephen says:

    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 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.

  32. 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.


  33. Carl says:


    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 http://Www.QuickEmailVerification.Com and became aware of some of our clients who have this config. Specifically those who route their mail through websense.

    • Nikolai says:

      Actually to identify accurately if email is “accept all” or not is also an advance feature! I believe that there is no other option to verify “Accept All” emails with 100% accuracy. Based on amount of “Accept all” emails in your list you can plan your strategy to send email campaign. After comparing some best-in-class providers in the above list (Thanks AccuWebHosting), we’ve been using for last four months now and have been satisfied with that service. There are many providers but very few of them having best accuracy of the service. And from those accurate service providers, only QuickEmailVerification’s price meets best to us. You may also find the one which meets with your needs from this list!

  34. Anna says:

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

    • Petko Ichev says:

      Proofy dot io doesn’t serves its purpose well and is full of problems:
      – we have been billed 3 times to withdraw a single list of checked mails
      – One check returned status “undeliverable” for all emails in it, which by no chance is not true, cause the same list was tested in 3 other services as well.
      – Their support is **** . We issued like 4-5 notifications/tickets to their support – recieved so far 0 feedback (3 weeks so far)
      – Their statistics before withrdawal of a list are buggy as well – e.g. from a list with 3000 mails, the statistic contained 1500 emails with certain status, after downlowding the actual list, what a surprice! all entries had a status; another e.g. very often after a check is done once the statistic shows xx% pricocessing, after log out and log in – yy% processing.

      You are free to draw your own conclusions. For us – one of the worst services, we’ve used.

      • Support says:

        Hello, Petko!
        We are very sorry for this situation
        In last few month service Proofy changed all support team
        We want to see what problem do you have and we ask you please send your user ID and email from proofy account

  35. Jennifer says:

    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!

  36. Mick says:

    Thanks for this great list of 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


  37. Hiren says:

    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?

    • Patty Drake says:

      Hey Rahul
      Great post! I wanted to test and compare services and this post gave me a lot of options!
      I have been into email marketing for a few years now and I have learnt an important lesson: never use email lists that have not been cleaned. MailChimp once suspended our account and man, did we have a hard time, getting it back in action!

      So while comparing services listed here I used criteria like Accuracy, Support, Pricing and Speed, mostly in this order. While no service can score 10/10 on every criteria, I think (currently # 3 in this list) makes most sense. I was particulary impressed with its Accuracy and the Support. I first used their 100 free validations and found the output was highly accurate and quick. I shot a querry to their Support (like I did for every service I tried) and QuickEmailVerification’s reponse was most helpful. And of course, their Pricing is extremely competitive so you don’t have anything else to think about.

      Of course, you may want to check it out yourself and not take my word for it – go ahead.

  38. Clay says:

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

    • Rahul V says:

      Thanks Clay for reaching out. Try out any of these – QuickEmailVerification, Hubuco & xVerify. They have responsive dashboard. You can access it through your mobile device, upload email list and download cleaned list. Also, Email YoYo has launched their mobile application for email cleansing. You can also consider them.

  39. Jonas says:

    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.

    • Rahul V says:

      Thank you, Jonas! We review many providers at regular intervals to update our blog with the best providers.I can suggest you looks similar to Datavalidation.

  40. jeroma says:

    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.

    • Rahul V says:

      Yeah certainly. You can choose either of these QuickEmailVerification, Hubuco or BriteVerify. These providers have good track records in cleaning free email providers.

  41. Asgar Ali says:

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

  42. Surya says:

    Can anyone personally recommend the tool. We used the but campaigns where not that great.

    Look forward for some recommendation

    • Rahul V says:

      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.

  43. Jim Carter says:

    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?

  44. Laura says:

    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 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.

  45. Laura says:

    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.

  46. Hi,

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