   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.

    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?

    Reply
• Omer Sharif December 28, 2015

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

    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.

    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?

    Reply
19. Scott May 27, 2016

    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.

    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.

    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

    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.

    Reply
• Nikolai October 26, 2016

  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 http://quickemailverification.com 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!

• Petko Ichev January 24, 2017

  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.

    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!

    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

  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
  https://www.millionverifier.com/ 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 MillionVerifier’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.

    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.

    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.

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.

    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!
