    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.

    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.

    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.

    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?

    Reply
    • Omer Sharif December 28, 2015

      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!

    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 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?

    we have been using the bulkemailchecker.com 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 bulkemailchecker.com 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 bulkemailchecker provided the fastest responses.

    Emailverifierapp.com 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 .

    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 http://QuickEmailVerification.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 http://Www.QuickEmailVerification.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!

      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!

      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
      http://QuickEmailVerification.com (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.
