5 Battle-Tested Email Verification Systems

In this day and age, the power of email marketing is no secret. However, marketers seem to forget one of the most critical components of this process – an email verification system.

Using an email verification service will not only allow you to save money by emailing those who have a valid email address but will also help to increase your email deliverability and help your sender reputation.

In this post, we’ll dive into what an email verification system is, how it helps your business, and give an overview of the top 5 tools on the market that you can use today to verify your email lists.

Let’s get started!

What is an Email Verification System?

An Email Verification Tool is a tool that will verify a list of emails that you used to contact your customers. It determines whether or not a list of email addresses is valid and deliverable.

The process involves a one-by-one analysis of each email address on an uploaded list, usually through a third-party SaaS tool. The legitimacy of said email addresses can be measured through a combination of validation techniques and algorithms, The Email verification systems evaluate the list to filter out any invalid addresses. Thus leaving behind a cleaned up and fully deliverable email list ready for your business and marketing needs.

How does an email verification system work? Well, it follows a pretty structured process which I’ll describe below.

  1. Email Address Syntax Check: This will remove improperly formatted email addresses.
  2. The Domain Check: If a domain is found to be invalid, or a mail server entry is missing, this will mark the corresponding email address as invalid.
  3. The delivery Check: Most email verifiers will also connect to the email server and attempt to send an email. They won’t actually send it but this process usually is enough to understand if an email address exists on a given domain name.
  4. Role-Based Account Detection: This will flag e-mails sends to role-based email addresses such as postmaster@, info@, admin@ etc. (which can negatively impact your reputation and even blacklist you.)
  5. Disposable Email Address Detection: “Throwaway” & “Junk” email addresses are detected and processed out.
  6. Spam Trap Detection: This detects spam, BOTs, blacklisted, or bogus email addresses by checking the addresses in the list against the known list of email addresses and domains.

Why You Need an Email Verification System

Running your mailing list through an Email Verification System is an important step to being able to make sure your offers and messages are reaching everyone on your list. There are several reasons why you should be using an email verification system before you send out that mass of e-mails.

An email verification system improves your sender reputation by reducing the number of spam ratings and helps to prevent blacklisting, and ISPs sending your emails to the spam/junk folder instead of inbox.

It also allows you to reduce your email marketing costs, as you don’t pay for contacts that are fake or can’t receive emails at all. In fact, a whopping 16% of emails never even make it to the inbox. That’s almost a quarter of your emails (and advertising dollars) wasted.

Yet another benefit of using an email verification system when you have a more accurate representation of your performance metrics (like sent and open rates) as your contacts are certifiably genuine. This will allow you to create accurate benchmarks and reporting for your next email campaign.

Now – onto the tests!

5 Battle-Tested Email Verification Systems

In this article, we will be addressing 5 email verification systems that have free trials to put them to the test. We will be testing out some of the newest systems to the arena like Breadcrumbs and Bouncer alongside some older and better-known systems like Zerobounce, BriteVerify, and NeverBounce.

We used a list of compromised of 50 e-mail addresses where 40 Emails were real, 4 were created with disposable mail services like @temp-mail.org, @mail.tm, @fakemail.net and @Tempmailin.com. Our next disqualifiers where spam traps where the domain was real but the email isn’t valid, For example, ihopethisemailaddressisntreal@gmail.com.

Let’s get to the results!

Email Verification System #1 – Breadcrumbs Email Verifier

The beta version of Breadcrumbs is already on top with the results of their email verification testing.

Email Verification Results
Real emails: 40/40
Spam traps 5/5
Disposable mail: 4/4
Typos: 1/1

Breadcrumbs is brand new to the game and it’s actually addressing a way bigger problem. They’re building a Revenue Acceleration platform that sits between Marketing, Sales and Customer Success. Their email verifier is a free tool they’ve released on their website as a gift to the community.

We loved that you could access the full report with a detailed breakdown online from your browser, and even share the link with your clients or coworkers. This definitely kept it as a seamless experience without bogging us down with multiple downloads. Breadcrumbs have our attention for it’s easy to understand, fast results, and perfect accuracy.

I personally loved the ranking system in place, there was a lot more information about those same 50 e-mails than I saw put forward through the rest of the e-mails in this test. Very impressed with the attention to detail allowing you to really weed through who really is worth e-mailing or if you’ll be putting your account’s reputation at risk.

We just had to share this ranking system, all available right on the page, from Breadcrumbs’ service.

At the end of this analysis, you also have the ability to download the problematic emails to a .csv folder for safekeeping. Right now Breadcrumbs only supports single email input or by connecting your Hubspot account, however, support informed us that Mailchimp and other CRMs are on the horizon.

Email Verification System #2 – ZeroBounce

The next email verification system we put to the test was ZeroBounce. ZeroBounce wasn’t a bad service, but it took multiple approaches to get the results we needed and were looking for.

Email Verification Results
Real emails: 39/40
Spam traps 5/5
Disposable mail: 4/4
Typos: 1/1

Initially, we used a free (and valid) email from Google to register. We found out right away that while they accepted the email address to test out their email verification system, they only allotted us 5 credits for the free trial. That’s only 5 emails to verify.

This wouldn’t be very helpful for someone just starting out or who hasn’t converted over to a business email.

They did offer a monthly subscription option or to buy a one-off set of credits. We only needed to test about 50 emails here, but the minimum amount of credit we could purchase was $16 for 2,000 emails.

Then, we decided to follow up with a business email. In the business email we were given 100 free credits to run instead of 5. The initial test sheet came back completely blank. Not a single email had been caught, including the typo.

We decided to give ZeroBounce another shot by running the list again, and the success rate was significantly improved on the next report. While they did get 49/50 emails on the next test, the sole email that was filtered out actually one of the real ones.

Over-all we did not find ZeroBounce to be a very user-friendly system to use, and the results did not provide us much confidence for future use.

Email Verification System #3 – NeverBounce

As we move to the next tool on our list, we come to NeverBounce. Let’s see how they stacked up against their competitors.

The results of our test of NeverBounce’s email verification system.

Email Verification Results
Real emails: 37/40
Spam traps 5/5
Disposable mail: 4/4
Typos: 1/1

Right out the gate, NeverBounce will not allow you to sign up without a verified business email address. That at least narrowed down what we needed to run for our test of the NeverBounce email verification system. I couldn’t scan the same Excel spreadsheet we were using for a list without first converting the list into a single line CSV, which wasn’t difficult but was a little annoying.

Once converted Neverbounce took a minute to load and you can’t access your results until you opt to clean your list. This was a really handy tool until I noticed that only 37 out of the 50 emails were considered valid and verified. This should have been 40 out of the 50.

With higher numbers processed and an error that stretched into 3 of your 40 valid potential customers, you could imagine that margin would end up much larger as your list size grows. It also seemed to calculate the header column as an email, as the list says 51 instead of 50.

While NeverBounce was a free tool and easier to use than some others on this list, we’ve again incorrectly listed real contacts as spam which doesn’t give us the peace of mind we truly wanted within a tool such as this.

Email Verification System #4 – BriteVerify

BriteVerify is the next system on the block. Let’s see if they can outrank their competitors!

BriteVerify
The results of our test of BriteVerify’s email verification system.

Email Verification Results
Real emails: 37/40
Spam traps 5/5
Disposable mail: 4/4
Typos: 1/1

To use BriteVerify you will need a valid business email address. My understanding is you have to wait for a live representative to work with you and then download an app. Once you start the verification process through Validity you find that you’ve got to make sure you’re in the window of normal business hours and spend some more time waiting in a chat window to be verified. Beyond my brief conversation with a bot, I was able to take the time to literally make my family breakfast and in the time it took for a response.

Once I was finally cleared to go (after a few days of waiting) the first thing that pops up is information for my card. I’m only running 50 emails so that’s not too bad. It cost me a total of .50 cents, but, I feel like I was misled.

Taking another glance on the signup page, I notice the price isn’t mentioned until near the footer. Certainly nowhere on the top half of the page. While it is arguably very cheap, .50 cents to run a test isn’t bad, the test didn’t meet my expectations for this wait. It found everything it needed to as well as knocked out 3 more valid emails, much like the others.

Honestly, this seems like a lot of hassle to run an e-mail verification tool and we believe that it shouldn’t be this much time and effort (or even money) to run an email verification system test. The effort needed just to test the system did not install confidence in a future relationship.

Email Verification System #5 – Bouncer

Last but not least in our email verification test is Bouncer. Will it beat out the others in this article?

email-verification-system-bouncer
The results of Bouncer’s email verification test.

Real emails: 37/40
Spam traps 5/5
Disposable mail: 4/4
Typos: 1/1

Initially, I attempted to go to ‘Bouncer.com’ which quickly made me realize that I might have to look up the address as they seem relatively new themselves.

The email verification from Bouncer bounced right into my spam folder initially on a basic gmail address, however, I was able to sign up without the business email. That’s handy for those just starting out. However, instead of receiving a verification email, I was told that ‘Our growth catalyst will contact you in the next few days.’ with a follow-up video about their team. After another day I received an email with a verification code to sign up.

Though it did take some time to get set up, and some time to scan the list as it wasn’t the fastest scan I’ve encountered, Bouncer did a fair job at sifting through our email list. Unfortunately, Bouncer found 37 emails out of the 40 good emails to be deliverable, leaving us with a hit of 3 missing potentially paying clients.

Email Verification System Conclusion

Over-all these email verification systems ran well. They all caught what they needed to, often more than just the traps, snagging a few real emails in the mix.

One tool stood above the rest as far as seamless and speed. The upcoming Breadcrumbs system figuratively knocked the ball right out of the park.

After that, the next new-comer Bouncer did a fairly good job, the tools were simple and easy to use, but the sign up had some hiccups.

I wasn’t a fan of the dramatic differences from 5 to 100 credits to test out ZeroBounce but they’re coming up in 3rd as far as somehow being more user-friendly.

NeverBounce coming in fourth for requiring conversion of a file accepted by the other 4 tested email verification systems making it mildly inconvenient.

BriteVerify comes in last for difficulty signing up and just being able to even start the process, to instantly asking me for my card info against all the services that offer it as an add on as well as spending any money at all on the implied trial.

We hope this article has made the decision about which email verification tool to use a bit easier! If you have another tool you prefer to use, let us know in the comments below.
