Top 10 Email Verification Software & Tools 2022

At its most basic, email verification software tells us if an address is valid or not.

However, with the right features, it can provide much more value – whether you’re in the marketing, operations or risk management department. Let’s take a closer look.

List of Best Software Verification Tools

What Is Email Verification Software?

Email verification software lets you automatically check if an email address is valid or not. It’s a tool frequently used by marketers and sales teams to ensure their emails are received. This is to avoid email “bounces” which point to junk leads.

The rates at which recipients open marketing emails tend to be low worldwide, averaging 16–20% in 2020, according to Statista.

Marketers use email verification software to ensure their emails are at least deliverable. This helps reduce the costs of sending newsletters and email marketing campaigns.

Sophisticated email verification software also lets you extract more information about the email address, such as whether the domain is free or paid, and whether the email address owner has social media accounts. This makes email verification software a great tool when considering who to funnel into KYC processes, as well as for fraud prevention

Top Email Verification Software Features

Email verification software should, at the very least, tell you if an email address is valid or not. But there’s more to consider:

  • Scalability: How many addresses can you check at once? Ten? Ten thousand? For ambitious businesses, you must ensure the tool can grow along with your needs.
  • Real-time results: Admittedly, for a marketing campaign, it might not matter if there’s a little delay before you get your deliverability results. But for KYC or fraud prevention, though, you need results in real-time. More to the point, the results must come from fresh data, not ancient blocklists (as the latter could lead to false positives).
  • Setup and integration: While most email verification software comes from SaaS companies, more complex solutions can also work via API. This is ideal if you want to speed things up and automate processes – as long as the integration time isn’t punitive.
  • Reliability: Checking email addresses, like sending emails, requires decent server uptime.
  • Pricing: Most email verification software providers offer a free starter plan. Be mindful of the limits on the number of checks you can make before they bump you up to more expensive subscription tiers. 
  • Extra features: While email deliverability is the cornerstone, you’ll need more features for KYC and email profiling. For instance, technology to help you understand how legitimate the user appears to be, whether they’ve had the address for a while, or if they’ve used it to sign up to online services such as social media.

The Best Email Verification Software of 2022

Whether you’re looking to boost your marketing efforts or get a 360° view of your users, here’s our list of the best email verification tools of the year.

SEON is a fraud detection company that delivers powerful data enrichment. In the context of email verification, this means getting tons of information based on an email address only. 

Of course, you get real-time deliverability checks via real-time SMTP-MX checks, but also a lot more:

  • Email address maturity: SEON relies on email data breach data for user verification. This is a fantastic way to confirm if an email address is in use, and how long it’s been active.
  • Social media registrations: Email addresses linked to social profiles proves that the user actively uses them. Not to mention all the valuable data you can glean from checking the public sections of the social media profiles themselves.
  • Domain information: Is it free to create an email address with that domain name? Are there any security checks? If the answer is no to both questions, it’s more possible you’re not dealing with a high value client – or worse, it could be a fully-fledged fraudster.

Examples of data you can get with the SEON email API

The real advantage of SEON is that you get all the results in real-time and integrate the tool however you see fit. That includes APIs (as pictured above), but also manual lookup and even a Google Chrome or Shopify extension. 

  • SEON pricing: You can start fighting fraud, learning more about users, and getting extra data based on an email address, phone number or IP address for $99 per month. And there’s a completely free trial to get an idea of what SEON can do!


Zero Bounce Logo

The first thing you should know about ZeroBounce is that it claims a 98% accurate email validation rate. The company also offers blacklist monitoring tools and even email quality scoring to assess whether the address is active or not.

ZeroBounce is the email verifier of choice for renowned companies such as Hotjar, Samsung, and Airbnb. You can test a single email address on their website but you’ll need a subscription to check more than 100 emails a month.

Pabbly Logo

Pabbly takes an interesting approach to email verification: slower is better. For these email specialists (the company also offers newsletter services), that means a higher accuracy rate when verifying email lists.

Of course, the downside is that you have to wait for the results. For marketers who only need to scan their lists for deliverability issues, though, this could be a sacrifice worth making – especially as you also get features such as syntax elimination, domain confirmation, and duplicate removal.

  • mailfloss pricing: You get a free seven-day trial. After that, it’s a three-tiered pricing system, starting at $17 a month (10,000 scanned emails) all the way up to $250 a month (125,000 scanned emails).

snovio logo

Snovio (also known as includes all the features you’d expect for good email marketing, including email address validation and email finder. The deliverability checks come courtesy of the standard real-time SMTP-MX checks, available via API or bulk upload. 

While the pricing is competitive enough as it is, what sets apart is the quality of its customer service – which is constantly praised by users. And the integrations aren’t half-baked either, with support for more than 2,000 other providers, including sales tools, teamwork apps, and form builders.

  • pricing: works via a credit system. Each email verification costs half a credit. You get 50 free credits a month (100 email checks) and five monthly plans, ranging from $33 per month (1,000 checks) to $615 per month (100,000 checks).

On the verification and validation side, Hunter has Email Verifier, which relies on a proprietary system to “return a result even when other standard verification tools would fail”.

One key feature of Email Checker is the ability to remove email addresses from temporary email providers. You also get syntax correction – for example, turning into 

  • Email Checker pricing: It starts at $30 for 5,000 email credits, or you can pay $25.5 for the same features but with a monthly contract. After that the price goes up depending on usage.  



Clearout is an email verification solution that specializes in removing unwanted emails from your lists. Detection methods allow you to clean up subscriber lists by removing duplicate emails, syntax errors and temporary email providers.

Another full-featured email verification tool, EmailListVerify claims to achieve the same results as its competitors for half the price. Starting at $4 to check 1,000 emails, it seems on par with other providers’ pricing – but things get interesting when you get to higher volumes.

Choosing the Right Email Verification Software

Email verification software, at its most basic level, will tell you if an address is valid or not. You can also clean up your lists using syntax verification, duplicate removal, and even by scanning for temporary email domains. 

But email addresses are also a fantastic data point to learn more about your users. By leveraging reverse email lookup at the onboarding stage, for instance, you can learn a ton about your users – whether it’s to boost KYC, improve compliance, reduce chargeback rates, or simply keep your business safer.

What is the best way to verify an email address?

You can perform what’s called an SMTP-MX check to ensure the inbox exists and will receive your email. Most email validation software offers this feature. Of course, you can also test it manually, making sure that the syntax and domains seem valid. 

What information can I get from an email address?

You can learn if the address is valid or not, check if it’s from a paid or free domain provider, and see if it’s connected to any online platforms, including social media.

How do I bulk verify email addresses?

For bulk verification, it’s helpful to rely on email verification software, which can check thousands of addresses at once. The results are either checked automatically (if you connect the tool with your mailing list provider), via API or as CSV.
