Best Email Verification Services of 2025: Prices And Features

Best email verification services compared

Can’t choose an email verifier best suited for your needs? Looking for a comprehensive email verifier tool comparison? Want to find a tool with the best accuracy, price, and feature set? Look no further, because we’ve created this guide just for you. We will compare multiple parameters like price, free plans, verification methods, databases, APIs, browser extensions, additional tools, and tech support.

What is an email verifier?

Email verifier is a tool that allows checking a single email address or bulk email lists for being existent and valid. It may be represented as a desktop tool or an online service. The latter is more popular nowadays as it does not require using your IP address (you may run the process using different servers) and is easy to support or update.

The performance of every email verifier is based on specific inbound algorithms, which call for several steps of the email verification process. The most common among them are syntax, domain, catch-all, MX record checks, as well as email address ping. Email verifier helps control any changes within your contacts, keeping your email list clean.

Types of email verifiers

Email testers come in many forms and sizes, so it’s not hard to choose an email verification service based on your needs and business type.

Software email verifiers

Software email verifiers, like AtomPark, can be a good solution for larger businesses where one person will be in charge of lead list management, including verification. Besides, companies consistently working with large volumes of emails will also benefit from such email verifiers.

The pros are obvious: one-time payment, unlimited email verifications, and complete ownership of databases. However, there are quite a few cons to software email verifiers: update installment, need for backups (i.e., no automatic cloud storage), access limited to a single device, no integrations, as well as PC and OS requirements. 

SaaS (software as a service) email checkers

SaaS email checkers, like Snov.io, offer a cloud-based system. It lets you work right from the browser with all the data saved in the cloud and all the processing performed there. SaaS solutions usually use a subscription model with monthly limits on email verifications. Still, they always offer a variety of freemiums and plans to fit any budget

Such a model is perfect for those who don’t need to test emails all the time and are looking for a pay-as-you-go or one-time solution. Other advantages include unlimited access to your account and database from anywhere in the world and any device, teamwork options, no restrictions in OS, and APIs. 

Besides, often, SaaS email checkers are part of an all-in-one toolbox offered within one subscription. For example, an email verifier offered by Snov.io comes as a part of the email finder/verifier/sender/tracker bundle, all offered within a single plan, free or paid. 

It’s important to note that both email verifier types usually offer single email verification and bulk email verification. If you can’t seem to find a form of an email verifier that suits you, it’s a good idea to contact the verification service of your choice to find out what custom options they offer.

We chose the final seven by googling the most common keywords, such as email verifier, email verification, email checker, etc. This is what anyone looking for a verifier tool would do, and these are the results they would see.

What to consider while choosing an email verifier?

It’s always easy to choose between two options. But the market offers dozens of tools, and that’s where the task becomes complicated. Here are some tips on how to choose the best email tester.

Price per 10,000 email verifications

You might think, “The more you pay, the more you get,” but this is not always the case. Despite often offering the same level of service, the prices set by tools can vary from $50 to $2,000 per 10,000 verifications. Try to find the sweet spot to get the most out of the platform at the most suitable price.

Freemium

If you need an email verifier for an occasional email validity check or you’ve just started an email list of under 100 leads, you may want to look into services that offer freemiums. While tools like Snov.io offer 100 free email verifications per month, services like Hunter.io only offer 50 checks per month, while Anymail Finder offers 90 email verifications. 

Verification methods

Not all platforms open up about the details of how the verification process is conducted. But you may want to do your research to be sure that the results provided are accurate. However, regardless of the service you choose, it should use SMTP Authentication (aka email ping) for the most accurate results.

Extra tools and features

In 2025, not using tool bundles is a waste of time and effort. Why switch between a dozen tools when you can have them all on a single platform? Fortunately, many email verification services offer complete toolboxes with CRM, email finders, verifiers, senders, and trackers. We’re one of them!

API verification

If you want to incorporate email verification directly into your platform or product, you need an API. This isn’t exactly a must-have for every email verification platform, but it opens up possibilities for email verification in ways you probably haven’t considered before.

Integrations

Email verification is just one of the steps in organizing your email marketing and sales. And it’s likely that most of your sales and marketing efforts are managed through CRMs and other management platforms. To make the synchronization between platforms easy, it’s important to choose an email checker that is part of the CRM or can be integrated with CRMs like Pipedrive and platforms like Zapier to sync with other automation platforms, calendars, etc.

Support

Working with complex email marketing tools is no walk in the park, and sometimes you will have questions. That’s why support (preferably human) is an important element of every great email verification service. Make sure the tool of your choice offers at least two ways to contact the team if you face any issues or have any questions.

Reviews

And finally, REVIEWS. You can never truly be sure in the tool until you check real reviews. We recommend looking at platforms like G2 and Capterra that offer instant comparison to competitors, as well as deep insights from real users.

FAQ

  • How often should I test email addresses for validity?

    If you don’t do email list verification regularly, you’ll have the risk of sending emails to contacts that no longer exist. This will increase your bounce rate and negatively affect your sender reputation and email deliverability. So, you need to validate email address lists periodically, especially as soon you notice any issues with email deliverability and sender reputation. A good rule of thumb is to check emails once in two months, but not later than 90 days after your previous email check.
  • How does an email validator work?

    Every email validator, also known as an email verifier, email address checker, or email tester, performs email verification according to the developers’ algorithms. For example, Snov.io Email Verifier goes through 7 steps of email verification for maximum accuracy:
    • syntax check
    • gibberish check
    • domain existence check
    • MX record check
    • catch-all domain check
    • SMTP authentication (email address ping)
    • free email check
