Email verification is a way of ensuring that the messages you send to customers in your mailing list are delivered to them. The process is carried out through an email verifier software that firstly analyzes each email address for typos or possible errors. It then performs a ping test to identify whether the account exists and belongs to a real person.

The benefits of checking your mailing list are many. You can easily guarantee a high campaign delivery rate while focusing on making them more efficient.

Any business that invests in Email Marketing should also invest in a tool that makes the mailing list "cleaner" and up-to-date. But how to choose one?

Currently, marketing managers have the option of choosing between various types of email verifiers. To help you make a decision, we have outlined a review of the main ones below.

Email verifier solutions

Every marketing manager's goal is to turn contacts into sales conversions. But for that to happen, you need to get your messages to reach your leads first.

Email verification programs guarantee this. They have the right resources to separate fake or disposable email addresses from real people's accounts. Their key features include:

1. Syntax checking: checking for errors, such as spaces or invalid characters and whether characters, such as @ and periods are properly typed and in their proper places;

2. Domain verification: verification of the existence of registered domains or a typing error in the domain;

3. Email ping: sending a test to the recipient's email server or host to verify that it is active and in use.

These are the basics of every tool. However, different tools can vary in features that make email verification even easier. This ensures that the efforts invested in marketing campaigns will successfully reach the recipients inbox, giving them an opportunity to become brand customers.

And what is better: the email verifier allows you to evaluate lists with millions of emails, so that no contact in your mailing list is left without validation.

Some of these options also offer a free trial, so you can test them to check whether the service meets your needs. Check out below the 7 best options of email verifiers available on the market!


TheChecker is on top of the best email verifier platforms used by giants such as Netflix, Zumper, weWork, openTable, and thousands of other companies in more than 170 countries.

The program has 99% accuracy in its checks, which is one of the highest rates in the market. It has a Bounce Checker, which analyzes which emails are likely to return to your inbox due to failed sending and also identifies which ones are unsafe to send.

TheChecker detects typos in both the name and domain, domain validity, syntax errors, and performs a risk analysis for malicious recipients.

The solution allows teams with more than one user to access it, so that multiple administrators can share the same account and mailing lists. It shows duplicate email addresses, removes spam filters that might send your email to the spam box, and also checks for "mask" emails, which are used to hide the recipient's real address.

TheChecker also detects role-based addresses, which are unlikely to bring positive results to your campaigns. Also, the software allows you to import lists manually or through integrations, such as Mailchimp, HubSpot, MailerLite, and Campaign Monitor.

The results after verification can be exported in several formats, thus meeting your needs.

Another highlight is that the email verifier accepts several email list formats for verification, making the process simpler, regardless of the operating system or program you use. All with 24x7 support and more than 99% reliability.

When registering, you automatically get 100 credits (to check 100 email addresses) to try the service. The prices vary according to the number of credits. If you want to check 10k emails, the cost is $ 19, and $ 649 for 1M checks.

2. NeverBounce

NeverBounce is a quick email verification tool. It allows you to process lists of 500 to 500,000 email addresses.

However, the email verifier does not provide a more in-depth insight into exactly why an email address was filtered out during the cleanup process. It puts emails into general categories (Valid, Unverifiable, Unknown, Disposable, and Invalid), but does not provide details about each account.

NeverBounce charges $ 50 for checking 10k of emails and $ 2,590 for 1M of checks.
