10 Top Email Validation Services

Email list hygiene is an integral part of your sales and marketing efforts. Without a clean email list, it’s hard to maintain a good sender’s’ reputation, streamline customer relationships, and take advantage of the impressive email marketing ROI.

To keep your email list in top shape, you need the right tools. One of them is an email validator. Email validators have various functions that include checking your email address list, reviewing new email addresses, correcting typos,  removing spam traps, and many more.

With a wide variety of email validators on the market, it could be tough to choose the right one. Let’s take a closer look at selecting the right service provider and top 10 email validator tools.

How To Choose An Email Validator

When trying to find the right email validation service for your needs, many companies pay special attention to the price. In reality, there are many other factors that should affect your decision.


There are different types of email validation. Not all service providers offer the entire collection. Depending on your company’s needs, you have to review each of these functions to figure out which ones are essential or secondary.

  • Syntax – many people make a mistake when typing their email address. A simple typo turns into a bounced email. Validators with syntax checking option review the format of each address to see if it requires your attention. They also check whether email domains are active or invalid.
  • Confirmation – if you need your clients to sign up for an email list or a service on your website, it’s essential to verify their intentions. Some email validators can automatically send confirmation emails to each address that you add to the list.
  • Real-time validation – when clients enter their email addresses on a website, they often make mistakes. If the address ends up on your email list, it can stay there until the next validation cycle. Some validators offer real-time checks of email addresses. They include checking the syntax and alerting the client about an error.
  • Batch validation – if you have a big email list, it could take a while to check each address with an email validator. Many validators offer batch validation that verifies large mailing lists. Batch validation usually takes longer than single email real-time validation. However, it’s a must-have for large marketing campaigns.
  • Spam traps – spam traps are email addresses that identify your messages as spam. If one of them is on your list, your emails are likely to end up in the spam folders. Some validators can check for spam traps and delete them during the validation process.

Syntax checking is a must-have function of all high-quality validators. The rest can be optional, depending on your business requirements.

Learning curve

Since you already have a number of tools to help with sales and marketing, learning how to use a new one may seem daunting. That’s why it’s imperative to choose an email validation service with a low learning curve.

Many email validators offer free trials. Take advantage of them to figure out which one suits you best.


While not the most important factor, pricing plays a major role in choosing the right email validation service.

Each email validation provider sets its own pricing plan. Some charge per checked email address while others have subscriptions.

The number of addresses on your list is the key to choosing the best price. Compare the available options to see which one is the best for your volume. Keep in mind that your business is likely to grow with time and so will the number of email addresses on the list.
