Without an email validator, it’s hard to maintain the email list hygiene, putting your company’s marketing efforts at risk.

Let’s look a little closer at what an email validator is and check out the top 10 validation tools.

What is an Email Validator?

An email validator is an application that checks your email list to discover any issues like spam traps, invalid addresses, typos, syntax errors, and more. You can activate this software either as the user enters information or run a list of addresses through it post factum.

The app uses complex algorithms to ensure the validity of your address list and checks it against all the available databases. The program pings the email service provider to figure out if recipients can receive messages without disturbing them.

The benefits of using an email validator for your company include:

  • Good sender’s score – when your emails don’t reach their destination and bounce, your sender’s reputation goes down, making it harder to achieve email marketing goals.
  • Client retention – if you send emails to wrong addresses, you don’t reach clients you wanted to interact with. This can hinder your retention efforts. With 80% of your future earnings coming from 20% of your existing customers, retention is worth extra attention.
  • Lower costs – when you send emails to wrong addresses, you are paying extra money for your marketing efforts and wasting manpower.
  • Better marketing campaign – by cleaning your email list, you are giving your marketing campaign a better chance of succeeding. Sending emails to invalid addresses gives you the wrong idea about your campaign’s effect.
  • Saved time – you can save hours on checking email lists manually. A validator can do it in a few seconds. Real-time email validators can make sure you only add valid email addresses to your list.

10 Top Email Validators on the Market

When choosing the best email validator for your company, you should pay attention to the following factors:

  • Bulk and real-time validation (API) – can the validator check email addresses in real-time, clean your email lists in bulk, or both?
  • Costs – many email validators come with free trials or demos. They have different pricing plans depending on the software functionality.
  • Online functionality – can you check your email lists online or do you need to download the software?
  • Reviews – how happy are previous users with the software?
  • Accuracy – an email validator should guarantee certain results. Usually, its between 95% and 100%. If the provider doesn’t give any guarantees, consider other options.
  • Security – since the validator works with sensitive information, such as email addresses, it should offer top-notch security,
