Best Email Validation Service: Top 10 Picks For 2022 (2022)

How Email Address Validation Works

Email address validation identifies invalid addresses that can increase your bounce rate. It can also identify spam traps that hurt your sender reputation. When you validate your mailing lists, you have a better chance of reaching your target market because your campaigns will be sent to valid and active email addresses.

The quickest and easiest way to validate email addresses is to use a validation service. These services automate the verification process by performing a number of checks automatically. Most services verify the validity of an address by looking at the address syntax and the DNS entries of the address. These services may also search your mailing list for role-based and disposable addresses, look for spam traps, and determine if an IP address or domain name has been found in the body of spam email messages.

Types of Email Validation

There are several ways to validate email addresses. When evaluating an email validation service, look at which of these options is best for your mailing lists and choose the service that offers the type of validation that meets your needs.

  • Syntax check: A syntax check looks at the email address and determines whether it is in the correct format. This is the simplest type of validation check. Still, it has limitations because it identifies addresses with special characters as invalid. A syntax check also doesn’t look for inactive or non-existent domains and user accounts.
  • Double opt-in: This type of validation sends a confirmation email to the person who signs up for a newsletter or enters their address in a website form. When the person receives the confirmation email, they click a link in the message to confirm their email address and that they want to be included in future mailings. The downside is that if an incorrect address is entered, that person won’t receive the confirmation email.
  • Real-time validation: Many email validation services provide an API that checks an email address for the correct syntax when the email address is entered on a website. Most real-time validation checks only look for syntax errors. While this method may reject many addresses, it can increase the quality of the email addresses in a mailing list.
  • Bulk or batch cleaning: This type of validation is best for marketing professionals who have many existing email addresses that have never been validated. These mailing lists are usually uploaded to the service as a CSV file, and it may take the service hours or days to check the addresses.

What Is an Email Validation Service?

Your email list is one of the most valuable assets when it comes to digital marketing. You can use it to attract new customers and also to keep existing ones engaged. However, you can’t expect the mailing list to fuel your marketing campaigns effectively unless you take good care of it.

What does it mean to take care of a mailing list? Well, it means proactively removing addresses that have become inactive, addresses with spelling or syntax mistakes, disposable mail addresses, honeypots, and other entries that wouldn’t lead to successful delivery.

While you could do this work manually, it’s more efficient to use an email validation checker and let it take care of everything for you. Here’s a small sample of what the best email validation service providers do:

  • Remove improperly formatted addresses
  • Verify the DNS entries of email addresses
  • Get rid of throwaway/disposable addresses
  • Detect honeypots and bogus email addresses
  • Perform deep-level extended SMTP verifications
  • Flag role-based accounts

Sounds great, right? The good news is that getting started with email list validation is easy—you just need to pick the right service and upload your mailing list. Most services charge based on the number of validations you perform, so you don’t have to worry about blowing your budget if you’re just starting out and your list is relatively small.
