Email verification is the process of confirming the validity of an email address. It is a must-do task in email marketing and is also known as email list cleaning and validation.

Anyone can make a mistake when writing an email address, and as a result, the email address becomes invalid. Emails sent to invalid email addresses bounce, lowering the deliverability score during email marketing campaigns.

Email bounce rates should be lower in order to achieve a positive ROI on email marketing campaigns. Therefore, the email verification process is used to reduce email bounce rates. The end result will be a higher deliverability rate and protect your email server’s reputation.

In this article, let’s see the 11+ best email verification tools on the market that you can use to remove bad apples from the email list. With a healthy list, your result with email marketing will get significantly better. Let’s get started.

Table of contents:

How does an email verification tool work?

The legitimacy of an email address can be determined using a combination of validation techniques and proprietary algorithms, depending on the internal database. Any invalid addresses will be filtered out at the end of the list validation process, leaving a clean, fully deliverable email list ready for marketing and business needs.

To learn more about the email verification process, you can read How to verify email addresses.

For an email verification tool, it uses an email validation process to separate the bad from the good. Its steps behind the loading screen is something like this:

  1. Remove improperly formatted email addresses by scanning the syntax.

  2. Verify the DNS entries of email addresses and identify invalid ones.

  3. Detects role-based accounts such as [email protected], [email protected], [email protected], [email protected], etc. - which can negatively affect deliverability.

  4. Detects and processes disposable/throwaway email addresses.

  5. Detects BOTs, spam seeds, blacklisted, honeypots, and bogus email addresses.

  6. Check DNSBls and URI DNSBLS to find email addresses with Ips often used for spamming.

  7. Performs deep-level SMTP verification on each email address.

With such a fool-proof email verification process like that, email verification tool is a fantastic way to have a better email list quickly.
