The 11 Best Email Verification Tools for 2023

Experienced email marketers know that it’s not about sending plenty of nice emails to mark the job done. It’s rather about bringing revenue by ensuring emails get delivered in the inbox and out of the spam folder. 

To ensure their emails are received, marketers and sales teams use email verification software. The goal is to avoid email “bounces”, essentially when an email address either doesn’t exist or no longer exists. When this happens, the email bounces and email service providers use this as a signal to understand your email reputation.

If you get too many bounces, for email providers it could be a sign you’re spamming by emailing contacts in bulk without a prior relationship or due diligence. When this happens, these may start flagging your emails as spam or flagging your emails as commercial messages in the promotional inbox.

Email validation can reduce the email bounce rate by 90% by checking if the email address you want to contact actually exists and works.

With the right email verifying tool, it is possible to significantly reduce your cold outreach and email newsletter bounce rates, protecting your email sender reputation and ensuring emails get received and read.

How to Choose the Right Email Verification Software 

A good validation service should be able to detect invalid, undeliverable, and spam email addresses with the highest accuracy rate. SMTP authentication, domain authentication, catch-all servers, and correct syntax should all be checked.

You can also consider other features while choosing an email verification system.

✅ A good email verifying tool should allow bulk email checking and downloading of the results to your device as well as it should provide an option for uploading your mailing list. 

✅ Fast performance. A good tool should provide the check results without delays and, the information provided should be real-time.
