Best 10 Email Checker and Verification Tools in 2023

If you are running an online business, chances are you’ve been intensively using an email checker and email verification tool in your email marketing efforts for quite some time.

Email marketing has been one of the most vibrant and effective communication tools between business owners and consumers. At the end of 2008, 44% of consumers admitted that email marketing messages sent to their personal and business email addresses had become one of the driving factors of their online purchases. Recent studies report that more than 2.5 billion people worldwide still use email, which is anticipated to grow to 2.8. billion people in the next few years. 

Email is such an extensive discipline. The creation of a powerful tool called email had the same life-altering communication power as telephones when they were first created. To date, email newsletters and sales pitches are still one of the most promising and cost-effective digital marketing approaches to generate more income for your business online. Harnessing emails as a marketing channel is critical to every business and industry.

A robust email list for your business can provide a high conversion rate and return on investment (ROI) income. Managing a contact list is becoming more demanding as the email lists grow. Email verification is essential for every email marketing effort as it ensures that every email message is sent to each email address with precision and accuracy.

Emails sent to invalid or fake email addresses, whether a business or personal address, will get bounced back, affecting the whole deliverability score of your email marketing campaigns. To ensure that your emails are adequately sent to their respective recipients, an email checker or email verification tool can reduce the email bounce rate and increase the deliverability rate, especially when sending bulk email newsletters to your email list.

What is an Email Checker?

An email checker is a software used to check the validity of email addresses to ensure that email campaigns are sent to legitimate email addresses. Email checker allows users to upload email lists to its platform to verify the list of emails in several logical ways. An Email verification tool can accurately identify the email address and domain structure and check a mailbox against an internet service provider to see if it exists. As a result, users can download the final email results of the email verification process and obtain the up to date, clean, and verified email lists.

In addition, an email checker tool can clean up fake and inactive users from your mailing lists, ensuring that your email marketing letters will be received by real and active users and preventing them from going under the spam folder. Marketing teams often use an email checker to improve email campaign performance, deliverability rate, and user engagement. This software is regularly integrated into a popular email and customer support software to maximize the number of emails that get read from the mass or bulk email marketing sending process to their customer base.

An email checker is an excellent tool for saving money and avoiding costly mistakes from sending emails to inactive and fake email addresses, as invalid email addresses produce a high bounce rate and reduces the deliverability score. An email verification tool can also detect if the email is a disposal or temporary email address, which is being used mostly by scammers and hackers. Furthermore, this tool can be used to check or verify the email address entered and submitted by users in any web forms to check email lists for invalid or bounced addresses and validate email addresses before sending emails.
