What is email validation, and why is it important?

Email is one of the most popular and successful communication methods, with the vast majority of people checking their inboxes on a regular basis. Worryingly, just 10% of the email addresses obtained are correct; the majority of this inaccurate data is the result of human mistakes. Authentic consumers begin with authentic emails – and the use of email validation is still the most effective method of ensuring the acquisition of high-quality information. The effectiveness of your email marketing rises, as does the effectiveness of your fraud protection, and the capacity to defend your sender reputation increases as a result of the verification of email addresses.

You should always validate your email addresses for three reasons.

Hard bounces should be avoided at all costs.

Hard bounces are most commonly caused by an email address that no longer exists, was created as a fake email address, or was closed by the user.

Reduces the number of spam complaints

According to best practices, you should receive less than five spam complaints about every 5,000 email messages you send out.


If your communications (including transactional emails) are blacklisted, the server will not accept any of your messages from that point forward.

How to maintain the integrity of your email address data and get secured email validation

Your number one rule is to ensure that your data is of high quality.

Cleaning your email address lists on a regular basis with a batch email validation tool can find outdated or erroneous email addresses and delete them from your list before your next marketing campaign. Real-time email address verification allows you to check each newly obtained email address in order to avoid mistakes and bogus accounts from causing further undesired hard bounces in the future.

Examine your database on a frequent basis.

Unengaged subscribers should be reviewed and removed. Non-interested users can cause difficulties; delete people from your mailing list if they have not read any of your emails in the last three months to decrease the possibility of spam complaints and hard bounces.

What is a proper email address format to use?

By incorporating an additional layer of safety into your website, you may increase the success of your efforts and increase your revenue. A warning message will be displayed when the user is first registered, and if his or her email address is provided wrong (either purposefully or inadvertently), the program will display an error message and prompt the user to submit the right information. As a result, only emails with proper email address formats will be sent.

When it comes to email addresses, the usual verification of mailers looks at two components: the mail prefix and the domain.

Email domain

The email domain is shown to the right of the @ sign, and it is case-sensitive. An individual postal service provider has its own set of letters and numbers that distinguishes them from the rest of the world. The maximum length of a domain name is 255 characters. It must adhere to the requirements for hostnames specified in the standard.
