What is email verification?
Email verification ensures whether the recipient's mailbox is active and accepts emails. It also identifies different email address discrepancies and possible spam traps before it gets flagged by Internet Service Providers (ISPs) or mailbox providers, which can cause severe damage to your reputation.
In other words, email verification enhances deliverability by cleaning up your emails and helps deliver messages to your target audience.
Why is it essential to use email verification tools?
There are different reasons why an email address may turn invalid or stop working. Sometimes it may be due to behavioral factors like a person changing their email address, and sometimes it is because of certain technical glitches.
Below are a few reasons why email addresses might become invalid, and hence verifying your email lists before sending out an email campaign becomes essential.
1. When the recipient changes their email service/provider
Let's say a person uses a local email service provider, and then they switch to Gmail/Hotmail. Your emails will not be delivered to the recipient in these cases, though the old one may still be active.
2. When the recipient changes their email ID within the same email service provider
If a person uses the same email service provider but switches to a new email address, your emails will not deliver and bounce back immediately.
3. When the recipient switches positions within a company
Every employee will have a different email address based on their designation. C-level employees, mid-level, and junior cadre employees have other email address formats. When a person gets promoted from a junior position to a mid-level, their email address becomes invalid, which can cause your email messages to bounce.
4. When the recipient changes jobs
Many decision-makers and specialists often change jobs every few years, and in this case, emails get redirected to another person or become unreachable when a person leaves the company.
To prevent this kind of situation, you can set up email autoresponders. Learn more about them here - A Comprehensive Guide to Understanding Email Autoresponder
5. When the domain is dead, it's a familiar and technical reason to verify the email.
If you find any website unreachable, it indicates that the mail server is down or the domain is dead. In this case, you can't deliver the message to your recipient. When the public email provider is down or dead: There is no chance for the email message to reach the recipient if the server is down or when the email provider is out of business. Sometimes online email providers experience technical server problems or even shut their businesses.
Now that you are clear about the importance of verifying emails and the working mechanism, the next step is to verify email ids. The simplest way is to use an email verification and validation tool. These tools come with many benefits that can help you improve your email campaigns' performance.

How is email verification done?
Though many of us use email verifying tools, most don't understand how email verification works. Below are a few steps that explain how email verifiers work and their process.
• Syntax check
It helps ensure whether the email address is correct, checks spelling, commas, spaces, special characters, and whether the domain extensions are in the right place.
• Domain check
It checks whether the domain name used in the email address exists and is registered and whether it is working correctly on its hosted domain.
• Email ping
Email Ping is the technical process, which pings an EHLO message to the exact email address and then waits for the server's response. If there is a response, it indicates that the email address is correct, exists, and the server is active.
