What is Email Verification?

Email verification ensures whether the recipient's mailbox accepts emails and is active. It also identifies different email address discrepancies and possible spam traps before it gets flagged by the ESPs (Email Service Providers) or ISPs (Internet Service 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 the behavioral factor 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.

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.

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.

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 automatically becomes invalid, which can cause your email messages to bounce.

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.

When the domain is dead, it's a familiar and technical reason for the email to be verified.

If you find any website unreachable, then 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 determining how to verify email ids. The simplest way is to use an email verification and validation tool. These tools come with a number of important benefits that can help you to improve the performance of your email campaigns.

Benefits of Email Verification Services

The major benefits of using an email verification service are as follows.

Lowers bounce rate

Prevent bounces and preserve your sender reputation. An email verification tool will remove non-existing email addresses, misspelled email addresses thereby lowering bounce rate and protecting your IP reputation.

Scrubs your email database

Enhance your email list with an email scrub. By scrubbing your list, you will be able to collect valuable data about your leads and segment the list based on the data. This will help improve your overall conversion rates.

Analyzes your email headers

Email verification tools will analyze your email headers to ensure your mail server is set up and configured correctly, all with the goal of making sure that your emails reach their recipients.

Monitors your IP and domain

It's essential to monitor your IP and domain reputation and be notified when they are listed on a blacklist. You'll be provided alerts should your IP or domain show up on a list.

Now to choose a good email verification and validation tool you need to understand the basics of email verification and what are the different features you should look for in a tool. Let's start with understanding how email verification works.

How is Email Verification done?

Though many of us use email verifying tools, most of us don't clearly understand how email verification works. Below are a few steps that explain how email verifiers work and the process behind them.

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.

What should you look for in a good email verification and validation tool?

Now that you understand the basics of how email verification works, you can start looking out for a verification and email validation tool that uses these processes to perform testing. As you sift through various tools, here is the list of features that you need to look at before making your final choice.

Online tool

Make sure that it is an online email verification tool that works as SaaS (Software-as-a-Service). Online tools don't need any computer resources as they are easily accessible anywhere and anytime from any device. You also don't use your IP for the verification process; instead, it uses the service's IPs which work way better.

Scalability

The email verifier you choose should be capable of verifying both single email addresses and extensive email lists. Bigger email lists take time in some cases but mostly done instantly.

Personal and corporate emails

You need to ensure whether the email verifier can verify private and corporate email addresses.

Different verification mechanism

The email verifier you choose should verify multiple aspects by running other validation mechanisms like email server ping, domain check, and syntax check.

All-in-one/Connectivity/Integrations

Ensure that your verifier integrates or connects with different tools like email list management tools, email sending tools, email generation tools, and more.
