The main email verifier features and validation steps:

Stage 1 — Syntax Check For all email verifier services, this is the key feature, the first step of validation. Syntax check allows you to verify that an email address is correctly spelled, with no spaces, commas, and all of the @s, dots, and domain extensions in the proper places.

Stage 2 - Domain Check The second stage in the email verification procedure is to check the domain. Domain check verifies that the domain name on which the email address is hosted exists is registered and is operational on the hosting domain.

Stage 3 - Email Ping This is the most advanced email verification step. The technical procedure of an email verifier service pinging the precise email address with an EHLO (extended HELO) message and then waiting for the email server's response is known as email ping. The returned server response will validate that the email address is valid and active on the server.

Users can utilize several email verifier services to get all or part of these verification techniques. Email Verifier, for example, employs all of the main techniques, resulting in one of the best validation rates, whereas, a prominent rival, does not even check personal emails housed on Gmail.

Why Should You Verify Emails?

There is a multitude of reasons why an email address may no longer operate or be deemed invalid. Some of the causes are technological, while others are human-related – things change, and anything may happen. Let's look at some of the most typical reasons to double-check your email lists.

Person's Email Provider/Service was Changed This is most likely one of the most prevalent causes. Here's an example: a person utilized their email provider's (local) email service before switching to Gmail, or vice versa. Alternatively, someone could have moved from one popular inbox provider to another. Most crucially, a message sent to the first email address will never be viewed, even if it is still "live."

Person's Email ID was Altered Another typical case is when someone continues to use the same email provider but changes to a separate account with a different email address. Let's assume the email address was at first, and then the individual converted to as a more acceptable email address.

Person Changed his Employment Status Undeliverable messages are quite prevalent, especially in B2B niches, where many specialists and decision-makers change employment every few years. When a person quits a firm, their email becomes inaccessible or is simply redirected to someone else. Even if your message is sent, it will not reach the intended recipient.

These are the few typical reasons that exist. In addition, there are other reasons that include a Person who changed his employment within the same organization, the domain is dead, the email provider went down or it is dead, and more.

Which Emails Should be Verified?

Each and every email address, as well as every email list, should be validated. As you've read through the reasons above, you've realized that any of them might happen at any time. As a result, the more frequently you check your current email lists, the better, and you should always validate new email lists.

Some individuals just check new email lists or email lists created from untrustworthy sources, which is beneficial but does not entirely eliminate the risk. You should constantly double-check fresh email lists, even if they were purchased or created from reputable sources (such as expensive third-party databases and vendors). You should also periodically verify your current email lists (like once a month).
