How Does Email Verification Work?

The email verification is carried out in a three-step process that occurs in fractions of a second. These steps include:

  • Checking Email Syntax and Formatting
  • Server or Domain Confirmation
  • Mailbox Validation

Checking Email Syntax and Formatting

The first email verification step is to check the email syntax. Email syntax is the correct order that an email address ought to be created. The verification service examines the email addresses against the syntax of other recognized email service providers. For instance, a valid Yahoo email address won’t begin with a number. If it does, then it’s a sign that the address may be fake.

After the email syntax, the service checks email formatting. There are intricate rules that show the admissible usernames for email addresses when it comes to email formatting. The formatting process takes several and different orders, so it can not be a manual process. Therefore, it requires an email verification engine to check within seconds. These checks point out to the fact that an email address shouldn’t contain any special characters.

Another process check example is the mandatory “@” symbol that needs to be present in all email addresses. Let’s say you have a custom writing service review website called Online Writers Rating on your mailing list. Can you spot which of the email addresses the verification check will pick up as invalid?

Server or Domain Confirmation

The server of domain confirmation is the next step for email verification. The email verification service check shows the DNS records for the email address domain name. If you have an email address “sales@lol.com,” the domain name is “lol.com.” Thus the verification service analyzes the mail exchanger (MX), ensuring that the address is valid and can receive emails. Additionally, a full email box will lead to high bounce rates. As a result, the server or domain confirmation helps to take out the fake addresses. But because the services aren’t able to tell between a full box or phony email address, it leads to the same decline in sender reputation.

Mailbox Validation

Once the verification service can check the first two steps, it moves to the mailbox validation. In this step, the service validates the mailbox. It entails trying to reach the Simple Mail Transfer Protocol (SMTP) server. (The SMTP is a communication protocol for electronic mail transmission) Then it tries to understand if the particular mailbox exists and can receive emails.

In this step, the verification service sends the email address with an EHLO message. Then it will wait for a response from the email server. If there is a server response, it means that the email address exists and can receive emails.

Generally, the best email verification services can carry out these steps without sending a single mail. The process mechanism behind it allows it to verify your emailing list in no time. But this may also depend on how large or small your email contact list is. The email server age, workload, and modern anti-spam systems can sometimes slow the processes down.

Besides these checks, verification services also check for duplicate email addresses, role accounts, spam traps, and temporary email addresses. Such assessments can be done based on your business email marketing needs. There is also the real-time verification that validates each email address at the time of signup. It is carried out by integrating an email verification API with your system to collect customer data. Therefore, the data that is coming into your system is healthy. Alternatively, there is a double opt-in procedure that can be done right after signup. But this process might rob your subscribers off in the wrong way when you send them confirmation emails.
