What Is Email Validation? Meet 5 Powerful Alternative Email Validation Tools

What is email validation

Email validation is a process of verifying the accuracy of an email address. It helps to ensure that the email address exists and is able to receive messages. However, what is email validation and its effective methods are of great importance. This process can be done manually, but it is more commonly done through automated means.

It is significant because it helps to ensure that your messages are reaching their intended recipients and are not spoofed. Moreover, it also helps prevent typos from causing problems down the road. There are a few different methods of email validation such as syntax checking, domain validation, SMTP verification, MX record check, and Regex matching.

The different types of email validation

The verification of an email address can be done through several different methods to evaluate its authenticity. Various methods of email validation are discussed as well.

Syntax Checking

This method involves verifying if an email address is in the correct format according to the provided rules. It is an uncomplicated method that could be done in no time.

Domain Validation

The most common method of email validation is called domain validation. Domain validation checks the domain part of an email address to see if it is valid and exists. This method is simple and fast, but it can be fooled by fake domains or domains that are no longer active.

SMTP Verification

Another method of email validation is called SMTP verification. SMTP verification connects to the mail server of the email address to see if it exists. This method is more reliable than domain validation, but it can be slow and may not work with all mail servers.

MX Record Check

The third method of email validation is called MX record check. MX record check looks up the MX records for a domain to see if there is a mail server associated with it. This method is more reliable than domain validation, but it can be slow and may not work with all domains.

Regex Matching

Finally, there is a fourth method of email validation called regex matching. Regex matching uses a regular expression to match an email address against a known pattern. This method can be very accurate, but it can also be slow and may not work with all email addresses.

Pros and cons of email validation

There are a few different methods of email validation, each with its own set of pros and cons.


• The syntax-checking method uses a simple regular expression which is fast and relatively reliable.
• The domain-checking method is more reliable because it involves a test email to see if it bounces back.
• SMTP verification is a less common method but it is more accurate because it connects with the server and if the address doesn’t exist, you should get an error message from the server.
• The MX record check is also more reliable because it works by associating with the mailing server.
• Finally, Regex matching gives you very accurate results as it also uses regular expressions.


• The Syntax checking method can’t catch all errors, and it doesn’t verify that the email address actually exists.
• The domain-checking method can be slower and it may give false positives if the mailbox is full or temporarily disabled.
• The SMTP verification can work slowly and may not work on all servers.
• The MX record check only works on specific domains hence it can give you slow results.
• The Regex matching is email address specific and doesn’t work on all email addresses so it doesn’t provide you fast results.

How to validate an email address?

There are a few simple steps you can take to validate an email address.

First, check the email’s syntax. This can be done by looking for the “@” symbol and a period in the correct order. If these are not present, the email is invalid.

Next, check the domain name. Make sure it is spelled correctly and that there is a period in the correct place.

Finally, check the message delivery system to make sure it is working correctly.

Email validation tools

Email validation tools are like virtual assistants which are used to verify the accuracy and validity of email addresses for you. They can be used to check if an email address is valid, if it exists, and if it is deliverable. Email validation tools can also help to prevent bounced emails and protect against spam.
