An email address validator is a tool that verifies whether an email address is
valid or not. It checks the syntax of the email address, the domain name, and
the mailbox existence. By using an email address validator, you can ensure
that your emails will be delivered to valid email addresses only.

How to Check if an Email Address is Valid

There are several ways to check if an email address is valid. Here are some of
the most common methods:

  • Send a Test Email: You can send a test email to the email address and see if it bounces back. If it does, the email address is most likely invalid.
  • Use an Email Verification Service: There are many email verification services available that can check if an email address is valid. These services typically check the syntax of the email address, the domain name, and the mailbox existence. Some popular email verification services include Email Checker, Clearout, and Wiza.
  • Check the Syntax of the Email Address: You can check the syntax of the email address by using a regular expression. A regular expression is a pattern that matches a string of text. Here is an example of a regular expression that checks the syntax of an email address: /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}$/i
  • Check the Domain Name: You can check the domain name of the email address by using a DNS lookup. A DNS lookup is a process that translates a domain name into an IP address. If the DNS lookup fails, the domain name is most likely invalid.
  • Check the Mailbox Existence: You can check the mailbox existence of the email address by using SMTP verification. SMTP verification is a process that sends a message to the email server and checks if the mailbox exists. If the mailbox does not exist, the email address is most likely invalid.

Conclusion

Checking if an email address is valid is an important step in improving your
email deliverability. By using an email address validator, you can ensure that
your emails will be delivered to valid email addresses only. We hope that this
guide has provided you with the information you need to check if an email
