validation in Golang.

What is Email Validation?


Email validation is the process of verifying whether an email address is valid
or not. This is important because invalid email addresses can cause delivery
failures and other issues.

Why is Email Validation Important?

There are several reasons why email validation is important:

  • Delivery failures: Invalid email addresses can result in delivery failures, which can be frustrating for both the sender and the recipient.
  • Spam complaints: Invalid email addresses can also result in spam complaints, which can harm your reputation as a sender.
  • Data accuracy: Validating email addresses helps ensure that your data is accurate and up-to-date.

How Does Email Validation Work?

Email validation typically involves checking the syntax, domain, and mailbox
of an email address. This can be done using regular expressions, DNS lookups,
and SMTP connections.

Validating Emails in Golang

Golang provides several packages that can be used to validate email addresses.
Some of the most popular packages include:

  • CheckMail: A package that uses regular expressions to validate email addresses.
  • EmailVerifier: A package that uses DNS lookups and SMTP connections to validate email addresses.
  • Go-Email-Validator: A package that provides a modular approach to email validation.

Each package has its own strengths and weaknesses, so it's important to choose
the package that best fits your needs.


Email validation is an important aspect of email communication. Using the
right tools and techniques can help ensure that your emails are delivered
successfully and that your data is accurate.
