What is the validation email?

Email Validation is a technique of verifying if email addresses are accurate and deliverable. Also, it confirms if an email address has a reliable domain, for instance, Gmail or Yahoo. There could be three types of email addresses:

Valid: Address exists, and this mail-sending process will be completed to the mailbox level.
Risky: The emails exist, although there is a risk that this address could result in a bounce.  
Invalid: There are syntax errors, DNS errors or mailbox errors.

Email validation can be done with different programming languages


Validation in PHP means to check the input submitted by the user. There are two types of validation available in PHP:

  • Client-Side − Validation is performed on the client device web browsers.
  • Server Side − The data has sent to a server and perform validation checks in the server device.


Using jQuery, you can add code to the website by creating a regular expression, which checks for emails such as Gmail, Yahoo, etc. before submitting the form to the server. Also,t regular expression can be modified to reject any domain specified.


An email is a string that are separated into two parts by the “@” symbol. To get a valid email id in Javascript you need to use a regular expression: /^w+([.-]?w+)*@w+([.-]?w+)*(.w{2,3})+$/.


Angular presents several ways of validating email addresses mentioned below:

  • Built-in validation: It comes with some built-in email validators you can use to ensure user-provided emails’ accuracy.
  • Pattern validation: It enables you to specify a regular expression (regex) Angular email addresses validation pattern that should match the user-provided value.
  • Custom validation: You can create your custom email validators.


One of the HTML 5 values to the type attribute is email. Using this attribute of the field instead of the regular text field, the browser uses a regular expression to check that the people have, in fact, typed in an email address.

Does this means that the user cannot type in a fake email address? Not really. But you don’t have to worry that users type in a comma instead of a period. No matter what the user is going to submit, it is going to look like an email address.
