Cross-language email validation. Backed by a database of 1987 throwable email providers.

• Validate the format of your email (uses validator.js email regex underneath and FILTER_VALIDATE_EMAIL for PHP)
• Validate if the email is not a temporary mail (yopmail-like..., add your own dataset to list.json)

This will be very helpful when you have to contact your users and you want to avoid errors causing lack of communication or want to block "spamboxes".

Mailchecker public API has been normalized, here are the changes:

• NodeJS/JavaScript: MailChecker(email) -> MailChecker.isValid(email)
• PHP: MailChecker($email) -> MailChecker::isValid($email)
• Python

import MailChecker
m = MailChecker.MailChecker()
if not m.is_valid('[email protected]'):
  # ...

became:

import MailChecker
if not MailChecker.is_valid('[email protected]'):
  # ...

MailChecker currently supports:

• NodeJS (CommonJS)
• JavaScript (Client-Side)
• PHP
• Python
• Ruby
• Elixir
• Clojure
• Easily add support for your own language with MailChecker template system and send us a pull-request!

var MailChecker = require('mailchecker');

if(!MailChecker.isValid('[email protected]')){
  console.error('O RLY !');
  process.exit(1);
}

if(!MailChecker.isValid('myemail.com')){
  console.error('O RLY !');
  process.exit(1);
}

<script type="text/javascript" src="MailChecker/platform/javascript/MailChecker.js"></script>
<script type="text/javascript">
if(!MailChecker.isValid('[email protected]')){
  console.error('O RLY !');
}

if(!MailChecker.isValid('myemail.com')){
  console.error('O RLY !');
}
</script>

include __DIR__."/MailChecker/platform/php/MailChecker.php";

if(!MailChecker::isValid('[email protected]')){
  die('O RLY !');
}

if(!MailChecker::isValid('myemail.com')){
  die('O RLY !');
}

Code.require_file("mail_checker.ex", "mailchecker/platform/elixir/")

unless MailChecker.valid?("[email protected]") do
  raise "O RLY !"
end

unless MailChecker.valid?("myemail.com") do
  raise "O RLY !"
end

# no package yet; just drop in MailChecker.py where you want to use it.
import MailChecker

if not MailChecker.is_valid('[email protected]'):
    print "O RLY !"

require 'mail_checker'

unless MailChecker('[email protected]')
  fail('O RLY!')
end

unless MailChecker.valid?('[email protected]')
  fail('O RLY!')
end

; no package yet; just drop in mailchecker.clj where you want to use it.
(load-file "platform/clojure/mailchecker.clj")

(if (not (mailchecker/valid? "[email protected]"))
  (throw (Throwable. "O RLY!")))

(if (not (mailchecker/valid? "myemail.com"))
  (throw (Throwable. "O RLY!")))
