Swift Mailer


Loads the Swift Mailer library into WordPress and nothing more. See http://swiftmailer.org for more information.

This plugin was created to provide a reliable way to update the core Swift Mailer library across multiple WordPress installs. The plugin loads only the core library so any mail functions will have to be written.

Feedback welcomed! For feature requests or questions, create a thread on the support tab (https://wordpress.org/support/plugin/swift-mailer) or email hello [at] turnonsocial [dot] com


  • Sample code for application


Upload and activate. You can then use the Swift Mailer library within your code – swift_required.php is automatically included.

Sample connect and send code (full documentation available at: http://swiftmailer.org/docs/sending.html )
// Create the Transport
$transport = Swift_SmtpTransport::newInstance(‘smtp.example.org’, 25)
->setUsername(‘your username’)
->setPassword(‘your password’)

// Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);

// Create a message
$message = Swift_Message::newInstance('Wonderful Subject')
  ->setFrom(array('john@doe.com' => 'John Doe'))
  ->setTo(array('receiver@domain.org', 'other@domain.org' => 'A name'))
  ->setBody('Here is the message itself')

// Send the message
$result = $mailer->send($message);


How do I use this plugin?

Upon activation, the Swift Mailer library is available to you throughout your codebase. Simply create a transport, create a message and send.

Do you have sample code for sending an email?

See the fantastic Swift Mailer documentation http://swiftmailer.org/docs/sending.html

Where do the library files come from?

All lib files are pulled directly from the official Swift Mailer github repo at https://github.com/swiftmailer/swiftmailer
