    use Symfony\Component\Mime\Email; $email = (new Email()) ->from('fabien@symfony.com') ->to('fabien@sensiolabs.com') ->subject('Some subject')

    ->text('Some text message') ->html('<b>Some HTML message</b>') ->attach('doc.txt') ; The basics
  19. 28.

    $email = (new Email()) ->from('fabien@symfony.com') ->to(new Address('fabien@sensiolabs.com')) ->addTo(new NamedAddress('fabien@sensiolabs.com', 'Fabien'))

    ->addCc('thomas@symfony.com', 'lucas@symfony.com') ->addCc(...['thomas@symfony.com', 'lucas@symfony.com']) ->subject('Some subject') ->text('Some text') ; from, to, cc, bcc
  20. 29.

    $email = (new Email()) ->from('fabien@symfony.com') ->to('fabien@sensiolabs.com') ->subject('Some subject') ->text('Some text

    message') ->html('<b>Some HTML message</b>') ; echo strlen(serialize($email)); Email is a data object Only 2k vs 16k for Swiftmailer
  21. 31.

    $email = (new Email()) ->text('Some text message') ->html('<b>Some HTML message</b>')

    ; $email = (new \Swift_Message()) ->setBody('Some text message') ->addPart('<b>Some HTML message</b>', 'text/html') ; A better data object model 16k serialized 38 objects complex serialization "fixed" headers 2k serialized 7 objects simple serialization "dynamic" headers
  22. 33.

    $email = (new Email()) ->from('fabien@symfony.com') ->to('fabien@sensiolabs.com') ->subject('Some subject') ->text(fopen('email.txt', 'r'))

    ->html(fopen('email.html', 'r')) ; echo $email->toString(); foreach ($email->toIterable() as $chunk) { echo $chunk; } String or resources, your choice
  23. 34.

    // Email extends Message use Symfony\Component\Mime\Message; use Symfony\Component\Mime\Part\TextPart; use Symfony\Component\Mime\Header\Headers;

    $body = new TextPart('Some content'); $headers = (new Headers()) ->addMailboxListHeader('From', ['fabien@symfony.com']) ->addMailboxListHeader('To', ['fabien@sensiolabs.com']) ->AddTextHeader('Subject', 'Some subject') ; $email = new Message($headers, $body); And you get full control!
  24. 35.

    $txt = new TextPart('Some content'); $html = new TextPart('<b>Some content</b>',

    'html'); $body = new AlternativePart($txt, $html); $email = new Message($headers, $body); Get creative
  25. 36.

    A "complete" email multipart/mixed | |------------> multipart/related | | |

    |------------> multipart/alternative | | | | | ------------> text/plain | | | | | ------------> text/html | | | ------------> image/png | ------------> application/pdf ->text() ->html() ->embed() ->attach()
  26. 39.

    $email = (new Email()) ->from('fabien@symfony.com') ->to('fabien@sensiolabs.com') ->subject('Some subject') ->text('Some text')

    ->html('<b>The new logo: <img src="cid:logo.jpg"></b>') ->embedFromPath('logo-small.jpg', 'logo.jpg') ; Embeds
  27. 40.

    // Email extends Message extends RawMessage use Symfony\Component\Mime\RawMessage; $message =

    new RawMessage($email->toString()); $message->toString(); Go raw! Serialize an email as a string instead of a PHP object
  28. 41.

    Creating Emails with Twig Twig is perfect for emails aka,

    Twig is not dead and still very useful :)
