  3. use Symfony\Component\Mime\Email; $email = (new Email()) ->from('[email protected]') ->to('[email protected]') ->subject('Some subject')

    ->text('Some text message') ->html('<b>Some HTML message</b>') ->attach('doc.txt') ; The basics
  4. $email = (new Email()) ->from('[email protected]') ->to('[email protected]') ->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
  5. $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
  6. $email = (new Email()) ->from('[email protected]') ->to('[email protected]') ->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
  7. // 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', ['[email protected]']) ->addMailboxListHeader('To', ['[email protected]']) ->AddTextHeader('Subject', 'Some subject') ; $email = new Message($headers, $body); And you get full control!
  8. $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
  9. A "complete" email multipart/mixed | |------------> multipart/related | | |

    |------------> multipart/alternative | | | | | ------------> text/plain | | | | | ------------> text/html | | | ------------> image/png | ------------> application/pdf ->text() ->html() ->embed() ->attach()
  10. $email = (new Email()) ->from('[email protected]') ->to('[email protected]') ->subject('Some subject') ->text('Some text')

    ->html('<b>The new logo: <img src="cid:logo.jpg"></b>') ->embedFromPath('logo-small.jpg', 'logo.jpg') ; Embeds
  11. // 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
  12. Creating Emails with Twig Twig is perfect for emails aka,

    Twig is not dead and still very useful :)
  13. use Symfony\Bridge\Twig\Mime\Renderer; use Symfony\Bridge\Twig\Mime\TemplatedEmail; use Twig\Environment; use Twig\Loader\FilesystemLoader; use Symfony\Component\Mime\NamedAddress;
