Sending html and css mails to gmail with Swift Mailer

Question

I have some basic html and some css but for some reason gmail puts 3D infornt the 'text/css'

Code sample

$message = "
            <style type='text/css'>
              #main {border:1px solid red;}
            </style>

              <div id='main'>some text</div>
";

But when I view the original send to the gmail

<style type=3D'text/css'>

and maybe thats why the mail is not styled. I am using the swift mailer

// also in html

<div id=3D'main'>

// swift mailer

    $type = $message->getHeaders()->get('Content-Type');
    $type->setValue('text/html');
    $type->setParameter('charset', 'utf-8');

Answer 1

From what I know gmail doesnt support style tag in head or in body. I use style attributes for elements when sending email.

yes this is true but also you need further lines to make every thing work, check my answer – Raoul

to let swift mailer send message in HTML format, even for gmail , because swift mailer escape html tags to its represented characters , so you need to write these lines this way:

$message = (new Swift_Message('Message Subject HERE '))
        ->setFrom(array('sender email' => 'Sender Name')) // can be $_POST['email'] etc...
        ->setTo(array('reciever email' => 'Receiver Name')) // your email / multiple supported.
        ->setEncoder( new Swift_Mime_ContentEncoder_PlainContentEncoder('8bit'))
        ->setBody($template, "text/html");

after that every thing should work fine the trick here is to till swift mailer to use Swift mailler MimeType class and point to the correct encoding . you can check here for more information link here

Swift Mailer is trying to escape " to \". You have to use setEncoder() before setBody():

$message->setEncoder(Swift_Encoding::get8BitEncoding());
$message->setBody($body, "text/html");

This solution does not work for me. I added $message->setEncoder(Swift_Encoding::get8BitEncoding()); and when I print_r the message after sending from on my server, the HTML part is shown as Content-Transfer-Encoding: 8bit and the equal signs appear as desired (i.e., just =). However, when receiving this message, the HTML part has been changed to Content-Transfer-Encoding: quoted-printable and the equal signs show as =3D. Using Swiftmail version Swift-5.4.3. Tried multiple receiving hosts and multiple receiving mail clients, all with the same result. – Phonology

As mentioned, the $message->setEncoder(Swift_Encoding::get8BitEncoding()); modification did not fix the issue for me. However, $message->setEncoder(Swift_Encoding::getBase64Encoding()); encodes the HTML part as base64 data and this comes through untouched on the other end. This was particularly important to me as not only is the HTML now rendering properly, but I am also signing my messages with an S/MIME signature and the received modified message caused the signature to be invalid. Now, the signature remains valid as the message is unmodified on the receiving end. – Phonology

static calling did not work and even it is not in current version 6.1 documentation, use normal new keyword instantiation instead – Raoul
