wp_mail wordpress html with style not aplying in WordPress

I’m trying to send mail from my wordpress plugin but when I retrieve it, it has not styles or images.

I’m doing this way:

<?php
$headers = array(
    "From: Enara <no-reply@enara.es>",
    "MIME-Version: 1.0",
    "Content-type: text/html; charset=UTF-8'"
);
$message = "<html>
    <head>
        <meta http-equiv='Content-Type' content='text/html; charset=utf-8' />
    </head>
    <body>
        <div style='background-color: #16a085;'>
            <table>
                <tr><td colspan='2'><img style='margin-botton: 20px;' src='http://enara.litrodeenergia.com/wp-content/uploads/2015/12/enara-white.png' /></td></tr>
                <tr><td colspan='2'>DATOS DE CLIENTE</td></tr>
                <tr><td colspan='2'>$particular</td></tr>
                <tr>
                    <td>Nombre:</td>
                    <td>$nombre<br></td>
                </tr>
                <tr>
                    <td>Apellidos:</td>
                    <td>$apellidos</td>
                </tr>
                <tr>
                    <td>Nif:</td>
                    <td>$nif</td>
                </tr>
                <tr>
                    <td>Tel&eacute;fono:</td>
                    <td>$telefono</td>
                </tr>
            </table>
        </div>
    </body>
</html>";

$result = new stdClass();
$result->mailOk = wp_mail($to, $subject, $message, $headers);

I tried a style code in my head, delete the html/head/body blocks (only send the div html code), changed the content-type to iso, and made the wp filter wp_mail_content_type ‘text/html’.

The image don’t work also.

If I debug the recieved email with devtools, I see:

<div style="background-color:#16a085">
<table>
<tbody>
    <tr>
        <td colspan="2"><img src="http://enara.litrodeenergia.com/wp-content/uploads/2015/12/enara-white.png" style=""></td>
    </tr>
    <tr>
        <td colspan="2">DATOS DE CLIENTE</td>
    </tr>
    <tr>
        <td colspan="2">Usuario particular</td>
    </tr>
    <tr>
        <td>Nombre:</td>
        <td>afsd<br>
    </td>
    </tr>
    <tr>
        <td>Apellidos:</td>
        <td></td>
    </tr>
    <tr>
        <td>Nif:</td>
        <td></td>
    </tr>
    <tr>
        <td>Teléfono:</td>
        <td></td>
    </tr>
</tbody>
</table>

And the email headers:

It could be better if you put the code how did you use wp_mail_content_type

You should filter content type before call wp_mail() For example:
```
add_filter('wp_mail_content_type', function( $content_type ) {
            return 'text/html';
});

wp_mail( 'me@example.net', 'The subject', '<div>The message</div>' );
```

Try adding
```
add_filter('wp_mail_content_type',create_function('', 'return "text/html"; '));
```
Seems by default wp_mail() returns text/plain content.

You can use WordPress’s wp_mail() function to send emails from your WordPress site. However, the default content type is ‘text/plain’ which does not allow using HTML. If you want to send HTML emails then you will need to set the content type of the email to “text/html” by using the ‘wp_mail_content_type’ filter.

Edit

Issue seems to be related to mail client rendering of HTML content.
