我正在尝试从我的 WordPress 插件发送邮件，但是当我检索它时，它没有样式或图像。
我正在这样做：
<?php
$headers = array(
"From: Enara <[email protected] /cdn-cgi/l/email-protection>",
"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>$nif</td>
</tr>
<tr>
<td>Teléfono:</td>
<td>$telefono</td>
</tr>
</table>
</div>
</body>
</html>";
$result = new stdClass();
$result->mailOk = wp_mail($to, $subject, $message, $headers);
我在脑海中尝试了样式代码，删除了 html/head/body 块（仅发送 div html 代码），将内容类型更改为iso，并制作了wp过滤器wp_mail_content_type'文本/html'。
图片也不起作用。
如果我使用 devtools 调试收到的电子邮件，我会看到：
<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>
以及电子邮件标题：
