SendGrid 电子邮件模板样式不适用

Question

我正在使用 SendGrid PHP API 发送时事通讯，但是当我使用模板 ID 时，发送的邮件不包含 CSS 和图像。

这是我的代码：

<?php
require("sendgrid-php/sendgrid-php.php");

$from = new SendGrid\Email(null, "contact@projet.com");
$subject = "Hello World from the SendGrid PHP Library!";
$to = new SendGrid\Email(null, "me@icloud.com");
$content = new SendGrid\Content("text/plain", "hello");
$mail = new SendGrid\Mail($from, $subject, $to, $content);
$mail->setTemplateId("727274bc-XXXX-XXXX-XXXX-83a2b53597e5");

$apiKey = 'SG.XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
$sg = new \SendGrid($apiKey);

$response = $sg->client->mail()->send()->post($mail);
echo $response->statusCode();
echo $response->headers();
echo $response->body();

?>

希望有人能帮助我 谢谢

解决了！只是改变 $content = new SendGrid\Content("text/plain", "hello"); 到 $content = new SendGrid\Content("text/html", "hello");
