SendGrid電子郵件模板樣式不應用

Question

我使用SendGrid PHP API發送簡報，但是當我使用模板ID時，發送的郵件不包含CSS &圖像。

這裏是我的代碼：

<?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(); 

?> 

希望有人能幫助我 感謝

解決了！只需將 $content = new SendGrid\Content("text/plain", "hello");改爲 $content = new SendGrid\Content("text/html", "hello");
