我正在使用Python / Flask和mandrill smtp在用户分享时发送电子邮件确认。我有一个问题，移动的字体大小超小。
我的解决方案是：
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta name="x-apple-disable-message-reformatting">
<style type="text/css">
.bodyContent p {font-size: 18px; line-height: 140%;}
footer {font-size: 14px; }
footer img { width: 30px;}
@media (max-width: 480px) {
.bodyContent p {font-size:28px !important;}
.bodyContent .button {font-size: 34px !important; padding: 10px !important;}
footer {font-size: 22px !important; }
footer img { width: 50px !important;}
.headerimg {height: 80px !important;}
h3 {font-size: 32px !important;}
}
</style>
</head>
</html>
身体是：
<body class="bodyContent" style="border-top: 5px solid #248F8D; color: #444; font-weight: 300; font-family: Helvetica, Arial, Tahoma, sans-serif; background-color: white; margin: 0; padding: 0; width: 100%; box-sizing: border-box; line-height: 140%;">
我不知道为什么会发生这种情况，因为在其他电子邮件中，我将它简单化了，标准字体大小为16px或18px，它适用于网络和移动设备。
以上配置适用于iOS电子邮件，iMail和基于网络的Gmail（我也需要测试应用），但有些事情感觉不对劲。 28px字体大小的Helvetica在手机上似乎过大了不是吗？我认为这是考虑到视网膜显示，但我不确定这将如何适用于其他移动设备。视口和x-apple-disable-message-reformatting似乎没有做任何事情。
如果有帮助，这是电子邮件的RAW标题：
