标准方式来检测移动邮件客户端？ [英] Standard way to detect mobile mail client?

问题描述

这个问题类似于标准方式来检测基于http请求的Web应用程序中的移动浏览器除了邮件客户端。例如，如果在内置的iPhone邮件客户端上打开电子邮件，它将显示特别为iPhone格式化的邮件版本。如果在平板电脑或桌面上打开，它将显示为完整的电子邮件的完整尺寸版本。这在原理上类似于网站的移动友好版本，通过检测用户代理自动加载 - 但对于电子邮件客户端。

This question is similar to "Standard way to detect mobile browsers in a web application based on the http request" except for mail clients. For instance, if an email message is opened on the built-in iPhone mail client it will display a version of the message specially formatted for the iPhone. If opened on an tablet or desktop it will display as the complete, full-size version of the email. This is similar in principle to web sites that have mobile-friendly versions of the site that load automatically by detecting the user-agent - but for email clients.

可以检测用于打开电子邮件并相应地格式化邮件的邮件客户端？

So - is it possible to detect the mail client being used to open an email and format the message accordingly? Perhaps a way to detect the screen resolution?

推荐答案

您可以尝试应用 @media css查询定位特定浏览器（如移动设备）。在 campaignmonitor帮助网站上有一个很好的介绍，但请注意，它可能只在手中支持充满了浏览器和设备，iOS幸运：）

You can try to apply @media css queries that target specific browsers like mobile devices. There is a good introduction on the campaignmonitor help website but be aware, it probably is only supported in a hand full of browsers and devices, iOS being on of them luckily :)

基本上你是定义css样式，目标特定的屏幕宽度，以便你可以优化您的电子邮件有限的屏幕空格。

Basically you are defining css styles that target specific screen widths so that you can optimize your email for limited screen space.

@media only screen and (max-device-width: 480px) { ... }

当谈论真正的检测和显示完全不同的电子邮件时，这真的不可能，因为你在谈论javascript，电子邮件，甚至可能不会在所有电子邮件客户端的99％工作。但是你可以用@media查询一个无聊的方式。

When talking really detection and displaying a totally different email, that's really impossible since you are talking about javascript there and that's not done in emails and probably won't even work in 99% of all email clients. But you can go a loooong way with @media queries.
