我曾经打过HTML电子邮件之战。以下是我的一些关于如何在电子邮件客户端之间实现最大兼容性的设计技巧。

Inline styles are you best friend. Absolutely don't link style sheets and do not use a <style> tag (GMail, for example, strips that tag and all it's contents). Against your better judgement, use and abuse tables. <div>s just won't cut it (especially in Outlook). Don't use background images, they're spotty and will annoy you. Remember that some email clients will automatically transform typed out hyperlinks into links (if you don't anchor <a> them yourself). This can sometimes achieve negative effects (say if you're putting a style on each of the hyperlinks to appear a different color). Be careful hyperlinking an actual link with something different. For example, don't type out http://www.google.com and then link it to https://gmail.com/. Some clients will flag the message as Spam or Junk. Save your images in as few colors as possible to save on size. If possible, embed your images in your email. The email won't have to reach out to an external web server to download them and they won't appear as attachments to the email.

最后，测试，测试，测试!每个电子邮件客户端都与浏览器的工作方式不同。

除了这里发布的答案，一定要阅读这篇文章:

Campaign Monitor有一个很好的支持矩阵，详细说明在各种邮件客户端中支持什么，不支持什么。

您可以使用Litmus这样的服务来查看电子邮件如何在多个客户端之间出现，以及它们是否被过滤器捕获等等。

“胆小鬼。我将使用样式表制作一个HTML页面，然后使用jQuery将样式表应用到每个元素的样式attr。就像这样:

var styleAttributes = ['color','font-size']; // all the attributes you've applied in your stylesheet
for (i in styleAttributes) {
    $('body *').css(styleAttributes[i],function () {
        $(this).css(styleAttributes[i]);
    });
}

然后复制DOM并在电子邮件中使用它。

邮件黑猩猩有一篇很好的文章，告诉你什么是不该做的。(我知道这听起来和你想要的完全相反)

总的来说，你所学到的所有不好的网页设计实践似乎都是html电子邮件的唯一选择。

基本原则是:

为图像提供绝对路径(例如。 https://stackoverflow.com/random-image.png) 使用表格进行布局(从未想过 我建议这样做!) 使用内联样式(和老式css) 而且，最多2.1，盒影 不会工作，例如;))

只要在尽可能多的电子邮件客户端中进行测试，或者像上面其他人建议的那样使用Litmus !(credit to Jim)

邮件黑猩猩做了一个伟大的工作，使这个工具可用的社区。

它应用你的CSS类到你的html元素内联为你!
