我不知道邮件客户端的比例，尽管现在文本模式客户端也支持 HTML。然而，有一个很好的理由不发送纯 HTML 邮件。来自我的 SpamAssassin 报告之一：
1.9 MIME_HTML_ONLY BODY：邮件仅包含 text/html MIME 部分
除非您希望将邮件放入垃圾箱，否则不要发送纯 HTML 邮件。
I don't know about mail client percentages, although even text-mode clients support HTML these days. There is however a very good reason to NOT send HTML-only mail. From one of my SpamAssassin reports:
1.9 MIME_HTML_ONLY BODY: Message only has text/html MIME parts
Unless you want your mail to be dropped in the trashcan, do not send HTML-only messages.
这在很大程度上取决于您的目标人群，但目前非 HTML 电子邮件收件人的数量通常相当小。那些在电子邮件客户端中明确关闭 HTML 支持的人通常知道他们在做什么，并且有充分的理由（并期望他们得到什么）。
如果您正在谈论向某个网站的用户列表发送电子邮件，那么一个常见的建议是在 UI 中进行用户设置，让他们可以指定 HTML 或纯文本电子邮件（甚至选择退出，但那就是你的电话）。这意味着制作相同的电子邮件/模板两次，这可能比满足您的需求所值得的更多努力，但这是重要的。
It'll depend a lot on your target demographic, but more often than not the number of non-HTML email recipients these days is fairly small. And those who explicitly turn off HTML support in their email client usually know what they're doing and have a good reason (and expect what they get).
If you're talking about sending emails to a list of users for, say, a website then one common suggestion is to have a user setting in the UI where they can specify HTML or text-only emails (or even opt out, but that's your call). It means making the same emails/templates twice, which may be more effort than it's worth for your needs, but it's something.
发送纯 HTML 电子邮件当然不安全。无论电子邮件客户端对 HTML 的支持如何，都存在无法衡量的用户偏好。另一件需要记住的事情是，大量移动设备更喜欢阅读文本版本，因为它们的 HTML 渲染充其量只是低于标准。
您应该发送电子邮件的两个版本。没有理由不这样做。

It is certainly not safe to send HTML-only e-mails. Regardless of e-mail client support for HTML, there are user preferences that aren't possible to measure. Another thing to keep in mind is the huge number of mobile devices that prefer to read the text version, as their HTML rendering is sub-par at best.
You should be sending out both versions of your e-mail. There is no reason not to.
