我在一个HTML文档中有几个mailto链接。
<a href="mailto:etc...">
我可以插入HTML格式的身体在mailto: href的一部分?
<a href="mailto:me@me.com?subject=Me&body=<b>ME</b>">Mail me</a>
请注意(2016)在iOS中，添加<i>和<b>标签用于简单的斜体、粗体格式是完全没问题的。

Whilst it may not be possible within the parameter of the URL, there is a cheeky solution which allows full HTML. The concept is that you have a hidden element on the page (I am using Bootstrap and Jquery in the example below) which is temporarily revealed and the HTML copied (as per here: How to copy text from a div to clipboard). Following that, you redirect the user to the Mail link so in effect all they then have to do is hit Paste within their designated mail program. I've only tested this on Linux/Thunderbird but the paste also works into Gmail web.
<div id="copyEmailText" class="d-none"><p><strong>This is some HTML</strong>. Please hit paste when your email program opens.</p>
function copyDivToClipboard(element) {
var range = document.createRange();
range.selectNode(element);
window.getSelection().removeAllRanges(); // clear current selection
window.getSelection().addRange(range); // to select text
document.execCommand('copy');
window.getSelection().removeAllRanges();// to deselect
}
$('#copyEmail').on('click',function(){
$('#copyEmailText').toggleClass('d-none');
copyDivToClipboard($('#copyEmailText')[0]);
window.location.href = 'mailto:?subject=Email subject text';
$('#copyEmailText').toggleClass('d-none');
})

有些事情是可能的，但不是所有的，例如你想要换行，而不是使用<br />使用%0D%0A
例子:
<a href="mailto:?subject=&body=Hello,%0D%0A%0D%0AHere is the link to the PDF Brochure.%0D%0A%0D%0ATo view the brochure please click the following link: http://www.uyslist.com/yachts/brochure.pdf"><img src="images/email.png" alt="EMail PDF Brochure" /></a>
It is worth pointing out that on Safari on the iPhone, at least, inserting basic HTML tags such as <b>, <i>, and <img> (which ideally you shouldn't use in other circumstances anymore anyway, preferring CSS) into the body parameter in the mailto: does appear to work - they are honored within the email client. I haven't done exhaustive testing to see if this is supported by other mobile or desktop browser/email client combos. It's also dubious whether this is really standards-compliant. Might be useful if you are building for that platform, though.
正如其他响应所指出的，在将encodeURIComponent嵌入到mailto:链接之前，还应该在整个正文上使用encodeURIComponent。
虽然不可能使用HTML来格式化你的电子邮件正文，你可以添加换行符，就像之前建议的那样。
如果你能够使用javascript，那么“encodeURIComponent()”可能会像下面这样使用…
var formattedBody = "FirstLine \n Second Line \n Third Line";
var mailToLink = "mailto:x@y.com?body=" + encodeURIComponent(formattedBody);
window.location.href = mailToLink;
这不是你想要的，但可以使用现代javascript在客户端创建一个EML文件，并将其传输到用户的文件系统，这应该会在他们的邮件程序中打开一个包含HTML的富电子邮件，如Outlook:
