mailto Link Builder

What it's for

Make a link that starts an email. Clicking a mailto: link opens the reader’s mail app with a new message, and the link can fill in the address, subject, body, cc and bcc. Spaces, line breaks and symbols such as & have to be encoded in a particular way, which this does for you.

For example, when a web page needs a “Report a problem” link that opens an email to support with the subject and a template already in place, fill in the fields here and paste the HTML into the page.

How to use it

Fill in any of To, Cc, Bcc, Subject and Body. Several addresses go in one field, separated by commas or semicolons. Link text is the clickable text in the HTML and Markdown versions; without it, the first To address is used.

The link, an HTML <a> tag and a Markdown link update as you type, each with a Copy button. Try it in your email app opens the link, so you can check it. To change an existing link, paste it into Read a link you have, and its parts are put into the fields.

Example

To help@example.com, subject Question about order 1042, and this body:

Hello,

I have a question about my order.

Thanks

The link is mailto:help@example.com?subject=Question%20about%20order%201042&body=Hello%2C%0D%0A%0D%0AI%20have%20a%20question%20about%20my%20order.%0D%0A%0D%0AThanks, 152 characters long.

Good to know

What happens on click depends on the reader’s device: with no mail app set up, nothing may happen, and some web mail and apps ignore bcc or cut off very long links (the message warns at 2,000 characters). Attachments can’t be added by a link. Addresses in a page can be collected by spammers, so a link on a public page is likely to bring some spam.
