How to Code Mailto Links in HTML

An HTML mailto link is a specialized anchor tag that allows web visitors to send an email directly by tapping a link. Instead of linking to another webpage, the href attribute specifies a mailto: URI scheme, forcing the operating system to open the default system email client instantly.

Structure of a Complex Mailto URL

A basic email link looks like this: <a href="mailto:[email protected]">Contact Us</a>. To add parameters like Subject, CC, BCC, or Body, we use URL query parameters:

Use cc=emailaddress to copy additional recipients.
Use bcc=emailaddress to blind copy recipients secretly.
Use subject=Text to pre-fill the email's subject line header.
Use body=Text to structure a standard email message draft.

The first parameter must be appended with a question mark (?), and subsequent fields must be chained with an ampersand (&).

Encoding Line Breaks in Email Body

You cannot use standard line breaks in your HTML code block inside a mailto URI. Spacing and returns must be written as %20 (for space) and %0A or %0D%0A (for line feeds). This generator automatically executes all required escaping algorithms on the fly as you write.
