Mailto Link Builder

Use this Mailto Link Builder to create prefilled email links with recipients, cc, bcc, subject, and body text. It is useful for contact pages, support links, documentation, onboarding flows, static sites, and quick HTML snippets.

The tool generates both a raw mailto: URL and a ready-to-copy HTML anchor so you can place the link directly into a page, Markdown document, or template.

What This Tool Does

This builder supports common email-link fields:

• Add one or more recipients
• Add cc and bcc recipients
• Prefill an email subject
• Prefill a multi-line body
• Copy the mailto: URL or HTML link

Why Mailto Links Need Care

Mailto URLs look simple, but subjects, body text, commas, spaces, and line breaks need URL encoding to work consistently. Manually writing a long mailto link can produce broken links or missing fields in some email clients.

A builder makes the final URL easier to inspect before it is added to a website or shared with a team.

Common Use Cases

• Creating contact links for static websites
• Building support email links with a prefilled subject
• Adding feedback links to documentation
• Creating onboarding or sales email shortcuts
• Preparing HTML email links without writing the URL by hand

Example

<a href="mailto:[email protected]?subject=Project%20question">Email us</a>

Notes for Developers

• Email clients may handle long body text differently
• Do not include sensitive data in a public mailto URL
• Keep prefilled body text short for better compatibility
• Test links in the target browser or email client when possible
