How to Use

  1. 1 Enter one or more recipient email addresses
  2. 2 Optionally add Cc and Bcc recipients
  3. 3 Type a subject line
  4. 4 Write the message body — line breaks are preserved
  5. 5 Copy the mailto link, or the ready-made HTML or Markdown

Features

  • Correct percent-encoding (spaces as %20, line breaks as %0D%0A)
  • Multiple recipients, plus Cc and Bcc
  • Pre-filled subject and body
  • Ready-to-paste HTML anchor and Markdown link
  • Basic email validation flags obvious typos
  • Live 'test this link' button to open your email client

Why it Matters

A hand-written mailto link breaks the moment a subject contains a space, an ampersand, or a line break. Generating it correctly means your 'Email us' button opens a clean, pre-filled draft in any client — no broken subjects, no dropped body text.

What this tool does

The Mailto Link Generator builds a correct mailto: URL from a recipient list, Cc, Bcc, subject, and body. It percent-encodes everything properly and gives you the raw link, a ready-to-paste HTML anchor, and a Markdown link — so your “Email us” button opens a clean, pre-filled draft in any client.

How it works

The recipients sit before the ?; Cc, Bcc, subject, and body become encoded header fields after it. Spaces are encoded as %20 (never +) and line breaks as %0D%0A, exactly as RFC 6068 requires, so subjects and multi-line bodies survive intact.

Privacy

Everything runs locally in your browser. Nothing you type is uploaded, logged, or stored.

Frequently Asked Questions

What is a mailto link?
A mailto link is a URL that starts with 'mailto:' and opens the user's default email client with a new message. You can pre-fill the recipient, Cc, Bcc, subject, and body. Clicking it never sends anything automatically — it just opens a draft.
Why do I need to encode the subject and body?
Subjects and bodies often contain spaces, ampersands, equals signs, or line breaks, which have special meaning in a URL. Without encoding, the link breaks — the subject gets cut off or the body is lost. This tool percent-encodes everything correctly per RFC 6068, using %20 for spaces and %0D%0A for line breaks.
Can I add multiple recipients or Cc and Bcc?
Yes. Enter several addresses separated by commas in any field. The tool de-duplicates them, validates each, and places Cc and Bcc as proper header fields in the link.
Will the link work in Gmail and Outlook?
Yes. Standard mailto links are honoured by desktop and web clients, including Gmail and Outlook, provided the user has set a default mail handler. Body line breaks and subjects render correctly because they're properly encoded.
Is my data stored anywhere?
No. The link is built entirely in your browser. Nothing you type is uploaded, logged, or stored — refreshing the page clears everything.
