Free Mailto Link Generator — Create Click-to-Email Links with Subject & Body

0 of 0 ratings

What Is a Mailto Link Generator?

A mailto link generator creates clickable HTML links that automatically open the user's default email client with pre-filled fields — including the recipient address, subject line, CC/BCC recipients, and even the email body. Instead of manually coding the mailto: URI syntax, this tool builds the correctly encoded link for you in seconds.

Why Mailto Links Matter

Mailto links are one of the simplest ways to encourage website visitors to contact you via email. They remove friction from the communication process:

  • One-click contact — Visitors don't need to copy your email address; clicking the link opens a ready-to-send email
  • Pre-filled fields — You can set the subject line, body text, and CC/BCC recipients automatically, saving the sender time
  • Universal compatibility — Mailto links work on every browser, operating system, and email client
  • No server required — Unlike contact forms, mailto links don't need backend processing or form handling
  • CTA effectiveness — A well-crafted mailto link with a pre-set subject line increases response rates by reducing effort

Mailto Link Syntax Explained

Basic Format

The basic mailto link format is: mailto:email@example.com. You can add parameters using a question mark and ampersands:

  • ?subject=Hello — Sets the email subject
  • &body=Your message here — Pre-fills the email body
  • &cc=another@example.com — Adds CC recipients
  • &bcc=hidden@example.com — Adds BCC recipients

URL Encoding

Special characters in subjects and body text must be URL-encoded (e.g., spaces become %20, line breaks become %0A). Our generator handles all encoding automatically so you don't have to worry about broken links.

How to Use Our Mailto Link Generator

  1. Enter the recipient email address
  2. Optionally add a subject line
  3. Optionally add CC and BCC recipients
  4. Optionally write a body message
  5. Click generate to get your ready-to-use mailto link
  6. Copy the HTML code and paste it into your website

Common Use Cases

  • Website contact buttons — Add "Email Us" links to your site header, footer, or contact page
  • Customer support — Create pre-filled support request links with subject lines like "Support Request"
  • Email signatures — Include clickable email links in your professional signature
  • Marketing campaigns — Generate tracked feedback links with pre-set subjects for segmentation
  • Event invitations — Create RSVP links that open an email with the event name and confirmation template

Best Practices

  • Keep subjects short and clear — Pre-filled subjects help you organize incoming emails and improve open rates
  • Don't put sensitive info in mailto links — The full URL (including body text) is visible in the page source
  • Combine with contact forms — Offer both a mailto link and a web form for users who prefer not to use email clients
  • Test across clients — Verify your mailto link works in Gmail, Outlook, Apple Mail, and mobile email apps
  • Use for internal tools too — Mailto links in dashboards and intranets speed up team communication

Frequently Asked Questions

Do mailto links work on mobile devices?

Yes. On mobile devices, clicking a mailto link opens the default email app (Gmail, Apple Mail, Outlook, etc.) with all pre-filled fields intact. The behavior is the same as on desktop browsers.

Can I add line breaks in the mailto body?

Yes. Line breaks in mailto body text are encoded as %0A (or %0D%0A for Windows-style line breaks). Our generator handles this encoding automatically when you type multi-line body text.

Are mailto links bad for spam?

Exposing email addresses in mailto links can make them targets for spam bots that crawl HTML source code. To mitigate this, consider using JavaScript obfuscation, CAPTCHA-protected contact forms, or encoding the email address in your HTML.

Can I add multiple recipients to a mailto link?

Yes. Separate multiple "To" addresses with commas: mailto:one@example.com,two@example.com. You can also add multiple CC and BCC addresses the same way.
