How do mailto links work across different email clients?

Mailto links work with all major email clients including Gmail, Outlook, Apple Mail, and Thunderbird. Our generator automatically encodes special characters to ensure maximum compatibility across platforms.

Can I include multiple recipients in a mailto link?

Yes, you can include multiple recipients in TO, CC, and BCC fields. Separate multiple email addresses with commas or semicolons. However, note that some email clients may have limitations with very long recipient lists.

What special characters are automatically encoded?

Our tool automatically encodes all special characters including spaces (%20), ampersands (&), question marks (?), and other symbols to ensure your mailto links work properly in all browsers and email clients.

Is there a limit to the subject or body text length?

While there is no hard limit in our tool, we recommend keeping subject lines under 50 characters and body text concise for better email client compatibility and user experience.
