What is a mailto: link?

A mailto: link is an HTML hyperlink that opens the visitor's default email client with one click — recipient, subject, and body already filled in. It's the fastest way to add a "Contact Us" or "Send Feedback" button to any page without needing a backend form.

Why use CC & BCC?

CC loops in a colleague automatically. BCC silently archives the email to a shared inbox — useful for support teams tracking inbound contacts.

URL length limits

Email clients cap mailto URLs around 2,000 chars. Very long pre-filled bodies get silently truncated. Keep body text concise or use a contact form for long messages.

When NOT to use mailto:

Mailto links expose your email address to scrapers. For public pages with high spam risk, a contact form backed by a server is safer. Use mailto for internal tools, portals, or known-audience pages.

Multiple recipients

Add multiple addresses to the To field — each becomes a separate recipient. Most email clients support comma-separated addresses inside a single mailto: link.
