What is a mailto link and how does it work?

A mailto link is an HTML link (` `) that triggers the user's default email program when clicked, pre-filling specified email fields like recipient, subject line, and body template.

How do I add multiple email recipients to a mailto link?

Separate multiple email addresses in the 'To', 'CC', or 'BCC' field with a comma (e.g. `sales@domain.com,support@domain.com`). Avoid spaces between email addresses for maximum client compatibility.

Why are there %20 and %0A characters in the generated mailto link?

URLs cannot contain plain spaces or line breaks. Web standards require spaces to be encoded as `%20` and line breaks as `%0A`. Our generator handles this encoding automatically.

Can I use line breaks in the mailto body template?

Yes! Enter line breaks normally in our Body text field. The tool encodes them as `%0A` so your paragraphs render cleanly inside Gmail, Outlook, or Apple Mail.

Do mailto links work on mobile devices?

Yes. When tapped on iOS or Android devices, mailto links open the default email app (Apple Mail, Gmail, Outlook Mobile) with all fields pre-populated.

How does Wootomatic use mailto links for custom business automation?

Wootomatic builds automated email intake funnels and CRM workflows that parse incoming emails from custom mailto links directly into lead stages and automated auto-responders.
