Frequently Asked Questions

Is this tool free to use?
Yes, completely free with no account required.
Does my data leave my device?
No. All link generation happens in your browser. Your email addresses and message are never sent to any server.
Does it work on mobile?
Yes. Generated mailto links open the native email app on iOS and Android.
What happens if the To field is empty?
The generated link starts with "mailto:" with no address, which opens a new compose window without a pre-filled recipient — useful for generic contact buttons.
Can I use multiple recipients in the To field?
Yes. Separate multiple addresses with commas: "a@example.com,b@example.com". Most email clients support this syntax.
