Mailto link generator
What this mailto link generator does
It composes mailto: URIs with optional to, cc, bcc, subject, and body query fields, then offers an <a href> snippet for your page. Mail clients and OS handlers parse these links locally—length limits and encoding rules vary, so very long bodies may truncate silently. Percent-encoding reserved characters is mandatory for stable behavior across Outlook, Gmail, and mobile defaults.
When to use it
Use it for support pages ("Email us about billing"), mail-share buttons, or QA templates that open a prefilled bug report. Test on target devices. Pair tricky query strings with URL encoder, and avoid stuffing secrets—mailto links are visible in HTML source.
Worked example
A feedback link adds subject=Bug%20report and a body skeleton so users send structured traces instead of blank threads.
Frequently asked questions
Multiple recipients?
Comma-separate addresses per RFC guidance; some clients mishandle spaces—trim carefully.
Why breaks disappeared?
Use %0D%0A for reliable newlines in bodies.
Can I attach files?
mailto cannot reliably attach binaries; use uploads or cloud links instead.
