Filemail's main uploader (the one at can be pre-filled with custom values. You can do it by adding following query parameters to browser URL bar:

  • from
  • to
  • message
  • subject

Parameters values must be URL-encoded.

Example: https://[email protected],[email protected]&[email protected]&message=My%20test%20message&subject=Test%20subject

Note: the field "from" can be set only when you are not logged into Filemail. Once you are logged in - the email which you use as the login is always used as the "from" email.
