| clientemail | The visitor-specified email address to be subscribed to the list. This should be a "text" input field. |
| listemail | The list subscription address. Generally, this is the name of the list followed by the string "-subscribe", the character "@" and the domain name. E.g., for a mailing list named "newsletter" at "example.com", "listemail" would be "newsletter-subscribe@example.com". This should be a "hidden" input field. |
| success_url | If this parameter is present, the subscriber will be redirected to the URL given as the parameter's value after the form is submitted (see below for an example). |
