This section covers adding list members via email.
To add list members via email, you send an email to email@example.com with nothing in the Subject: line and in the message body put the following:
QUIET ADD listname username@domain Firstname Lastname
You could "invite" someone to join a list. They will receive an email asking them to confirm. Once that is done, the person will be added.
INVITE listname username@domain Firstname Lastname
