This is always possible

subscribe users user1@foo.com user2@bar.com user3@bar.com --list list@domain.org

Hi,

I have built to features, subscribe and unsubscribe users, as described above

*subscribe users user1@foo.com user2@bar.com user3@bar.com --list list@domain.org*

and

*unsubscribe users user1@foo.com user2@bar.com user3@bar.com --list list@domain.org*

The command prints a success message on successful completion of action else prints an error message and continues execution. These feedback messages can be suppressed by using a --quiet switch.

subscribe users user1@foo.com user2@bar.com user3@bar.com --list list@domain.org user1@foo.com subscribed to list@domain.org user2@foo.com subscribed to list@domain.org user3@foo.com subscribed to list@domain.org

The commands accept one or more user emails as arguments.
