Lists that keep opt-outs separate, for example one per brand or per type of message.

Every account has a default list, created automatically. Sends are checked against the default
list unless the request names a different one with `opt_out_list_id` or `opt_out_list_name`,
so someone who opts out of marketing can still get appointment reminders. Lists are created
in the web app; over the API you can read them and the opt-outs they hold. See
[Opt-outs](/guides/opt-outs/).
