Opt-out lists

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.
