Broadcasts (e-mail campaigns) of the site in ascending order of id (order=newest for the latest first), with their status, e-mail subject, sender, audience, schedule, A/B test and folder. Filters combine: every one given must match. started_since and started_before select by when sending first started (started_at), so a broadcast scheduled but not started yet is left out; created_since is when it was created.

Nested lists keep their first 5 entries and texts their first 200 characters (links stay whole); truncated names what was cut, get_broadcast has it whole. A page holds up to limit broadcasts; while next_cursor is set, pass it as cursor for the next page. For the numbers of a page of broadcasts call get_broadcasts_stats_by_broadcast with their ids.

Deleted broadcasts are not listed. A broadcast without an e-mail is listed with email_id, subject, preview_text and every field of sender null.

To keep a copy in sync, walk the whole list with the cursor and no filters once. After that, pass updated_since set to the start of the previous walk minus a margin of a few minutes, and merge by id. The margin is required: a change may be stamped slightly earlier than it becomes visible.

updated_at moves with a change of the broadcast, a change of its status by the user, the scheduler or the sender, the A/B result and a change or deletion of the broadcast's e-mail, except a change by the support team. It does not move with new statistics or a move to a folder. A deleted broadcast simply disappears. Repeat the full walk now and then to notice all of these.
