E-mail numbers of all broadcasts of the site, without filters deleted ones included, split into buckets of interval. broadcast_ids, status, search, created_since, started_since, started_before and folder_id narrow the count to the live broadcasts that match every one given; matched says how many, and matched: 0 means no broadcast matched. Buckets are consecutive days, calendar weeks (Monday to Sunday) or calendar months; the first and the last are cut to the period. Every bucket is present, an empty one with zeros.

Each number counts the events dated in the period on its own, so the numbers are independent: a bounce or an open of an e-mail sent before the period counts here too.

Every number counts e-mails, one e-mail being one message to one recipient, and each e-mail at most once per metric: send e-mails sent, including those rejected on sending; bounce e-mails that bounced or were rejected on sending; deliver is send minus bounce, never below zero; open e-mails opened; click e-mails with at least one link clicked; unsubscribe e-mails whose recipient unsubscribed through them; complaint e-mails reported as spam through the recipient's mail provider. rates next to each total gives the delivery, open, click, click-to-open, unsubscribe, complaint and bounce rates, rounded to 4 places; a rate is null when its denominator is 0, as it is undefined, not zero.
