| ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `--compare`         | Include the prior equal-length period, populating compared\_to. Possible values: previous\_period.                                                                                                                                                                                                                                                                                                                                                                                                |
| `--from`            | First UTC day of the period, inclusive, in YYYY-MM-DD: the same window convention as the email statistics endpoints. Defaults to 30 days before to. It may be at most 30 days before to, which is also the default, so a request naming neither date is already at the limit. Asking for more answers 422: the page pairs these figures with Bird's own per-provider sending statistics, and those are kept for 30 days, so a longer period could only describe two different spans side by side. |
| `--response-schema` | Print the fields this command returns, then exit                                                                                                                                                                                                                                                                                                                                                                                                                                                  |
| `--to`              | Last UTC day of the period, inclusive, in YYYY-MM-DD. Defaults to today.                                                                                                                                                                                                                                                                                                                                                                                                                          |
