Returns aggregate delivery and engagement counts grouped by broadcast for the requested period, so each broadcast's deliverability and engagement can be compared side by side. Only messages sent as part of a broadcast appear here. One-off and transactional sends are not included, so a workspace that has not sent broadcasts returns an empty list rather than an error.

Rows are ranked by the sort metric (default processed) descending and paginated with the requested limit (default 50, hard maximum 200). Rows are computed against event time (not send time), so engagement received during the period for messages sent earlier is included.

The maximum window is 365 days. Requesting a longer range returns a 422. Aggregate statistics remain available after the underlying message activity details expire. Counts and latency percentiles are approximate and may lag newly received activity; data_as_of reports refresh freshness when available. Historical results include only activity captured before those details expired.

Parameter Kueri

starting_afterstring

Cursor from the next_cursor field of a previous list response. Returns items immediately after the cursor position in the current sort order.

ending_beforestring

Cursor from the prev_cursor or refresh_cursor field of a previous list response. Returns items immediately before the cursor position in the current sort order. prev_cursor returns the preceding page. refresh_cursor anchors at the first row of that response, which on a newest-first sort is how to fetch the items that have appeared since.

fromstring

Start date (inclusive) in YYYY-MM-DD, interpreted as a calendar day in timezone (UTC when omitted). Defaults to 30 days before to when omitted.

tostring

End date (inclusive) in YYYY-MM-DD, interpreted as a calendar day in timezone (UTC when omitted). Defaults to today in that timezone when omitted. Window may not exceed 365 days.

timezonestring

IANA timezone identifier used to group statistics, for example Asia/Kathmandu. The default is UTC. Day and hour boundaries, including the default window when from and to are omitted, follow this timezone. When this parameter is set, pass from and to as calendar days or Z instants instead of timestamps with explicit UTC offsets.

categorystring

Not supported on breakdown endpoints. Supplying it returns a 422. To compare categories, use GET /v1/email/stats/categories. The summary, daily, and hourly statistics accept category as a filter.

sortstring

Metric to rank rows by, applied descending. Any count or rate in the response may be used; rows whose rate is undefined (zero denominator) sort last. Defaults to processed.

Possible values: processed, delivered, bounced, complained, deferred, rejected, oob_bounces, bounces.hard, bounces.soft, bounces.admin, bounces.block, bounces.undetermined, opens, opens_non_prefetched, unique_opens, unique_opens_non_prefetched, clicks, unique_clicks, unsubscribes, delivery_rate, bounce_rate, complaint_rate, open_rate, click_rate, unsubscribe_rate, bounces.hard_rate, bounces.soft_rate, bounces.admin_rate, bounces.block_rate, bounces.undetermined_rate

limitinteger

Maximum number of broadcast rows to return, ranked by the sort field descending.

Payload Respons

period
object
wajib

The date range the response covers (echoed back from the request), plus data_as_of, the freshness boundary the data is current to.

Tampilkan atribut turunan
data
array of object
wajib

Broadcast breakdown rows, ranked by the sort metric (default processed) descending. Empty when no broadcast messages were active in the period.

Tampilkan atribut turunan
data.broadcast_id
string
wajib

The broadcast this row covers, the same ID the broadcast endpoints return. Only mail sent as part of a broadcast has a broadcast ID, so one-off and transactional sends do not appear in this breakdown at all.

data.delivery

Tampilkan atribut turunan
data.engagement

Tampilkan atribut turunan
data.engagement.opens
integer
wajib

Distinct open events, counting repeat opens from the same recipient and opens auto-fetched by inbox privacy features (such as Apple Mail Privacy Protection and the Gmail image proxy).

data.engagement.opens_non_prefetched
integer
wajib

Distinct open events excluding those auto-fetched by inbox privacy features. Same event-counting semantics as opens (repeat opens from the same recipient count separately), with prefetched opens removed.

data.engagement.unique_opens
integer
wajib

Distinct recipients who opened at least once, including opens auto-fetched by inbox privacy features.

data.engagement.unique_opens_non_prefetched
integer
wajib

Distinct recipients who opened at least once, excluding opens auto-fetched by inbox privacy features. This is the numerator used for open rate, so iOS-heavy audiences (Apple Mail Privacy Protection and similar) do not inflate it.

data.engagement.clicks
integer
wajib

Distinct click events, counting repeat clicks from the same recipient.

data.engagement.unique_clicks
integer
wajib

Distinct recipients who clicked at least once.

data.engagement.unsubscribes
integer
wajib

Distinct unsubscribe events, recorded via the list-unsubscribe header or the footer link.

data.engagement.open_rate
nullable number
wajib

Distinct non-prefetched openers relative to effectively delivered recipients in the same scope, computed as unique_opens_non_prefetched / delivery.effective_delivered; on rows without an effective_delivered field (the mailbox-provider breakdowns) the denominator equals delivery.delivered. The numerator excludes opens auto-fetched by inbox privacy features. Opens are attributed by event time, so engagement earned by earlier deliveries can push the rate above 1. Null when the denominator is zero.

data.engagement.click_rate
nullable number
wajib

Distinct clickers relative to effectively delivered recipients in the same scope, computed as unique_clicks / delivery.effective_delivered (delivery.delivered on rows without an effective_delivered field). Clicks are attributed by event time, so engagement earned by earlier deliveries can push the rate above 1. Null when the denominator is zero.

data.engagement.unsubscribe_rate
nullable number
wajib

Unsubscribe events relative to effectively delivered recipients in the same scope, computed as unsubscribes / delivery.effective_delivered (delivery.delivered on rows without an effective_delivered field). Unsubscribes are attributed by event time, so the rate can exceed 1. Null when the denominator is zero.

data.latency
object
wajib
Tampilkan atribut turunan
total
integer
wajib

Total number of distinct broadcasts with activity in the period, regardless of limit. Pass next_cursor as starting_after to request the next page.

next_cursor
nullable string
wajib

Cursor for the next page. Pass back as starting_after to advance forward. null when no next page exists.

prev_cursor
nullable string
wajib

Cursor for the previous page. Pass back as ending_before to step backward. null when no previous page exists.

refresh_cursor
nullable string
wajib

Refresh anchor, the first row of this response. Pass back as ending_before to fetch what precedes it in the current sort order. On a newest-first sort those are the items that have appeared since; on any other sort they are the items that sort earlier, so refreshing such a list means re-fetching it instead. Non-null whenever data is non-empty; null only on an empty page. Distinct from prev_cursor.
