Returns how often the domain's mail is reported as spam by Gmail recipients, as Google Postmaster measures it: the rate for the period and a time series for charting.

This is Google's number for Gmail-received mail only. The feedback-loop complaint rate across all providers is a Bird-measured figure served by the email statistics endpoints; the two count different mail and are rendered as separate lines, never combined. For a domain without a completed Google Postmaster connection, sections report not_configured with a setup path, not an error.

API-key calls require Insights preview access for your organization.

Abfrageparameter

sending_domainstring

The sending domain to report on: one of the workspace's verified sending domains, exactly as it appears there. A domain that is not verified in this workspace answers not-found.

fromstring

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.

tostring

Last UTC day of the period, inclusive, in YYYY-MM-DD. Defaults to today.

group_bystring

Bucket size for the series. Defaults to day.

Possible values: day, week, month

comparestring

Include the prior equal-length period, populating compared_to and the rate's delta.

Possible values: previous_period

Antwort-Payload

resource
string
erforderlich

Which resource this response is, echoed for self-description.

domain
string
erforderlich

The sending domain the figures describe.

measurement
object

How the figures were measured. Present only where a figure was weighted or drawn from a named set of sources, which today means placement and the industry benchmark. Absent on the reputation resources and on a live lookup, neither of which weights anything.

Untergeordnete Attribute anzeigen
generated_at
string
erforderlich

When these figures were computed. The measurement service's own stamp where it publishes one; on the resources Bird derives from daily rates it has none to publish, and this is when Bird computed them.

freshness
object
erforderlich

How current the figures are. Freshness differs per resource (authentication data can lag a day or more while blocklist lookups are near real time), so any "as of" label binds from this field, never from a fixed string.

Untergeordnete Attribute anzeigen
freshness.as_of
nullable string
erforderlich

The most recent UTC day the figures include, or null for a live lookup that has no measurement window.

freshness.lag_hint
nullable string
erforderlich

How far behind real time this resource usually runs. A lowercase identifier rather than a display label, so pick your own wording for it, and treat the set as open: the measurement names a hint per resource and can add one without notice.

Null when the measurement reports no hint, which several resources do: show the figures without an age rather than inventing one.

Possible values (may grow over time): daily, nightly, near_real_time

cached_at
string

Present when the response was served from a short-lived copy rather than fetched for this request: when that copy was fetched.

window
object
erforderlich

The period every figure in the response covers: whole UTC calendar days, inclusive on both ends. The same window convention the email statistics endpoints use, so figures from the two sources describe the same days and can be combined without adjustment.

Untergeordnete Attribute anzeigen
compared_to
object

The prior equal-length period the delta figures compare against. Present only when the request asked for a comparison.

Untergeordnete Attribute anzeigen
rate
object
erforderlich

The rate at which the domain's mail is reported as spam, as Google Postmaster measures it.

Untergeordnete Attribute anzeigen
series
object
erforderlich

The complaint-rate series, at the grain named in window.group_by. Index by date, never by position.
