Get aggregate email statistics
Returns a single-row aggregate across the requested period covering delivery, bounce, complaint, open, and click counts plus the derived rates, along with processing, delivery, and total latency percentiles (p50/p95/p99). Suitable for KPI tiles, campaign reports, and email digests; the daily and hourly endpoints have the same metrics per time bucket.
The aggregate is computed against event time (not send time), so engagement received during the period for messages sent earlier is included. Rate fields are null when their denominator is zero.
The window grain follows the form of from and to: calendar days (YYYY-MM-DD, up to 365 days) or RFC 3339 instants (hour grain, up to 720 hours, 30 days). A rolling window such as the last 24 hours is a single request. Mixing the two forms returns 422. Set timezone to compute day and hour boundaries in a local zone instead of UTC, and compare=previous_period to include the preceding equal-length window in the same response.
Request

Query parameters
Inclusive start of the window: a calendar day (YYYY-MM-DD) or an RFC 3339 instant (rounded down to the hour). Interpreted in timezone (a calendar day names a local day; an instant is rounded down to the local hour), or in UTC when timezone is omitted. A numeric UTC offset (for example +05:45) is rejected when timezone is set; use a calendar day or a Z (UTC) instant. Must use the same form as to. Defaults to 30 days before to for day windows, or 168 hours (7 days) before to for hour windows, when omitted.
Inclusive end of the window: a calendar day (YYYY-MM-DD) or an RFC 3339 instant (rounded down to the hour). Interpreted in timezone (a calendar day names a local day; an instant is rounded down to the local hour), or in UTC when timezone is omitted. A numeric UTC offset is rejected when timezone is set; use a calendar day or a Z (UTC) instant. Must use the same form as from. Defaults to today for day windows, or the current hour for hour windows, in that timezone, when omitted. Day windows may not exceed 365 days; hour windows may not exceed 720 hours (30 days).
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.
Restrict the statistics to a category or a comma-separated union of categories: transactional or marketing. Mutually exclusive with the other dimension filters; only one may be set per request.
Restrict the statistics to a sending domain or a comma-separated union of sending domains (the part of the From address after @). Mutually exclusive with the other dimension filters; only one may be set per request.
Restrict the statistics to a tag. Use name to match any value of a tag, or name:value for a specific pair (for example campaign:spring_launch). To combine values of one tag name, separate complete pairs with commas, such as campaign:spring,campaign:summer. Different tag names cannot be combined. Mutually exclusive with the other dimension filters; only one may be set per request.
Restrict the statistics to a sending IP or a comma-separated union of IPs. Mutually exclusive with the other dimension filters; only one may be set per request. A sending IP is assigned only after a message reaches delivery, so this filter reports delivery-side metrics only. Accepted, processed, rejected, complaint, and engagement counts are 0, and processing latency is null. Complaint, open, and click rates are 0 when deliveries exist and null otherwise.
Restrict the statistics to a recipient mailbox domain or a comma-separated union of domains (the part of the recipient address after the @, for example gmail.com). Mutually exclusive with the other dimension filters; only one may be set per request.
Restricts the statistics to a template or a comma-separated union of templates, identified by ID (emt_…) or name. This parameter is mutually exclusive with other dimension filters.
Set to previous_period to also include the same statistics for the immediately preceding window of equal length, plus the change between the two, so you can show "+X% vs last period" without a second request.
Headers
Workspace context for the request. Required for dashboard authentication and master keys. Workspace keys and access tokens already identify their workspace; send that workspace or omit the header. A different one is rejected.
Organization context for the request. Required for dashboard authentication. An API key or access token carries its own organization, so send either that organization or no header at all; a different one is rejected.
Response
Aggregate summary for the requested period.
