Get daily sending statistics
Returns one row of aggregate sending statistics per calendar day for the workspace: UTC days by default, or your local days when timezone is set. Days with no activity are included with zero counts, so the series charts without client-side gap handling. Suited to charts and trend lines; for per-message exact accounting use the message detail endpoints.
Rows use event time. For example, a complaint received on Wednesday for a message sent the prior Monday is counted in Wednesday's row.
The maximum window is 365 days; requesting a longer range returns 422.

Query parameters
Start date (inclusive), YYYY-MM-DD. Interpreted as a calendar day in timezone (a UTC day when timezone is omitted). Defaults to 30 days before to when omitted.
End date (inclusive), YYYY-MM-DD. Interpreted as a calendar day in timezone (a UTC day when timezone is omitted). Defaults to today in that timezone when omitted. Window may not exceed 365 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.
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
Daily aggregate stats for the requested period.
