Metrics
Reach Email logs copious amounts of statistical, real-time data about message processing, message disposition, and campaign performance.
This reporting data is available in the "Insights" page (under the "Developer" / "Channels" / "Email" section) in the app or through the Metrics API.
The Metrics API provides a variety of endpoints enabling you to retrieve a summary of the data, data grouped by a specific qualifier, or data by event type. Within each endpoint, you can also apply various filters to drill down to the data for your specific reporting needs.
Data retention
Metrics API data is retained for 6 months.

Note: For a given request, average first attempt delivery latency can be calculated as total_delivery_time_first / count_delivered. A similar calculation holds for total_delivery_time_subsequent.
Precision Parameter
When the precision parameter is specified for aggregate metric requests, the bounds of the time window (from, to) are rounded to the nearest time matching the precision. For example, requesting data between 4:22 to 6:37 would return results within the following time windows:
1min
04:22:00 - 06:36:59
24 hours
5min
04:20:00 - 06:39:59
24 hours
15min
04:15:00 - 06:44:59
48 hours
hour
04:00:00 - 06:59:59
31 days
day
00:00:00 - 23:59:59
No max
Time-series Metrics
When the precision parameter is specified for the time-series request, it reflects the period of time the data is grouped by. The same max time window ranges apply for time-series requests as do aggregate requests. Precisions 12hr, week, and month may also be used for time-series requests.
Filters
Metric data can be filtered by using query parameters in the query component of the request URI. Each Metrics endpoint specifies certain filters that can be set as query parameters. The exact filters and query parameters available to each route are listed in the respective route's "parameters" section below. The filters can be specified using either a simple or advanced query syntax.
Simple Filters
Simple query filters can be specified as key-value pairs in the request URI and multiple values can be listed with a delimiter separating them. For example metrics can be limited to sending domains equal to bird.com or example.org with the following query string: ?sending_domains=bird.com,example.org
Advanced Filters
The Metrics API allows for more advanced data filtering with multiple conditions, groupings, and comparators via the query_filters query parameter.
The value of the query_filters query parameter must be structured as a URL-encoded JSON object. The Metrics API uses JSON Schema to define and validate advanced filters. Advanced Filter requests that do not adhere to the schema will result in a 400 error response. Specific schema violations will be attached to the validationErrors property of the error response. The exact schema can be retrieved through the /deliverability/query-filters-schema endpoint. See Advanced Query JSON Schema.
Please note, advanced filters cannot be used in conjunction with simple filters. Simple filters will be ignored if the query_filters parameter is used. e.g. in ?domains=mailing.com&query_filters={}, the domains query parameter will be ignored. Other query parameters like from, to, metrics, limit, etc., will be processed as expected.
Groupings Structure
The JSON object consists of a root level "groupings" array containing compare objects. Multiple compare groups are evaluated such that the relationship between them is an AND operation.
Example:
{
"groupings": [
{
... compare group
},
{
... compare group
}
]
}
Compare Group
The compare objects have a single logical comparison operator (OR or AND) that will be used to compare all of the filter conditions in the group.
Example:
{
"AND": {
"domains": {
"eq": [ "gmail.com", "yahoo.com", "hotmail.com" ],
"like": [ "mail" ]
},
"sending_domains": {
"notEq": [ "bird.com" ],
"notLike": [ ".io" ]
}
}
}Each filter group is comprised of the filter keys and comparator keywords. Filter keys must be unique within a grouping, but the same filter key can appear in multiple groupings.
Filter Keys
domainssending_ipsip_poolscampaignssubject_campaignssending_domainsmailbox_providerssubaccountsmailbox_provider_regions
Comparator Keywords
eq- array of exact values to matchlike- array of substrings to match on; values must be at least 3 characters longnotEq- array of exact values to NOT matchnotLike- array of substrings to NOT match on; values must be at least 3 characters long

The aggregations endpoints allow you to get high-level summaries of your data grouped by specific quantifiers such as sending domain or campaign. You can also get specific types of data, such as rejection reason, to better understand your sending.
Use the subaccount field to get metrics about individual subaccounts or set it to 0 to get only the primary account's data.
Lists
Each of the the following endpoints returns a list of their resources for which we have metrics. These help you get an overview of what metrics are available to you.
Industry Benchmarks
The industry benchmarks endpoints allow you to compare your performance to your industry.
