Mailgun collects many different events and generates event statistics which are available in your Control Panel. This data is also available via an API.

The statistics are calculated in hourly, daily and monthly resolution in UTC timezone.

The following retention policy is applied to the statistics:

  • Hourly stats are preserved for a month.
  • Daily stats are preserved for a year.
  • Monthly stats are stored throughout the lifespan of the domain.
GET /<domain>/stats/total

Returns total stats for a given domain.

Parameter Description
event The type of the event. For a complete list of all events written to the log see the Event Types table below. (Required)
start The starting time. Should be in RFC 2822#page-14 or unix epoch format. Default: 7 days from the current time.
end The ending date. Should be in RFC 2822#page-14 or unix epoch format. Default: current time.
resolution Can be either hour, day or month. Default: day
duration Period of time with resoluton encoded. See Duration for more info. If provided, overwrites the start date.
GET /<domain>/stats

Returns a list of event stats items. Each record represents counts for one event per one day.


This is the legacy API that should not be used.

Parameter Description
limit Maximum number of records to return. (100 by default)
skip Number of records to skip. (0 by default)
event Name of the event to receive the stats for. Note that you can specify this parameter multiple times to fetch stats for several events at the same time (see example below)
start-date The date to receive the stats starting from. Should have ISO8601 format (YYYY-MM-DD).


Duration is a string that represents a period of time with some resolution. It has a format [0-9]+[m,d,h] where

  • h - an hour
  • d - a day
  • m - a month


  • 24h - a period of 24 hours (a day) with hourly resolution
  • 1d - a period of 1 day with daily resolution
  • 2m - a period of 2 months with monthly resolution
