Messages

Send email two ways via our REST API:

  1. Send emails using MIME format using a MIME building library
  2. Submit the individual parts (Text, html, attachments, etc.)

Reminder: You can also send email via SMTP with Mailgun. Please reference the user manual.

Operations

Domains

Domains API manages domains, domain keys and DNS verification.

Operations

Domain Keys

An authentication standard used to prevent email spoofing.

Operations

Domain Tracking

Mailgun offers tracking for clicks, unsubscribes, and opens, with optional HTTPS protocol support on tracking URLs. To enable HTTPS, Mailgun uses Let’s Encrypt with HTTP-01 challenges through your existing tracking CNAME record to issue a TLS certificate. This setup also includes support for HTTP Strict Transport Security (HSTS) for enhanced security.

Operations

DKIM Security

Automatic Sender Security DKIM Key APIs. To enable this feature please see 'Update a domain' API docs.

Operations

Webhooks

Webhooks API manages domain's webhooks. You can create, access and delete webhooks programmatically.

Operations

Metrics

The Mailgun Metrics API provides programmatic access to detailed analytics data about your email sending activity. This API allows you to query, filter, and analyze email performance metrics to gain insights into deliverability, engagement, and overall sending health.

Operations

Data Retention

Mailgun retains metrics data for different durations based on resolution:

  • Hourly: 60 days
  • Daily: 1 year
  • Monthly: Indefinitely

Pagination

For queries that return large result sets, the API uses offset-based pagination with skip and limit request attributes.

  • skip specifies how many items to offset (skip) from the beginning of the result set.
  • limit specifies the maximum number of items to return in a single request.

Defaults and limits:

  • Default page size varies by dimension. Default for time dimension is 1500 items. All other dimensions default to 10 items.
  • Maximum limit is 1500 for the time dimension and 1000 for all other dimensions.

How pagination works:

  • Start with skip=0 and a desired limit (for example, limit=1000).
  • Retrieve the next page by increasing skip by the value of limit:
  • First page: skip=0, limit=1000
  • Second page: skip=1000, limit=1000
  • Third page: skip=2000, limit=1000
  • Continue paging until fewer items than the specified limit are returned.

Additional details:

  • The response includes a pagination object containing the total number of available items.
  • Results can be sorted using the sort parameter, for example time:asc or time:desc. For consistent pagination, use a deterministic sort order.

Rate Limits and Quotas

  • API calls are subject to a rate limit of 500 requests every 10 seconds

Logs

Mailgun keeps track of every inbound and outbound message event and stores this log data. This data can be queried and filtered to provide insights into the health of your email infrastructure.

Bounce Classification

Operations

Tags New

Mailgun allows you to tag your email with unique identifiers. Tags are visible via our analytics tags API endpoint.

Operations

Stats

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

WARNING: This API is deprecated in favor of our Metrics API.

Operations

Tags

Mailgun lets you tag each outgoing message with a custom value. When you access stats on your messages, they will be aggregated by these tags.

WARNING: This API is deprecated in favor of our new Tags API.

Operations

Events

Mailgun keeps track of every inbound and outbound message event and stores this data for at least 3 days.

WARNING: This API is deprecated in favor of our Logs API.

Operations

Alerts

Mailgun allows you to get instant notifications on the sending metrics that matter most, configured specifically for your unique business needs and assets. Route these alerts to the channels your team relies on. Stay on top of sending performance without the need to manually monitor.

Operations

Unsubscribe

Unsubscribe list stores email addresses of recipients who unsubscribed from your mailings by clicking a Mailgun generated unsubscribe link.

Operations

Complaints

Email addresses of recipients who marked your messages as a spam (for ESPs that support FBL).

Operations

Bounces

Bounces - Bounce list stores events of delivery failures due to permanent recipient mailbox errors such as non-existent mailbox. Soft bounces (for example, mailbox is full) and other failures (for example, ESP rejects an email because it thinks it is spam) are not added to the list.

Operations

Allowlist

The allowlist API provides the ability to allowlist specific addresses from being added to bounce list. You can allowlist by domain name (i.e example.com) or by specific address (i.e. alice@example.com). Mailgun doesn’t add an address to bounce list if the address is allowlisted. This API is very useful if you test against your private services and don’t want to constantly clean up bounce lists

Operations

Routes

Define a list of routes to handle incoming emails. When a message matches a route expression, Mailgun can forward it on to your application via HTTP or another email address, or store the message temporarily (3 days) for subsequent retrieval.

Operations

Mailing Lists

Operations

Templates

This API allows you to store predefined templates and use them to send messages using the Sending API.

Operations

IP Pools
