.. _mailgun-backend:
Mailgun
=======
Anymail integrates with the `Mailgun <https://mailgun.com>`_
transactional email service from Rackspace, using their
REST API.
Settings
--------
.. rubric:: EMAIL_BACKEND
To use Anymail's Mailgun backend, set:
.. code-block:: python
EMAIL_BACKEND = "anymail.backends.mailgun.MailgunBackend"
in your settings.py. (Watch your capitalization: Mailgun spells their name with a
lowercase "g", so Anymail does too.)
.. setting:: ANYMAIL_MAILGUN_API_KEY
.. rubric:: MAILGUN_API_KEY
Required. Your Mailgun API key:
.. code-block:: python
ANYMAIL = {
...
"MAILGUN_API_KEY": "<your API key>",
}
Anymail will also look for ``MAILGUN_API_KEY`` at the
root of the settings file if neither ``ANYMAIL["MAILGUN_API_KEY"]``
nor ``ANYMAIL_MAILGUN_API_KEY`` is set.
.. setting:: ANYMAIL_MAILGUN_API_URL
.. rubric:: MAILGUN_API_URL
The base url for calling the Mailgun API. It does not include
the sender domain. (Anymail :ref:`figures this out <mailgun-sender-domain>`
for you.)
The default is ``MAILGUN_API_URL = "https://api.mailgun.net/v3"``
(It's unlikely you would need to change this.)
.. _mailgun-sender-domain:
Email sender domain
-------------------
Mailgun's API requires a sender domain `in the API url <base-url>`_.
By default, Anymail will use the domain of each email's from address
as the domain for the Mailgun API.
If you need to override this default, you can use Anymail's
:attr:`esp_extra` dict, either on an individual message:
.. code-block:: python
message = EmailMessage(from_email="sales@europe.example.com", ...)
message.esp_extra = {"sender_domain": "example.com"}
... or as a global :ref:`send default <send-defaults>` setting that applies
to all messages:
.. code-block:: python
ANYMAIL = {
...
"MAILGUN_SEND_DEFAULTS": {
"esp_extra": {"sender_domain": "example.com"}
}
}
.. _base-url: https://documentation.mailgun.com/api-intro.html#base-url
.. _mailgun-esp-extra:
exp_extra support
-----------------
Anymail's Mailgun backend will pass all :attr:`~anymail.message.AnymailMessage.esp_extra`
values directly to Mailgun. You can use any of the (non-file) parameters listed in the
`Mailgun sending docs`_. Example:
.. code-block:: python
message = AnymailMessage(...)
message.esp_extra = {
'o:testmode': 'yes', # use Mailgun's test mode
}

.. _mailgun-webhooks:
Status tracking webhooks
------------------------
If you are using Anymail's normalized :ref:`status tracking <event-tracking>`, enter
the url in your `Mailgun dashboard`_ on the "Webhooks" tab. Mailgun allows you to enter
a different URL for each event type: just enter this same Anymail tracking URL
for all events you want to receive:
:samp:`https://{random}:{random}@{yoursite.example.com}/anymail/mailgun/tracking/`
* *random:random* is an :setting:`ANYMAIL_WEBHOOK_AUTHORIZATION` shared secret
* *yoursite.example.com* is your Django site
If you use multiple Mailgun sending domains, you'll need to enter the webhook
URLs for each of them, using the selector on the left side of Mailgun's dashboard.
Mailgun implements a limited form of webhook signing, and Anymail will verify
these signatures (based on your :setting:`MAILGUN_API_KEY <ANYMAIL_MAILGUN_API_KEY>`
Anymail setting).
Mailgun will report these Anymail :attr:`~anymail.signals.AnymailTrackingEvent.event_type`\s:
delivered, rejected, bounced, complained, unsubscribed, opened, clicked.
The event's :attr:`~anymail.signals.AnymailTrackingEvent.esp_event` field will be
a Django :class:`~django.http.QueryDict` object of `Mailgun event fields`_.
