Djrill, for Mandrill Djrill: Mandrill for Django
==================== ===========================
Djrill integrates the `Mandrill <http://mandrill.com>`_ transactional
email service into Django.
In general, Djrill "just works" with Django's built-in
`django.core.mail <https://docs.djangoproject.com/en/dev/topics/email/>`_
functions. It supports:
* HTML email, attachments, extra headers, and other basic email functionality
* Mandrill-specific extensions like tags, metadata, tracking, and MailChimp templates
* An optional Django admin interface

:target: https://travis-ci.org/brack3t/Djrill :target: https://travis-ci.org/brack3t/Djrill
Djrill is an email backend for Django users who want to take advantage of the Djrill is tested with Django 1.3 and later (including Python 3 support with Django 1.5).
Mandrill_ transactional email service from MailChimp_. It is made available under the BSD license.
In general, Djrill "just works" with Django's built-in `django.core.mail`_
package. You can also take advantage of Mandrill-specific features like tags,
metadata, and tracking.
An optional Django admin interface is included. The admin interface allows you to:
* Check the status of your Mandrill API connection.
* See stats on email senders, tags and urls.
Djrill is made available under the BSD license.
Installation
------------
Install from PyPI::
pip install djrill
The only dependency other than Django is the requests_ library from Kenneth
Reitz. (If you do not install Djrill using pip or setuptools, you will also
need to ``pip install requests``.)
Configuration
-------------
In ``settings.py``:
1. Add ``djrill`` to your ``INSTALLED_APPS``:
.. code:: python
INSTALLED_APPS = (
...
"djrill"
)
2. Add the following line, substituting your own ``MANDRILL_API_KEY``:
.. code:: python
MANDRILL_API_KEY = "brack3t-is-awesome"
3. Override your existing email backend with the following line:
.. code:: python
EMAIL_BACKEND = "djrill.mail.backends.djrill.DjrillBackend"
4. (optional) If you want to be able to add senders through Django's admin or
view stats about your messages, do the following in your base ``urls.py``:
.. code:: python
...
from django.contrib import admin
from djrill import DjrillAdminSite
admin.site = DjrillAdminSite()
admin.autodiscover()
...
urlpatterns = patterns('',
...
url(r'^admin/', include(admin.site.urls)),
)
Usage
-----
Since you are replacing the global ``EMAIL_BACKEND``, **all** emails are sent
through Mandrill's service. (To selectively use Mandrill for some messages, see
`Using Multiple Email Backends`_ below.)
In general, Djrill "just works" with Django's built-in `django.core.mail`_
package, including ``send_mail``, ``send_mass_mail``, ``EmailMessage`` and
``EmailMultiAlternatives``.
You can also take advantage of Mandrill-specific features like tags, metadata,
and tracking by creating a Django EmailMessage_ (or for HTML,
EmailMultiAlternatives_) object and setting Mandrill-specific
properties on it before calling its ``send`` method. (See
`Mandrill Message Options`_ below.)
Example, sending HTML email with Mandrill tags and metadata:
.. code:: python
from django.core.mail import EmailMultiAlternatives
msg = EmailMultiAlternatives(
subject="Djrill Message",
body="This is the text version of your email",
from_email="Djrill Sender <djrill@example.com>",
to=["Djrill Receiver <djrill.receiver@example.com>", "another.person@example.com"],
headers={'Reply-To': "Service <support@example.com>"} # optional extra headers
)
msg.attach_alternative("<p>This is the HTML version of your email</p>", "text/html")
# Optional Mandrill-specific extensions (see full list below):
msg.tags = ["one tag", "two tag", "red tag", "blue tag"]
msg.metadata = {'user_id': "8675309"}
# Send it:
msg.send()
If the email tries to use features that aren't supported by Mandrill, the send
call will raise a ``djrill.NotSupportedByMandrillError`` exception (a subclass
of ValueError).
If the Mandrill API fails or returns an error response, the send call will
raise a ``djrill.MandrillAPIError`` exception (a subclass of
requests.HTTPError).
Django EmailMessage Support
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Djrill supports most of the functionality of Django's `EmailMessage`_ and
`EmailMultiAlternatives`_ classes. Some notes and limitations:
* **Display Names:** All email addresses (from, to, cc) can be simple
("email@example.com") or can include a display name
("Real Name <email@example.com>").
* **From Address:** The ``from_email`` must be in one of the approved sending
domains in your Mandrill account.
* **CC Recipients:** Djrill treats all "cc" recipients as if they were
additional "to" addresses. (Mandrill does not distinguish "cc" from "to".)
Note that you will also need to set ``preserve_recipients`` True if you want
each recipient to see the other recipients listed in the email headers.
* **BCC Recipients:** Mandrill does not permit more than one "bcc" address.
Djrill raises ``djrill.NotSupportedByMandrillError`` if you attempt to send a
message with multiple bcc's. (Mandrill's bcc option seems intended primarily
for logging. To send a single message to multiple recipients without exposing
their email addresses to each other, simply include them all in the "to" list
and leave ``preserve_recipients`` set to False.)
* **Attachments:** Djrill includes a message's attachments. Also, if an image
attachment has a Content-ID header, Djrill will tell Mandrill to treat that
as an embedded image rather than an ordinary attachment. (For an example,
see ``test_embedded_images`` in tests/test_mandrill_send.py.)
* **Headers:** Djrill accepts additional headers, but only ``Reply-To`` and
``X-*`` (since that is all that Mandrill accepts). Any other extra headers
will raise ``djrill.NotSupportedByMandrillError`` when you attempt to send the
message.
* **Alternative Parts:** Djrill requires that if you ``attach_alternative`` to a
message, there must be only one alternative part, and it must be text/html.
Otherwise, Djrill will raise ``djrill.NotSupportedByMandrillError`` when you
attempt to send the message. (Mandrill doesn't support sending multiple html
alternative parts, or any non-html alternatives.)
Mandrill Message Options
~~~~~~~~~~~~~~~~~~~~~~~~
Many of the options from the Mandrill `messages/send API`_ ``message``
struct can be set directly on an ``EmailMessage`` (or subclass) object:
* ``track_opens`` - Boolean
* ``track_clicks`` - Boolean (If you want to track clicks in HTML only, not
plaintext mail, you must *not* set this property, and instead just set the
default in your Mandrill account sending options.)
* ``auto_text`` - Boolean
* ``url_strip_qs`` - Boolean
* ``preserve_recipients`` - Boolean
* ``global_merge_vars`` - a dict -- e.g.,
``{ 'company': "ACME", 'offer': "10% off" }``
* ``recipient_merge_vars`` - a dict whose keys are the recipient email addresses
and whose values are dicts of merge vars for each recipient -- e.g.,
``{ 'wiley@example.com': { 'offer': "15% off anvils" } }``
* ``tags`` - a list of strings
* ``google_analytics_domains`` - a list of string domain names
* ``google_analytics_campaign`` - a string or list of strings
* ``metadata`` - a dict
* ``recipient_metadata`` - a dict whose keys are the recipient email addresses,
and whose values are dicts of metadata for each recipient (similar to
``recipient_merge_vars``)
These Mandrill-specific properties work with *any* ``EmailMessage``-derived
object, so you can use them with many other apps that add Django mail
functionality (such as Django template-based messages).
If you have any questions about the python syntax for any of these properties,
see ``DjrillMandrillFeatureTests`` in tests/test_mandrill_send.py for examples.
Mandrill Templates
~~~~~~~~~~~~~~~~~~
To use a Mandrill (MailChimp) template, set a ``template_name`` and (optionally)
``template_content`` on your ``EmailMessage`` object:
.. code:: python
msg = EmailMessage(subject="Shipped!", from_email="store@example.com",
to=["customer@example.com", "accounting@example.com"])
msg.template_name = "SHIPPING_NOTICE" # A Mandrill template name
msg.template_content = { # Content blocks to fill in
'TRACKING_BLOCK': "<a href='.../\*\|TRACKINGNO\|\*'>track it</a>" }
msg.global_merge_vars = { # Merge tags in your template
'ORDERNO': "12345", 'TRACKINGNO': "1Z987" }
msg.merge_vars = { # Per-recipient merge tags
'accounting@example.com': { 'NAME': "Pat" },
'customer@example.com': { 'NAME': "Kim" } }
msg.send()
If template_name is set, Djrill will use Mandrill's `messages/send-template API`_,
rather than messages/send. All of the other options listed above can be used.
(This is for *MailChimp* templates stored in your Mandrill account. If you
want to use a *Django* template, you can use Django's render_to_string_ template
shortcut to build the body and html, and send using EmailMultiAlternatives as
in the earlier examples.)
Using Multiple Email Backends
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can use Django mail's optional ``connection`` argument to send some mail
through Mandrill and others through a different system. This can be useful to
send customer emails with Mandrill, but admin emails directly through an SMTP
server. Example:
.. code:: python
from django.core.mail import send_mail, get_connection
# send_mail connection defaults to the settings EMAIL_BACKEND, which
# we've set to DjrillBackend. This will be sent using Mandrill:
send_mail("Subject", "Body", "support@example.com", ["user@example.com"])
# Get a connection to an SMTP backend, and send using that instead:
smtp_backend = get_connection('django.core.mail.backends.smtp.EmailBackend')
send_mail("Subject", "Body", "admin@example.com", ["alert@example.com"],
connection=smtp_backend)
You can supply a different connection to Django's `django.core.mail`_
``send_mail`` and ``send_mass_mail`` helpers, and in the constructor for an
EmailMessage_ or EmailMultiAlternatives_.
Testing
-------
Djrill is tested against Django 1.3 and 1.4 on Python 2.6 and 2.7, and
Django 1.5RC on Python 2.7 and 3.2.
(It may also work with Django 1.2 and Python 2.5, if you use an older
version of requests compatible with that code.)
.. image:: https://secure.travis-ci.org/brack3t/Djrill.png?branch=master
:target: https://travis-ci.org/brack3t/Djrill
The included tests verify that Djrill constructs the expected Mandrill API
calls, without actually calling Mandrill or sending any email. So the tests
don't require a Mandrill API key, but they *do* require mock_
(``pip install mock``). To run the tests, either::
python -Wall setup.py test
or::
python -Wall runtests.py
Contributing
------------
Djrill is maintained by its users -- it's not managed by the folks at MailChimp.
Pull requests are always welcome to improve support for Mandrill and Django
features.
Please include test cases with pull requests. (And by submitting a pull request,
you're agreeing to release your changes under under the same BSD license as the
rest of this project.)
Release Notes
-------------
Version 0.3.0:
* Attachments are now supported
* Mandrill templates are now supported
* A bcc address is now passed to Mandrill as bcc, rather than being lumped in
with the "to" recipients. Multiple bcc recipients will now raise an exception,
as Mandrill only allows one.
* Python 3 support (with Django 1.5)
* Exceptions should be more useful: ``djrill.NotSupportedByMandrillError``
replaces generic ValueError; ``djrill.MandrillAPIError`` replaces
DjrillBackendHTTPError, and is now derived from requests.HTTPError. (New
exceptions are backwards compatible with old ones for existing code.)
Version 0.2.0:
* ``MANDRILL_API_URL`` is no longer required in settings.py
* Earlier versions of Djrill required use of a ``DjrillMessage`` class to
specify Mandrill-specific options. This is no longer needed -- Mandrill
options can now be set directly on a Django EmailMessage_ object or any
subclass. (Existing code can continue to use ``DjrillMessage``.)

will send through Mandrill::
from django.core.mail import send_mail
send_mail("It works!", "This will get sent through Mandrill",
"Djrill Sender <djrill@example.com>", ["to@example.com"])
You could send an HTML message, complete with custom Mandrill tags and metadata::
from django.core.mail import EmailMultiAlternatives
msg = EmailMultiAlternatives(
subject="Djrill Message",
body="This is the text email body",
from_email="Djrill Sender <djrill@example.com>",
to=["Recipient One <someone@example.com>", "another.person@example.com"],

Installation
============
It's easiest to install Djrill from `PyPI <https://pypi.python.org/pypi/djrill>`_:
.. code-block:: console
$ pip install djrill
If you decide to install Djrill some other way, you'll also need to install its
one dependency (other than Django, of course): the `requests <http://docs.python-requests.org>`_
library from Kenneth Reitz.
Configuration
-------------
In your project's :file:`settings.py`:
1. Add :mod:`djrill` to your :setting:`INSTALLED_APPS`::
INSTALLED_APPS = (
...
"djrill"
)
2. Add the following line, substituting your own :setting:`MANDRILL_API_KEY`::
MANDRILL_API_KEY = "brack3t-is-awesome"
3. Override your existing :setting:`EMAIL_BACKEND` with the following line::
EMAIL_BACKEND = "djrill.mail.backends.djrill.DjrillBackend"
Admin (Optional)
----------------
Djrill includes an optional Django admin interface, which allows you to:
* Check the status of your Mandrill API connection
* See stats on email senders, tags and urls
If you want to enable the Djrill admin interface, edit your base :file:`urls.py`:

Mixing Email Backends
=====================
Since you are replacing Django's global :setting:`EMAIL_BACKEND`, by default
Djrill will handle all outgoing mail, sending everything through Mandrill.
You can use Django mail's optional :func:`connection <django.core.mail.get_connection>`
argument to send some mail through Mandrill and others through a different system.
This could be useful, for example, to deliver customer emails with Mandrill,
but send admin emails directly through an SMTP server:
.. code-block:: python
:emphasize-lines: 8,10
from django.core.mail import send_mail, get_connection
# send_mail connection defaults to the settings EMAIL_BACKEND, which
# we've set to DjrillBackend. This will be sent using Mandrill:
send_mail("Thanks", "We sent your order", "sales@example.com", ["customer@example.com"])
# Get a connection to an SMTP backend, and send using that instead:
smtp_backend = get_connection('django.core.mail.backends.smtp.EmailBackend')
send_mail("Uh-Oh", "Need your attention", "admin@example.com", ["alert@example.com"],
connection=smtp_backend)
You can supply a different connection to Django's
:func:`~django.core.mail.send_mail` and :func:`~django.core.mail.send_mass_mail` helpers,

Sending Mail
============
Djrill handles **all** outgoing email sent through Django's standard
:mod:`django.core.mail` package, including :func:`~django.core.mail.send_mail`,
:func:`~django.core.mail.send_mass_mail`, the :class:`~django.core.mail.EmailMessage` class,
and even :func:`~django.core.mail.mail_admins`.
If you'd like to selectively send only some messages through Mandrill,
there is a way to :ref:`use multiple email backends <multiple-backends>`.

Django Email Support
--------------------
Djrill supports most of the functionality of Django's :class:`~django.core.mail.EmailMessage`
and :class:`~django.core.mail.EmailMultiAlternatives` classes.
Some notes and limitations:
**Display Names**
All email addresses (from, to, cc) can be simple
("email\@example.com") or can include a display name
("Real Name <email\@example.com>").
**From Address**
The ``from_email`` must be in one of the approved sending
domains in your Mandrill account, or Mandrill will refuse to send the message.
**CC Recipients**
Djrill treats all "cc" recipients as if they were
additional "to" addresses. (Mandrill does not distinguish "cc" from "to".)
.. note::
By default, Mandrill hides all recipients from each other. If you want the
headers to list everyone who was sent the message, you'll also need to set the
Mandrill option :attr:`preserve_recipients` to `!True`
**BCC Recipients**
Mandrill does not permit more than one "bcc" address.
Djrill raises :exc:`~djrill.NotSupportedByMandrillError` if you attempt to send a
message with multiple bcc's.
(Mandrill's bcc option seems intended primarily
for logging. To send a single message to multiple recipients without exposing
their email addresses to each other, simply include them all in the "to" list
and leave Mandrill's :attr:`preserve_recipients` set to `!False`.)
.. versionadded:: 0.3
Previously "bcc" was treated as "cc"
.. _sending-html:
**HTML/Alternative Parts**
To include an HTML version of a message, use
:meth:`~django.core.mail.EmailMultiAlternatives.attach_alternative`:
.. code-block:: python
from django.core.mail import EmailMultiAlternatives
msg = EmailMultiAlternatives("Subject", "text body",
"from@example.com", ["to@example.com"])
msg.attach_alternative("<html>html body</html>", "text/html")
Djrill allows a maximum of one
:meth:`~django.core.mail.EmailMultiAlternatives.attach_alternative`
on a message, and it must be ``mimetype="text/html"``.
Otherwise, Djrill will raise :exc:`~djrill.NotSupportedByMandrillError` when you
attempt to send the message. (Mandrill doesn't support sending multiple html
alternative parts, or any non-html alternatives.)
.. _sending-attachments:
**Attachments**
Djrill will send a message's attachments. (Note that Mandrill may impose limits
on size and type of attachments.)
Also, if an image attachment has a Content-ID header, Djrill will tell Mandrill
to treat that as an embedded image rather than an ordinary attachment.
(For an example, see :meth:`~DjrillBackendTests.test_embedded_images`
in :file:`tests/test_mandrill_send.py`.)
.. versionadded:: 0.3
Attachments
.. versionchanged:: 0.4
Special handling for embedded images
**Headers**
Djrill accepts additional headers, but only ``Reply-To`` and
``X-*`` (since that is all that Mandrill accepts). Any other extra headers
will raise :exc:`~djrill.NotSupportedByMandrillError` when you attempt to send the
message.

Mandrill-Specific Options
-------------------------
Most of the options from the Mandrill
`messages/send API <https://mandrillapp.com/api/docs/messages.html#method=send>`_
`message` struct can be set directly on an :class:`~django.core.mail.EmailMessage`
(or subclass) object:
.. attribute:: track_opens
``Boolean``: whether Mandrill should enable open-tracking for this message.
Default from your Mandrill account settings. ::
message.track_opens = True
.. attribute:: track_clicks
``Boolean``: whether Mandrill should enable click-tracking for this message.
Default from your Mandrill account settings.
.. note::
Mandrill has an option to track clicks in HTML email but not plaintext, but
it's *only* available in your Mandrill account settings. If you want to use that
option, set it at Mandrill, and *don't* set the ``track_clicks`` attribute here.
.. attribute:: auto_text
``Boolean``: whether Mandrill should automatically generate a text body from the HTML.
Default from your Mandrill account settings.
.. attribute:: url_strip_qs
``Boolean``: whether Mandrill should ignore any query parameters when aggregating
URL tracking data. Default from your Mandrill account settings.
.. attribute:: preserve_recipients
``Boolean``: whether Mandrill should include all recipients in the "to" message header.
Default from your Mandrill account settings.
.. attribute:: global_merge_vars
``dict``: merge variables to use for all recipients (most useful with :ref:`mandrill-templates`). ::
message.global_merge_vars = {'company': "ACME", 'offer': "10% off"}
.. attribute:: recipient_merge_vars
``dict``: per-recipient merge variables (most useful with :ref:`mandrill-templates`). The keys
in the dict are the recipient email addresses, and the values are dicts of merge vars for
each recipient::
message.recipient_merge_vars = {
'wiley@example.com': {'offer': "15% off anvils"},
'rr@example.com': {'offer': "instant tunnel paint"}
}
.. attribute:: tags
``list`` of ``str``: tags to apply to the message, for filtering reports in the Mandrill
dashboard. (Note that Mandrill prohibits tags longer than 50 characters or starting with
underscores.) ::
message.tags = ["Order Confirmation", "Test Variant A"]
.. attribute:: google_analytics_domains
``list`` of ``str``: domain names for links where Mandrill should add Google Analytics
tracking parameters. ::
message.google_analytics_domains = ["example.com"]
.. attribute:: google_analytics_campaign
``str`` or ``list`` of ``str``: the utm_campaign tracking parameter to attach to links
when adding Google Analytics tracking. (Mandrill defaults to the message's from_email as
the campaign name.)
.. attribute:: metadata
``dict``: metadata values Mandrill should store with the message for later search and
retrieval. ::
message.metadata = {'customer': customer.id, 'order': order.reference_number}
.. attribute:: recipient_metadata
``dict``: per-recipient metadata values. Keys are the recipient email addresses,
and values are dicts of metadata for each recipient (similar to
:attr:`recipient_merge_vars`)
These Mandrill-specific properties work with *any*
:class:`~django.core.mail.EmailMessage`-derived object, so you can use them with
many other apps that add Django mail functionality.
If you have questions about the python syntax for any of these properties,
see :class:`DjrillMandrillFeatureTests` in :file:`tests/test_mandrill_send.py` for examples.
.. _djrill-exceptions:
Exceptions
----------
.. versionadded:: 0.3
Djrill-specific exceptions
.. exception:: djrill.NotSupportedByMandrillError
If the email tries to use features that aren't supported by Mandrill, the send
call will raise a :exc:`~!djrill.NotSupportedByMandrillError` exception (a subclass
of :exc:`ValueError`).
.. exception:: djrill.MandrillAPIError
If the Mandrill API fails or returns an error response, the send call will
raise a :exc:`~!djrill.MandrillAPIError` exception (a subclass of :exc:`requests.HTTPError`).
The exception's :attr:`status_code` and :attr:`response` attributes may
help explain what went wrong.

Sending Template Mail
=====================
.. _mandrill-templates:
Mandrill Templates
------------------
.. versionadded:: 0.3
Mandrill template support
To use a *Mandrill* (MailChimp) template stored in your Mandrill account,
set a :attr:`template_name` and (optionally) :attr:`template_content`
on your :class:`~django.core.mail.EmailMessage` object::
from django.core.mail import EmailMessage
msg = EmailMessage(subject="Shipped!", from_email="store@example.com",
to=["customer@example.com", "accounting@example.com"])
msg.template_name = "SHIPPING_NOTICE" # A Mandrill template name
msg.template_content = { # Content blocks to fill in
'TRACKING_BLOCK': "<a href='.../*|TRACKINGNO|*'>track it</a>"
}
msg.global_merge_vars = { # Merge tags in your template
'ORDERNO': "12345", 'TRACKINGNO': "1Z987"
}
msg.merge_vars = { # Per-recipient merge tags
'accounting@example.com': {'NAME': "Pat"},
'customer@example.com': {'NAME': "Kim"}
}
msg.send()
If :attr:`template_name` is set, Djrill will use Mandrill's
`messages/send-template API <https://mandrillapp.com/api/docs/messages.html#method=send-template>`_,
and will ignore any `body` text set on the `EmailMessage`.
All of Djrill's other :ref:`Mandrill-specific options <mandrill-send-support>`
can be used with templates.
.. _django-templates:
Django Templates
----------------
To compose email using *Django* templates, you can use Django's
:func:`~django.template.loaders.django.template.loader.render_to_string`
template shortcut to build the body and html.
Example that builds an email from the templates ``message_subject.txt``,
``message_body.txt`` and ``message_body.html``::
from django.core.mail import EmailMultiAlternatives
from django.template import Context
from django.template.loader import render_to_string
template_data = {
'ORDERNO': "12345", 'TRACKINGNO': "1Z987"
}
plaintext_context = Context(autoescape=False) # HTML escaping not appropriate in plaintext
subject = render_to_string("message_subject.txt", template_data, plaintext_context)
text_body = render_to_string("message_body.txt", template_data, plaintext_context)
html_body = render_to_string("message_body.html", template_data)
msg = EmailMessage(subject=subject, from_email="store@example.com",
to=["customer@example.com"], body=text_body)
msg.attach_alternative(html_body, "text/html")
msg.send()
