Postmark
|
|
========
|
|
|
|
Anymail integrates with the `Postmark`_ transactional email service,
|
|
using their `HTTP email API`_.
|
|
|
|
.. _Postmark: https://postmarkapp.com/
|
|
.. _HTTP email API: http://developer.postmarkapp.com/developer-api-email.html
|
|
|
|
|
|
Settings
|
|
--------
|
|
|
|
.. rubric:: EMAIL_BACKEND
|
|
|
|
To use Anymail's Postmark backend, set:
|
|
|
|
.. code-block:: python
|
|
|
|
EMAIL_BACKEND = "anymail.backends.postmark.PostmarkBackend"
|
|
|
|
in your settings.py. (Watch your capitalization: Postmark spells their name with a
|
|
lowercase "m", so Anymail does too.)
|
|
|
|
|
|
.. setting:: ANYMAIL_POSTMARK_SERVER_TOKEN
|
|
|
|
.. rubric:: POSTMARK_SERVER_TOKEN
|
|
|
|
Required. A Postmark server token.
|
|
|
|
.. code-block:: python
|
|
|
|
ANYMAIL = {
|
|
...
|
|
"POSTMARK_SERVER_TOKEN": "<your server token>",
|
|
}
|
|
|
|
Anymail will also look for ``POSTMARK_SERVER_TOKEN`` at the
|
|
root of the settings file if neither ``ANYMAIL["POSTMARK_SERVER_TOKEN"]``
|
|
nor ``ANYMAIL_POSTMARK_SERVER_TOKEN`` is set.
|
|
|
|
You can override the server token for an individual message in
|
|
its :ref:`esp_extra <postmark-esp-extra>`.
|
|
|
|
|
|
.. setting:: ANYMAIL_POSTMARK_API_URL
|
|
|
|
.. rubric:: POSTMARK_API_URL
|
|
|
|
The base url for calling the Postmark API.
|
|
|
|
The default is ``POSTMARK_API_URL = "https://api.postmarkapp.com/"``
|
|
(It's unlikely you would need to change this.)
|
|
|
|
|
|
.. _postmark-esp-extra:
|
|
|
|
esp_extra support
|
|
-----------------
|
|
|
|
To use Postmark features not directly supported by Anymail, you can
|
|
set a message's :attr:`~anymail.message.AnymailMessage.esp_extra` to
|
|
a `dict` that will be merged into the json sent to Postmark's
|
|
`email API`_.
|
|
|
|
Example:
|
|
|
|
.. code-block:: python
|
|
|
|
message.esp_extra = {
|
|
'HypotheticalFuturePostmarkParam': '2022', # merged into send params
|
|
'server_token': '<API server token for just this message>',
|
|
}
|
|
|
|
|
|
(You can also set `"esp_extra"` in Anymail's
|
|
:ref:`global send defaults <send-defaults>` to apply it to all
|
|
messages.)
|
|
|
|

|
|
|
|
|
|
Limitations and quirks
|
|
----------------------
|
|
|
|
Postmark does not support a few tracking and reporting additions offered by other ESPs.
|
|
|
|
Anymail normally raises an :exc:`~anymail.exceptions.AnymailUnsupportedFeature`
|
|
error when you try to send a message using features that Postmark doesn't support
|
|
You can tell Anymail to suppress these errors and send the messages anyway --
|
|
see :ref:`unsupported-features`.
|
|
|
|
**Single tag**
|
|
Postmark allows a maximum of one tag per message. If your message has two or more
|
|
:attr:`~anymail.message.AnymailMessage.tags`, you'll get an
|
|
:exc:`~anymail.exceptions.AnymailUnsupportedFeature` error---or
|
|
if you've enabled :setting:`ANYMAIL_IGNORE_UNSUPPORTED_FEATURES`,
|
|
Anymail will use only the first tag.
|
|
|
|
**No metadata**
|
|
Postmark does not support attaching :attr:`~anymail.message.AnymailMessage.metadata`
|
|
to messages.
|
|
|
|
**No delayed sending**
|
|
Postmark does not support :attr:`~anymail.message.AnymailMessage.send_at`.
|
|
|
|
**Click-tracking**
|
|
Postmark supports `several link-tracking options`_. Anymail treats
|
|
:attr:`~anymail.message.AnymailMessage.track_clicks` as Postmark's
|
|
"HtmlAndText" option when True.
|
|
|
|
If you would prefer Postmark's "HtmlOnly" or "TextOnly" link-tracking, you could
|
|
either set that as a Postmark server-level default (and use `message.track_clicks = False`
|
|
to disable tracking for specific messages), or use something like
|
|
`message.esp_extra = {'TrackLinks': "HtmlOnly"}` to specify a particular option.
|
|

|
|
|
|
|
|
.. _postmark-templates:
|
|
|
|
Batch sending/merge and ESP templates
|
|
-------------------------------------
|
|
|
|
Postmark supports :ref:`ESP stored templates <esp-stored-templates>`
|
|
populated with global merge data for all recipients, but does not
|
|
offer :ref:`batch sending <batch-send>` with per-recipient merge data.
|
|
Anymail's :attr:`~anymail.message.AnymailMessage.merge_data`
|
|
message attribute is not supported with the Postmark backend.
|
|
|
|
To use a Postmark template, set the message's
|
|
:attr:`~anymail.message.AnymailMessage.template_id` to the numeric
|
|
Postmark "TemplateID" and supply the "TemplateModel" using
|
|
the :attr:`~anymail.message.AnymailMessage.merge_global_data`
|
|
message attribute:
|
|
|
|
.. code-block:: python
|
|
|
|
message = EmailMessage(
|
|
...
|
|
subject=None, # use template subject
|
|
to=["alice@example.com"] # single recipient...
|
|
# ...multiple to emails would all get the same message
|
|
# (and would all see each other's emails in the "to" header)
|
|
)
|
|
message.template_id = 80801 # use this Postmark template
|
|
message.merge_global_data = {
|
|
'name': "Alice",
|
|
'order_no': "12345",
|
|
'ship_date': "May 15",
|
|
'items': [
|
|
{'product': "Widget", 'price': "9.99"},
|
|
{'product': "Gadget", 'price': "17.99"},
|
|
],
|
|
}
|
|
|
|
Set the EmailMessage's subject to `None` to use the subject from
|
|
your Postmark template, or supply a subject with the message to override
|
|
the template value.
|
|

|
.. _postmark-webhooks:
|
|
|
|
Status tracking webhooks
|
|
------------------------
|
|
|
|
If you are using Anymail's normalized :ref:`status tracking <event-tracking>`, enter
|
|
the url in your `Postmark account settings`_, under Servers > *your server name* >
|
|
Settings > Outbound > Webhooks. You should enter this same Anymail tracking URL
|
|
for both the "Bounce webhook" and "Opens webhook" (if you want to receive both
|
|
types of events):
|
|
|
|
:samp:`https://{random}:{random}@{yoursite.example.com}/anymail/postmark/tracking/`
|
|
|
|
* *random:random* is an :setting:`ANYMAIL_WEBHOOK_AUTHORIZATION` shared secret
|
|
* *yoursite.example.com* is your Django site
|
|
|
|
Anymail doesn't care about the "include bounce content" and "post only on first open"
|
|
Postmark webhook settings: whether to use them is your choice.
|
|
|
|
If you use multiple Postmark servers, you'll need to repeat entering the webhook
|
|
settings for each of them.
|
|
|
|
Postmark will report these Anymail :attr:`~anymail.signals.AnymailTrackingEvent.event_type`\s:
|
|
rejected, failed, bounced, deferred, autoresponded, opened, complained, unsubscribed, subscribed.
|
|
(Postmark does not support sent, delivered, or clicked events.)
|
|
|
|
The event's :attr:`~anymail.signals.AnymailTrackingEvent.esp_event` field will be
|
|
a `dict` of Postmark `bounce <http://developer.postmarkapp.com/developer-bounce-webhook.html>`_
|
|
or `open <http://developer.postmarkapp.com/developer-open-webhook.html>`_ webhook data.
