Setup

python3 -m pip install emark

# settings.py
INSTALLED_APPS = [
    'emark',
    # ...
]

python3 manage.py migrate

Usage

<!-- myapp/my_message.md -->
# Hello World

Hi {{ user.short_name }}!

# myapp/emails.py
from emark.message import MarkdownEmail

class MyMessage(MarkdownEmail):
    subject = "Hello World"
    template_name = "myapp/my_message.md"

# myapp/views.py
from . import emails

def my_view(request):
    message = emails.MyMessage.to_user(request.user)
    message.send()

Templates

You can use Django's template engine, just like you usually would. You can use translations, template tags, filters, blocks, etc.

You may also have a base template, that you inherit form in your individual emails to provide a consistent salutation and farewell.

<!-- base.md -->
{% load static i18n %}
{% block salutation %}Hi {{ user.short_name }}!{% endblock %}

{% block content %}{% endblock %}

{% block farewell %}
{% blocktrans trimmed %}
Best regards,
{{ site_admin }}
{% endblocktrans %}
{% endblock %}

{% block footer %}
Legal footer.
{% endblock %}

<!-- myapp/email.md -->
{% extends "base.md" %}

{% block content %}
This is the content of the email.
{% endblock %}

Context

The context is passed to the template as a dictionary. Furthermore, you may override the get_context_data method to add additional context variables.

# myapp/emails.py
from emark.message import MarkdownEmail

class MyMessage(MarkdownEmail):
    subject = "Hello World"
    template_name = "myapp/email.md"

    def get_context_data(self):
        context = super().get_context_data()
        context["my_variable"] = "Hello World"
        return context

Tracking

Every MarkdownEmail subclass comes with automatic UTM tracking. UTM parameters are added to all links in the email. Existing UTM params on link that have been explicitly set, are not overridden. The default parameters are:

• utm_source: website
• utm_medium: email
• utm_campaign: {{ EMAIL_CLASS_NAME }}

The global UTM parameters can be overridden via the EMARK_UTM_PARAMS setting, which is a dictionary of parameters:

# settings.py
EMARK_UTM_PARAMS = {
    "utm_source": "website",  # default
    "utm_medium": "email",  # default
}

You may also change the UTM parameters by overriding the get_utm_params or passing a utm_params dictionary to class constructor.

# myapp/emails.py
from emark.message import MarkdownEmail


class MyMessage(MarkdownEmail):
  subject = "Hello World"
  template_name = "myapp/email.md"

  # override the parameters for this email class
  def get_utm_params(self):
    return {
      "utm_source": "myapp",
      "utm_medium": "email",
      "utm_campaign": "my-campaign",
    }


# or alternatively during instantiation
MyMessage(utm_params={"utm_campaign": "my-other-campaign"}).send()
