Email template:

In template, linked objects can be processed this way by example:

{% if object_types.OBJECT_NAME.instances %}
    <ul><li>{{ object_types.OBJECT_NAME.long_description }}
    <ul>{% for instance in object_types.OBJECT_NAME.instances %}
    <li>{% include 'notification/emails/tracked_link.html' %}</li>
    {% endfor %}</ul>
    </li></ul>
{% endif %}

Messages sent through the django messages framework filtered like this:

{% if messages %}
    {% for message in messages %}
        {% if 'notification' in message.tags %}
            <span class="email-registration-message lvl-{{ message.level }}">{{ message }}</span>
        {% endif %}
    {% endfor %}
{% endif %}
