Your template can have a plain text version and it’s even recommended to have one. All the Finqu default emails include a plain text version. It is constructed with detecting, rendering and combining the content between the plaintext
tags. For example if you’d have a layout file like this (all the HTML content is removed for clarity):
{% plaintext %}
My email header
{% endplaintext %}
{{ content_for_layout }}
{% plaintext %}
My email footer
{% endplaintext %}
and then you would have your template content like this:
{% plaintext %}
My email content
is here!
{% endplaintext %}
The plain text email would look like this:
My email header
My email content
is here!
My email footer
