CALC sends email in HTML and plaintext format.

Absolute URLs in the emails are generated via the Django “sites” framework, so you will need to use the CALC admin UI to configure the domain of the singleton Site model to match the host and port of your deployment.

For example, if your CALC instance is at http://localhost:8000/, you should set your Site model’s domain to localhost:8000.

All other email configuration options are defined via environment variables.

Sending test emails

The send_test_html_email management command can be used to send emails and ensure that they’re received and/or render properly, with proper links back to your CALC instance. To use it, just supply the email addresses of the recipients like so:

docker-compose run app python send_test_html_email

You can also send “example” versions of all CALC emails to a single email address like so:

docker-compose run app python send_example_emails

Reading email in development

As part of our Docker setup, we use a container with MailCatcher to make it easy to read the emails sent by the app. You can view it at port 1080: http://localhost:1080.

Iterating on email in development

All emails have “example” versions that can be found on the “Emails” section of the style guide. You can load these in your browser, make changes to the email template, and see the changes in your browser just as you would with any standard Django view.
