 To add a new snapshot test, follow [the instructions](https://jestjs.io/docs/snapshot-testing) or use [this example](./tests/components/external-link.test.tsx) and then run `npm run test` to automatically create the snapshot file.
 
 To update an existing snapshot, adjust the test case and run `npm run snapshot-update`.

 Every email uses a base [responsive template](https://github.com/leemunroe/responsive-html-email-template) that is located in `material/email-template.html`. Before we send an email, we need to inline the css styles with a tool like [htmlemail.io/inline](https://htmlemail.io/inline/).
 
 Set environment variable `EMAIL_ENABLE=true` to enable the emailing.
