An app to fetch a webpage and prepare it for use as an HTML email.

This app fetches the HTML from a URL and "inlines" the styles so the HTML will work in an email.

We use this app to:

• Prepare Tuesday Newsday for sending.

1. This app is written in Javascript, using Express, and it runs on Heroku.
2. It uses a [config object][2] to check that the URL comes from an allowed domain.
