Hello, this is an app just for the author of this newsletter. If you are the author of this newsletter, please enter the secret password.
The app takes data from a specified Airtable base and renders it as HTML that's ready to be pasted into an input field that accepts HTML, for example, the TinyLetter newsletter editor on the HTML side. But, because this is a sample app - I'll let you in on a secret. The password is test.
See the readme for instructions on how to create your own Airtable-based CMS-lite. The data for this app comes from this example Airtable base, which has the same structure you'll need to create your own.
