Writing and Publishing Weekly Summary Newsletters

In this tutorial we'll show you how to write and publish weekly summary newsletters automatically with Horizon.

This operation focuses on Horizon workflows and sites, less so than spaces. However, spaces can be helpful to orient and organize various parts of the application. Either way, the goal here is to collect sources, orchestrate and synthesize repeated information from those sources in various formats, posting them with a UI that's appealing, and then dispatching as an email to a list of subscribers.

Step 1: Create a Horizon space to store data

As mentioned, your newsletters need subscribers. Create a table with relevant subscriber information. It can be valuable to store other information regarding your newsletter as well.

Step 2: Design a page corresponding to the weekly format of your newsletter

Your HTML page will be able to be sent via email. Make sure to contain various sections which will represent distinct topics like 'a summary that happened this week', 'article 1', and 'article 2'.

Step 3: Choose your sources as input

The more sources you cultivate, the more interesting transformed content can be. For your newsletter make sure to collect various RSS and X feeds that you will ask an AI to read.

Step 4: Build a workflow or plugin with AI transformations

AI transformations can be used to read and search for specific information, summarize and alter text, and more. The more you ask pointed AI questions and link prompts in multiple stages, the more directed and interesting the resulting articles may become. Create various workflows in order to create artifacts which are unique per newsletter.

Step 5: Trigger workflows to a cadence using Horizon's weekly hook.

The Horizon weekly hooks serve two functions: first, they produce the artifacts (articles, summaries, and titles) that will go into your newsletter. Second, they trigger the actual update or creation from your UI template to produce and store the newsletter. Finally, once the newsletter is created, you can iterate through your list of subscribers in a specific space and trigger an email containing the newsletter HTML.
