 # Email-to-RSS
 
-A modern service that turns email newsletters into RSS feeds, built with Cloudflare Workers. This service provides unique email addresses per feed, a front-end admin panel, and long-term storage of newsletters.
+A modern service that turns email newsletters into RSS feeds, built with Cloudflare Workers and ForwardEmail.net. This service provides unique email addresses per feed, a front-end admin panel, and long-term storage of newsletters.
+
+## Why Email to RSS?
+
+I love consolidating my newsletters into a centralized reading app like [Reeder](https://reederapp.com). They make for a better reading experience and prevents my email inbox from getting clogged with newsletters. However, Reeder requires RSS support and many email newsletters don't support native RSS feeds.
+
+There are some free services online that do the same thing (e.g. [kill-the-newsletter.com](kill-the-newsletter.com)), but there are several downsides to this approach:
+
+- **No long-term retention**: old RSS posts are deleted to save space.
+- **Risk of blocklisting**: being forced to use the same domain (@kill-the-newsletter.com) as everyone else increases the likelihood that an email newsletter can blocklist you from signing up.
+- **Self-hosting is non-trivial**: Kill The Newsletter is also [open source](https://github.com/leafac/kill-the-newsletter), but the self-hosting steps seem neither straightforward nor does it focus on exclusively leveraging free services.
+
+On the other hand, while Email-to-RSS isn't necessarily a one-click-deploy solution, it works just as well, is customized to your domain, and is completely free (except for the custom domain itself)!

+
+## Setup
+
+1. Buy your custom domain. You can buy it directly from Cloudflare for convenience. If purchased elsewhere, add the domain to your Cloudflare account to manage the DNS there.
+2. Clone this repository.
+3. Open your command line in the cloned repo folder and run: `bash setup.sh` – this will install dependencies and set up the Cloudflare Worker/KV with your admin password.
+4. Set up your ForwardEmail.net account and configure it to forward to Cloudflare (replace `yourdomain.com` with your custom domain):
+
+   1. Sign up for a free account using any email (doesn't necessarily have to be the one used for the newsletter).
+   2. Add your custom domain.
+   3. To verify your domain, add the following DNS records to your Cloudflare DNS configuration:
+
+      | Type | Name | Content                                            | TTL  | Proxy Status | Notes                                    |
+      | ---- | ---- | -------------------------------------------------- | ---- | ------------ | ---------------------------------------- |
+      | MX   | @    | mx1.forwardemail.net                               | Auto | DNS only     | Set Priority to 10.                      |
+      | MX   | @    | mx2.forwardemail.net                               | Auto | DNS only     | Set Priority to 10.                      |
+      | TXT  | @    | "forward-email=https://yourdomain.com/api/inbound" | Auto | DNS only     | This forwards your emails to the webhook |
+      | TXT  | @    | "v=spf1 include:spf.forwardemail.net -all"         | Auto | DNS only     | Email security                           |
+
+5. Deploy with `npm run deploy`.
+6. Go to yourdomain.com to open up the admin panel and log in!
+
+Tip: If you're unsure about any of these steps, ask ChatGPT or Cursor to guide you through them.
 
 ## Architecture
 
 ### Email Flow
 
-1. A newsletter arrives at `apple.mountain.42@yourdomain.com` (feed ID format: noun1.noun2.XX)
-2. ForwardEmail.net forwards it to your Cloudflare Worker
-3. The Worker parses the email, extracts content, and stores it in KV
-4. The RSS feed is updated with the new content
+1. A newsletter email arrives at `apple.mountain.42@yourdomain.com` (feed ID format: noun1.noun2.XY).
+2. ForwardEmail.net forwards it to your Cloudflare Worker endpoint via webhook.
+3. The Worker validates the request is from ForwardEmail.net based on IP address.
+4. The email is parsed, content extracted, and stored in Cloudflare KV.
+5. Feed metadata is updated to include the new email.
+6. The RSS feed endpoint dynamically generates the feed from stored emails.

 ## Feed ID System

+The system generates memorable, user-friendly feed IDs in the format `noun1.noun2.XY` where:
