Email-to-RSS

Convert email newsletters into a private RSS feed using Cloudflare Workers + ForwardEmail.

This project is self-hosted, uses your own domain, and keeps your data in your own Cloudflare account.

Why this exists

Many newsletters only support email delivery. RSS readers offer a better reading experience, but getting email-only newsletters into RSS usually means relying on shared third-party infrastructure.

Email-to-RSS keeps the same workflow while avoiding shared domains and shared data stores.

Features

• One-click feed creation from an admin dashboard
• Bulk feed/email deletion from the admin dashboard (safe checkbox-based flow)
• Inline double-confirm delete interactions with toast feedback in the admin dashboard
• Resizable + sortable table columns in the admin dashboard (Table view)
• Unique newsletter addresses per feed (for example apple.mountain.42@yourdomain.com)
• ForwardEmail webhook ingestion with source-IP verification
• Optional per-feed sender allowlist (email@domain.com or domain.com)
• RSS generation on demand (/rss/:feedId)
• Cloudflare KV storage for feed config + email metadata/content
• Password-protected admin UI
• Fully self-hosted on your Cloudflare account

Architecture

1. ForwardEmail forwards inbound messages to https://yourdomain.com/api/inbound.
2. The Worker validates the request source against ForwardEmail MX IP ranges.
3. The Worker parses and stores incoming content in KV.
4. https://yourdomain.com/rss/:feedId renders RSS from stored items.
5. /admin provides feed management and email deletion.

Main routes:

• src/routes/inbound.ts: webhook ingestion
• src/routes/rss.ts: RSS rendering
• src/routes/admin.ts: admin UI + feed CRUD

Requirements

• Node.js 20+
• A Cloudflare account
• A domain managed in Cloudflare DNS
• A ForwardEmail account

Setup

1. Clone this repository.
2. Authenticate Wrangler:

   npx wrangler login

3. Run setup:

   bash setup.sh

setup.sh will:

• install npm dependencies
• verify Cloudflare auth (wrangler whoami)
• create KV namespaces (EMAIL_STORAGE + preview)
• set the ADMIN_PASSWORD secret in production
• generate wrangler.toml from wrangler-example.toml
• stamp compatibility_date to the current date

4. Configure ForwardEmail DNS records in Cloudflare:

Type	Name	Content	Notes
MX	@	mx1.forwardemail.net	Priority 10, DNS only
MX	@	mx2.forwardemail.net	Priority 10, DNS only
TXT	@	"forward-email=https://yourdomain.com/api/inbound"	webhook target
TXT	@	"v=spf1 include:spf.forwardemail.net -all"	SPF

5. Deploy:

   npm run deploy

6. Open https://yourdomain.com/admin and sign in.

Development

npm install
npm run dev
npm test
npm run build

Configuration notes

• wrangler-example.toml is the template; wrangler.toml is generated locally.
• Keep compatibility_date fresh when doing runtime upgrades.
• ADMIN_PASSWORD is a Cloudflare Worker secret, not a plain env var in config.

Security notes

• Inbound webhook access is IP-restricted to ForwardEmail MX sources.
• Admin auth uses a signed, HttpOnly, Secure, SameSite=Strict cookie.
• Admin responses are no-store to avoid cache leakage.
• For high-value feeds, set Allowed senders so only known sender addresses/domains are accepted.
• You should use a strong admin password and rotate periodically.

Spam cleanup runbook

UI-first cleanup

1. Open /admin.
2. Switch to Table view.
3. Use the search box to filter obvious spam feeds.
   • Long titles/URLs are truncated; hover to see the full value. Click to copy.
   • Drag the column separators to resize; click headers to sort (double-click a separator to reset width).
4. Use Select Results to select the filtered rows, then click Delete Selected.
   • Bulk deletes run in small batches so the UI stays responsive. Keep the tab open until it finishes.
5. For legitimate feeds that got spam emails, open Emails, filter by subject, then Select Results and Delete Selected.

Upgrading dependencies

To refresh dependencies to latest:

npm outdated
npm install
npm test
npm run build

Then update compatibility_date and redeploy.
