✉️ Newsletter Signup Test

Signup form hosted on newsletter.golemdrive.com, iframed below to simulate external site embed.

Direct URL: https://newsletter.golemdrive.com/subscription/form

Open form in new tab Scroll to embedded form ↓

Subscribe via public API:

curl -X POST https://newsletter.golemdrive.com/subscription/form \
  -d "email=test@example.com" \
  -d "name=Test User" \
  -d "l=<list-uuid>"

List UUIDs: GET /api/public/lists

How this was tested:

  1. Deployed this HTML to Cloudflare Pages
  2. Iframe loads signup form from tunneled domain (passes through CF Tunnel → Listmonk)
  3. Subscriber submits → double-opt-in email sent via Postal
  4. Confirmation link lands back on /subscription/<uuid>
  5. Subscriber appears in admin at newsletter.golemdrive.com/admin
