Using Cloudflare Turnstile with Email Subscription Form Widget

The Noticeable email subscription form widget helps you collect email addresses from people who want to receive your updates.


Cloudflare Turnstile adds an extra protection layer by blocking bots and fake sign-ups without affecting the user experience.



Creating a Cloudflare Turnstile Widget


  1. Open the Cloudflare dashboard.
  2. Go to Application security → Turnstile.
  3. Click Add widget.
  4. Enter a widget name.
  5. Under Hostname management, add at least two hostnames:
  • The domain or subdomain where the Noticeable widget is embedded (e.g. dashboard.your-company.com).
  • widgets.noticeable.io, which loads Noticeable widget assets. This one is required.
  1. Click Create, then copy the Site key and Secret key.


All three Turnstile modes are supported: managed, non-interactive, and invisible. Pick the one that fits your needs.


Configuring your Noticeable email subscription form widget


  1. Open the Noticeable dashboard.
  2. Click Widgets.
  3. Select your widget to edit it.
  4. In the right panel, ensure Email subscription form is selected under Widget view.
  5. Under Captcha, choose I want to use Cloudflare Turnstile.
  6. Paste your Turnstile Secret key and Site key in the correct fields.
  7. Enjoy!


Be careful not to swap the Turnstile site key and the secret key.
