You’ve picked Noptin for its seamless email signup forms and smart automation features.
It’s a favorite among WordPress users who want to collect, grow, and send newsletters and notifications directly from their website, backed by a solid 4.5/5-star rating.
That widespread appeal, however, attracts bots and spam sign-ups.
The good news is you can shut them down effectively with CAPTCHAs, hidden honeypots, smart filters, and more.
In this guide we’ll go through ways to keep your newsletter lists spam-free.
Noptin’s Built In Spam Defenses
Noptin has a double opt-in feature, which requires subscribers to confirm their email address before joining your list.
This simple step automatically weeds out fake signups, cutting spam without extra plugins.
Third-party plugin
Using a third-party plugin like Hizzle Capatcha is a good option for tougher spam protection.
Hizzle captcha also protects forms from several popular plugins, including Noptin.
This means you only use one CAPTCHA plugin for all your site’s forms, reducing the risk of conflict.
Hizzle Captcha supports the following CAPTCHA:
- Google recaptcha V2 (“I’m not a robot” Checkbox)
- Google reCAPTCHA V2 (Invisible)
- Score-based reCAPTCHA V3
- Cloudflare Turnstile (Our top pic)
Hizzle Captcha And Noptin Setup
Prerequisites
You need to have Noptin installed and activated.
Install Hizzle Captcha
Log into your WordPress admin dashboard. Go to Plugins > Add New, search for “Hizzle CAPTCHA,” then hit Install Now and Activate.
Configure Hizzle for Noptin
- Navigate to capture > settings.
- Select your capture type, I highly recommend Cloudflare Turnistile for its privacy focus (no cookies or tracking) and seamless user experience.
- Enter your site key and secret key. For Turnstile, grab them from your Cloudflare dashboard while for the reCAPTCHA, use Google’s admin console( v2 checkbox, Invisible, or v3 score-based.
- Check the Noptin Newsletter Forms checkbox and save your changes.
That’s how easy it is to keep your Noptin Signup forms bot-free. Test your frontend form to confirm everything works smoothly.
Double opt-in lays a strong foundation, but combining it with Hizzle CAPTCHA (especially Cloudflare Turnstile) builds an rock solid defense for your newsletters.
The result? Cleaner lists, higher open rates, and thrilled subscribers.
