Cloudflare, a popular content delivery network and security service, may inadvertently block the NS Pro triggering script as part of its automated security measures. This can happen because Cloudflare's Web Application Firewall (WAF) is designed to detect and block potentially harmful requests to protect your website from attacks. If our script is not recognized as safe, it might be flagged as suspicious activity, leading to unintentional disruptions in its functionality. This could prevent the script from executing as intended, thus not allowing NS Pro to send scheduled newsletters.

To ensure seamless operation, it is crucial to whitelist our User Agent in your Cloudflare WAF settings. By doing so, you allow Cloudflare to identify our script as a trusted source, thereby bypassing any restrictive security rules that might block it.
