After experiencing an influx of spam signups on my newsletter, I discovered that malicious users were utilizing compromised email addresses to spam my form. This is a common issue faced by website owners. To counteract this, I devised several strategies such as enabling double opt-in, using CAPTCHA to filter out bots, and employing services like Cloudflare for enhanced security. These measures can help ensure that only legitimate users subscribe to newsletters and protect against future spam attacks.
Double opt-in can help ensure that only genuine subscribers are added to your list by requiring users to confirm their email addresses before they receive your newsletter.
CAPTCHA is a critical tool to prevent automated bots from submitting forms, providing an extra layer of verification that human users are filling out your newsletter signup.
Using services like Cloudflare can protect your website from spam attacks by filtering out malicious traffic and enhancing overall security.
Spammers often use compromised email addresses to sign up for newsletters, either to pollute the list or to annoy the real email owners.
