Protect your growth,
not the spammers.

Zero Spam helps you identify suspicious traffic so you can block spam, bots, and abuse before it wastes your time or reaches your users.

Plans mainly differ by:
– How many API requests you can make per month
– Whether you get basic info or deeper intelligence + report history
– How many sites/apps you can cover

It’s the number of times your site/app can ask Zero Spam to check a visitor/source in a month.
If you check every form submit, login attempt, or suspicious action, you’ll use more requests.

– Explorer: just trying it out
– Essentials: small site/app that wants better filtering
– Business: heavier traffic or you want abuse reports + email reports
– Platform: you run multiple sites/apps and want unlimited requests

Zero Spam is designed to be fast and lightweight. Most customers use it in ways that don’t affect the site experience (for example: checking only on signups, logins, and form submissions).

Zero Spam returns a threat confidence score plus supporting data (and on higher tiers, report history). That gives you flexibility to choose how strict you want to be. Many customers start in “log-only” mode, then tighten rules once they see results.

Yes — those are the most common use cases. It’s especially helpful anywhere spam and abuse show up repeatedly.

They’re signals from reporting history that help you understand if a source has been associated with abusive behavior. Business and Platform include these for stronger decision-making.

Yes. Payments are handled through secure payment processing and your card details are not stored directly on your server.

Yep. You can upgrade anytime as your traffic grows—and downgrade if your needs change.

When you hit the limit, you’ll stop receiving responses until the limit resets when your plan renews. If you expect spikes (sales, launches, campaigns), upgrading is the easiest way to avoid interruptions.

You can use one license key for one site/app at a time. If you migrate or change domains, you can move the key to the new one.

Free tools help, but they often rely on basic rules. Zero Spam adds confidence scoring and intelligence (and on higher tiers, reporting history) so you can reduce false positives, cut down junk leads, and protect accounts more reliably.

Usually immediately—spam and bot traffic patterns tend to show up fast. Most people notice reduced junk form submissions and fewer suspicious attempts within the first day or two.

Yes. Platform includes priority support and integration support. All plans are designed to be simple to get started, but we’re here if you need help.
