A simple, quiet way to stop spam
Zero Spam keeps unwanted submissions out without interrupting the user experience. No captchas, no required configuration: activate the plugin and it starts blocking bots with signed, time-limited tokens. Used to block spam on over 100,000 Gravity Forms sites.
- Non-obtrusive spam protection, no captchas
- Works instantly upon activation
- Signed, time-limited tokens that bots can’t reuse


Extra tools to stay informed and protected
Get visibility into blocked entries and layer Zero Spam alongside your existing anti-spam solutions for stronger protection.
- Optional email summaries of recent spam activity
- Shield Security silentCAPTCHA integration as an additional spam signal
- Control the order your spam checks run in

- Compatible with Akismet, honeypot fields, WP Armor, and more
Reject unwanted emails and let AI review the edge cases
Email rejection rules let you block, flag, or log submissions that match email addresses, domains, wildcards, or regular expressions you define. Connect an AI service (OpenAI, Anthropic, or Google Gemini) in WordPress 7.0 or newer, and AI review adds a second opinion: flagging spam the token check missed and rescuing legitimate submissions blocked by mistake.
- Import email rules in bulk and set field-specific overrides
- AI review is off by default and opt-in per site and per form
- No API keys stored: nothing is sent to AI unless you enable it
