Gravity Forms Zero Spam
Stop spam on your Gravity Forms without CAPTCHAs, puzzles, or any friction for real visitors.
What it does
Spam submissions waste your time and clutter your entries. Gravity Forms Zero Spam blocks them using server-side checks that run silently in the background, so the people filling out your forms never see a CAPTCHA, checkbox, or puzzle.
It works by adding a signed, time-limited token to each form. Most bots post directly to your server without loading the page, so they never get a token and their submissions are flagged as spam. You can also add email rejection rules, optional AI review, and Shield silentCAPTCHA detection on top of that first layer.
The plugin is free and works alongside Gravity Forms' built-in honeypot and reCAPTCHA tools, as well as third-party plugins like Akismet and CleanTalk. You can protect only the forms you choose, and optional summary emails tell you what was caught.
Key features
- Invisible token check blocks bots on submission without any visitor interaction
- Email rejection rules filter by address, domain, wildcard, or regular expression
- Optional AI review catches missed spam and rescues wrongly blocked submissions
- Optional Shield silentCAPTCHA adds bot detection as an extra server-side signal
- Per-form on/off toggle so you protect only the forms you want
- Configurable check order and stop-at-first-detection option when multiple checks are active
- Optional spam summary emails sent on a schedule or when a threshold is reached
Good for
Written from GravityKit’s own listing. Version and dates come straight from the source and are checked weekly.
Is this plugin free?
Yes, every feature described is included at no cost. You still need a Gravity Forms license for Gravity Forms itself.
Does AI review send my form data to an external service?
Only if you turn it on. Both AI tools are off by default. When enabled, data is sent through WordPress's built-in AI connectors; email addresses are masked, sensitive fields can be skipped, and the plugin never stores your API keys.
Will spam entries still trigger my email notifications?
No. When an entry is marked as spam, notifications and add-on feeds are skipped. The submitter sees the default Gravity Forms confirmation message instead of your custom one.
What version of Gravity Forms do I need?
Gravity Forms 2.3 or newer. Per-form control requires 2.5 or newer, and blocking submissions via email rejection rules requires 2.9.15 or newer.
