At roughly 10,000 active installs, it sits well below mainstream anti-spam plugins but has a clear niche audience using CF7.

A perfect maintenance score reflects the recent update on April 21, 2026 and confirmed compatibility with WordPress 6.9.4.

User Rating

13/15

A rating of 84 out of 100 from 12 reviews is solid, though the small sample size means it should be read with some caution.

Support Health

8/15

Support health is the weak link, with only 1 thread opened and a 0.0% resolution rate, suggesting the developer is not actively engaging user-reported issues.

WP Compatibility

What It Does

AntiSpam for Contact Form 7 adds a lightweight spam filter layer to Contact Form 7 forms, using techniques such as a honeypot field and optional GeoIP checks to block automated bot submissions before they reach your inbox. It works alongside CF7 without requiring you to add CAPTCHA challenges or third-party API keys to every form.

Who It's For

This plugin is best for small to mid-sized WordPress sites that rely on Contact Form 7 for lead capture, service inquiries, or support requests and want a set-and-forget spam blocker without visible user friction. It suits local businesses, agencies, and solo operators who do not want to pay for a SaaS anti-spam subscription or bother visitors with puzzles.

Who Should Skip It

If you run a high-traffic site with heavy spam pressure across comments, registration, and multiple form plugins, a broader solution like Akismet or CleanTalk will cover more ground. Sites that do not use Contact Form 7 get no value from this plugin at all.

The Bottom Line

AntiSpam for Contact Form 7 is a focused, well-maintained plugin that does one job reasonably well for CF7 users, scoring 78.01 out of 100 in our assessment. The weak support track record and small install base mean it is a sensible pick for low-stakes CF7 sites rather than a replacement for a full anti-spam platform.

Pick Akismet if you want the most battle-tested spam filter on the market, covering comments and contact forms with a huge install base of 6 million.

Really Simple Security 99/100

Choose this when your priority is overall site security and SSL rather than form-specific spam filtering.

Wordfence Security 97/100

Go with Wordfence if you need a full firewall and malware scanner in addition to spam blocking.

Jetpack 94/100

Pick Jetpack when you want an all-in-one suite that bundles spam protection, backups, performance, and growth tools.

CleanTalk Anti-Spam 92/100

Choose CleanTalk if you want a dedicated cloud-based spam firewall that blocks bots before they ever hit WordPress.
