What Should I Look For in an Anti-Spam Contact Form?

These are some of the essential features to look for when considering anti-spam contact forms:

  • CAPTCHA Integration: CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a widely used method to differentiate between humans and automated bots. Ensure your contact form plugin supports CAPTCHA, and ideally, it should offer options for both traditional text-based CAPTCHAs and Google reCAPTCHA.
  • Akismet Integration: Akismet is a robust spam filtering service by Automattic (the company behind WordPress). Many WordPress contact form plugins integrate with Akismet, allowing you to use its powerful spam detection capabilities for your forms.
  • IP Blocking and Blacklists: The ability to block specific IP addresses or domains associated with known spam sources is useful. Some form plugins come with pre-built blacklists, while others allow you to create your own.
  • Multiple Detection Methods: Effective anti-spam form plugins often use multiple methods, such as CAPTCHA, honeypot, and machine learning algorithms, to detect spam. Look for a plugin that employs a combination of these techniques.

8 Best Anti-Spam Contact Forms for WordPress

1. WPForms

The WPForms homepage

WPForms tops our list of plugins for anti-spam contact forms thanks to its user-friendly functionality and full suite of features. WPForms provides all of the tools you need to prevent spam from making it through your contact forms.

Not only does WPForms support Google reCAPTCHA, hCaptcha, and Cloudlfare Turnstile captcha integration, but the plugin allows you to create your own custom CAPTCHA element to use on your forms.

Or, if you prefer an alternative to CAPTCHA, you can easily integrate Akismet with your contact forms to filter out spam. And because WPForms works with Elementor for free, you can take advantage of WPForms’ supported anti-spam options to replace Elementor Forms, which offer very basic spam protection.

Our guide on using Akismet with Elementor Forms explains this process in detail.

Selecting reCAPTCHA in the CAPTCHA settings

But it’s the variety of spam filtering tools that make WPForms the best choice for creating anti-spam contact forms.

With IP address and email address filters, for example, you can block repeat offenders from making it through to your site. You can even filter the countries you allow to submit contact forms.

Spam protection and Security settings

Additionally, instead of offering a honeypot field (which bots are able to get through), WPForms provides an anti-spam token with each form. In the background, a distinct, hidden token is included with every submission. This token remains undetected by automated spam bots, so they can’t submit the form. But, real users don’t even know the token is there.

Here’s a summary of WPForms’ anti-spam features:

  • Google reCAPTCHA and hCaptcha, custom CAPTCHA, Cloudflare Turnstile captcha
  • Akismet integration
  • Filters by IP address, email address, entry spam status, profanity blockers
  • Anti-Spam Token default with each form

Plans and Pricing: Paid licenses start at $49.50 per year.

2. Formidable Forms

Formidable Forms

Formidable Forms is another great plugin that offers the anti-spam features you need to protect your contact forms.

Like WPForms, the forms created with this plugin are friendly to Google reCAPTCHA and hCaptcha. Formidable Forms also offers a Turnstile addon, along with an addon to use the plugin with Akismet. Plus, like WPForms, Formidable Forms will block certain IP addresses of your choosing from submitting forms or uploading files to your site.

However, Formidable Forms utilizes a honeypot for preventing spam from getting through a form, whereas WPForms does not. The plugin does, though, offer a Javascript token option, which generates a token specific to your site and is good for at least 24 hours. The token just doesn’t come default with the form like it does with WPForms.

Here’s a look at all the anti-spam features offered by Formidable Forms:

  • Google reCAPTCHA and hCaptcha, Cloudflare Turnstile captcha
  • Akismet integration
  • IP address blocking, comment blacklisting
  • Honeypot field
  • JavaScript token option available

Plans and Pricing: Upgraded plans come in at $39.50 per year.

3. Gravity Forms

The Gravity Forms homepage

Gravity Forms is another choice for a plugin that offers all of the desired features on our list.

For starters, this plugin is compatible with Google reCAPTCHA versions 2 and 3, and it plays nicely with Akismet. As for blocking and filtering, the Gravity Perks Blocklist addon can be used to validate submissions against the WordPress Disallowed Comment Keys. And, like other plugins listed here, Gravity Forms utilizes a honeypot field to trap spam.

One anti-spam feature we think is neat is the ability to apply conditional logic to the submit button. So, you can add a simple question to your form that a human visitor can easily answer but a bot couldn’t. Then, enabling the conditional logic for the submit button will make it display only if the question was answered correctly.

Gravity Forms also offers anti-spam extras in the form of useful addons like the ZeroSpam addon and the Gravity Perks Limit Submissions option.

These are all the anti-spam features offered by Gravity Forms:

  • Google reCAPTCHA
  • Akismet integration
  • Gravity Perks Blocklist addon for validating submissions against the WordPress Disallowed Comment Keys
  • Honeypot field
  • Additional anti-spam addons offered

Plans and Pricing: Paid licenses start at $59 per year.

4. Ninja Forms

The Ninja Forms homepage

The next plugin to make our list of anti-spam options, Ninja Forms offers all of the features you need for your contact forms.

Ninja Forms is compatible with Google reCAPTCHA versions 2 and 3, along with Akismet. The plugin also offers a Conditional Logic addon, which will block single email addresses that harass you with spam submissions and will block certain email domains from submitting a form.

This plugin also utilizes a honeypot field, and offers a field called the Anti-Spam field. This is an additional field on your form that can only be answered by a person.

Here’s a summary of the anti-spam features offered by Ninja Forms:

  • Google reCAPTCHA
  • Akismet integration
  • Conditional logic addon to block email addresses and domains
  • Honeypot field
  • Anti-Spam field

Plans and Pricing: Paid plans start at $99 per year.

5. Kali Forms

The Kali Forms homepage

Kali Forms is another form plugin that includes useful features for preventing spam from your contact forms.

This plugin makes our list thanks to its basic essential features that come with a low plan price. Like many plugin options here, Kali Forms is compatible with Google reCAPTCHA (version 2) and integrates with Akismet. The forms created with this plugin also include a honeypot field to filter spam.

Here’s a quick summary of Kali Forms’ anti-spam features:

  • Google reCAPTCHA
  • Akismet integration
  • Honeypot field

Plans and Pricing: Upgraded plans start at $29.

6. Happyforms

The Happyforms homepage

Next on our list, Happyforms offers a handful of desired features for preventing spam.

This plugin integrates with Google reCAPTCHA versions 2 and 3, and is compatible with WordPress disallowed comment keys. Happyforms does use a honeypot field on every form created, but the plugin also offers additional protection —  every submission is “signed” with a secret key that’s calculated from the submitted data.

We think that’s a pretty neat feature!

Here’s a summary of all the anti-spam tools:

  • Google reCAPTCHA integration
  • Compatible with WordPress disallowed comment keys
  • Honeypot field
  • Secret key that “signs” the submission

Plans and Pricing: Paid plans start at $79 for a website.

For a plugin that tackles a lot more than forms, Formstack completes our list.

FAQ About Anti-Spam Contact Forms

As the best form-building plugin around, we get asked a lot of questions about preventing spam with contact forms. Here’s what we’re asked about the most:

Why doesn’t WPForms use a honeypot field?

In the past, we utilized a honeypot field for spam prevention. However, we phased it out due to the increasing sophistication of modern spambots, which can easily circumvent such measures.

In its place, we’ve introduced a highly efficient approach for combatting contact form spam in WordPress – the anti-spam token. This method is particularly advantageous because it requires no action from the user to successfully navigate the spam check on your online forms.
