**Excerpt:** Contact form spam isn't just a harmless nuisance. It can threaten the overall security of your website and your organization.

Thankfully, there are ways to effectively combat contact form spam in WordPress that don't require you to deal with it manually.

In this post, we'll walk explain how you can use different techniques to block contact form spam in WordPress.

**Content:**

Contact form spam can waste your team’s time, damage your domain’s sending reputation, and expose your site to malicious links. Blocking it doesn’t require manual effort.

This guide covers 12 techniques for stopping contact form spam in WordPress, from enabling built-in protection to blocking repeat offenders by email address or IP.

### Why Contact Form Spam Is Dangerous

Contact forms are common targets for malicious spam programs. Here are some ways that spambots can harm your site by abusing contact forms:

- **Submit harmful links:** Spambots with malicious intent can use your contact form to submit links that may contain malware. If any user from your team clicks the link, the malware might infect your whole organization, including your WordPress site.
- **Email deliverability issues:** Every form submission generates a notification email. During a spam attack, your site can end up sending unusual volumes of mail in a short time. This can trigger [unsolicited or bulk email errors](https://wpmailsmtp.com/how-to-fix-error-due-to-unsolicited-or-bulk-email-in-wordpress/) and, since Gmail and other major providers now permanently reject mail from flagged senders rather than deferring it, can do lasting damage to your domain’s sending reputation.
- **Denial of Service (DoS):** Some bots are highly efficient at repeatedly filling your forms to their limit. The goal of DoS bots is to overwhelm your website with tons of requests made in a short span of time. This may slow down your site, affect your form functionality for real users, and may even cause a site outage.
- **Hacking:** Automated brute force attack programs can target sites with user registration and login forms with the goal of hacking users. This is extremely dangerous because it can lead to account takeovers, information leaks, and data losses.
- **Productivity losses:** If your support staff has to filter through tons of spam entries, it affects their ability to respond to real users quickly. The impact on productivity may hurt your brand reputation and translate to lots of missed opportunities for conversions.

These are some of the ways that [spam can cause a lot of trouble for your site](https://wpmailsmtp.com/why-am-i-getting-increased-spam-emails/).

The methods below cover the best tools and techniques for getting rid of contact form spam. AI-generated spam submissions have increased significantly in recent years, so the most effective approaches use multi-layered detection rather than a single CAPTCHA solution.

Let’s dive into it.

### 1. Get a WordPress Form Plugin With Built-in Spam Protection

The most important step you can take to prevent contact form spam in WordPress is to use a plugin that has strong built-in spam protection features.

There are a lot of WordPress form plugins out there, but many don’t support reliable anti-spam methods.

For [automated spam prevention](https://wpmailsmtp.com/how-to-stop-form-spam-with-ai-filters/) built directly into your contact form, we recommend WPForms.

[WPForms](https://wpforms.com/pricing/) is a form builder with strong built-in tools for blocking contact form spam, as we’ll show below. It also comes with a variety of other useful features that you can learn more about in our [WPForms review](https://wpmailsmtp.com/wpforms-review/).

![WPForms homepage](https://wpmailsmtp.com/wp-content/uploads/2023/11/WPForms-Website-1024x640.png)After you [install WPForms](https://wpforms.com/docs/install-wpforms-plugin/), go ahead and [add a form to a page in WordPress](https://wpmailsmtp.com/how-to-add-a-form-to-a-page-in-wordpress/). You can then choose from a number of anti-spam methods available to you.

We’ll start with the most reliable option first.

### 2. Use WPForms Modern Anti-Spam Protection

WPForms uses a built-in multi-layered approach to detect and prevent spam. It runs silently by default and is our [top recommended reCAPTCHA alternative](https://wpmailsmtp.com/best-recaptcha-alternatives/).

Modern anti-spam protection is enabled by default in WPForms and runs silently in the background to fight spam. You can access the settings for it by navigating to **Settings » Spam Protection and Security** from your WPForms visual interface.

![Spam protection settings](https://wpmailsmtp.com/wp-content/uploads/2022/04/spam-protection-settings.png)Then, make sure that the toggle button next to **Enable modern anti-spam protection** is activated.

![](https://wpmailsmtp.com/wp-content/uploads/2025/04/enable-modern-anti-spam-protection-1024x716.png)When this setting is activated, it will prevent a form from being submitted when a spam bot triggers the spam protection.

You also have the option to store spam entries in your WordPress database to review submissions and easily recover any false-positive entries.

The **Enable minimum time to submit** option is also enabled by default and set to **2 seconds**. But you can change this minimum time to any value you like. This setting helps to prevent bots from submitting your form as it will prevent submissions before the usual time it would take a human to fill out the form.

WPForms anti-spam protection is more privacy-friendly than CAPTCHA-based alternatives and works without interrupting the user experience.

### 3. Include reCAPTCHA

WPForms also supports third-party spam prevention tools like Google’s reCAPTCHA. This is a powerful method of spam protection, though setup takes a few more steps than enabling the built-in protection in Method 2.

You can watch the video to see a demo of the process or keep reading for step-by-step instructions.

Currently, there are 3 different types reCAPTCHA:

- **Checkbox reCAPTCHA v2:** This reCAPTCHA version has a checkbox that a user must click to verify that they’re not a bot. If user activity seems suspicious, it might ask you to do a small image verification test to confirm that you’re a real user.
- **Invisible reCAPTCHA v2:** With invisible reCAPTCHA, users don’t see a checkbox at all. Rather, this reCAPTCHA service analyzes user behavior to identify and block bots.
- **reCAPTCHA v3:** Although both services above may occasionally show an image challenge, reCAPTCHA v3 works completely silently in the background. It’s an advanced spam prevention tool but it can be a little too sensitive and block human users sometimes.

To add reCAPTCHA to your form, open your WordPress admin area and go to **WPForms » Settings**.

![WPForms settings](https://wpmailsmtp.com/wp-content/uploads/2022/04/wpforms-settings.png)Click on the **CAPTCHA** tab on the horizontal bar below the WPForms logo.

![WPForms CAPTCHA](https://wpmailsmtp.com/wp-content/uploads/2022/04/wpforms-captcha.png)This page will show the available CAPTCHA options in WPForms. Select **reCAPTCHA**.

![WPForms recaptcha](https://wpmailsmtp.com/wp-content/uploads/2022/04/wpforms-recaptcha.png)Now, select the reCAPTCHA version that you’d like to set up. We recommend Invisible reCAPTCHA v2 for its user-friendliness, but you can decide on other options as well.

![recaptcha options](https://wpmailsmtp.com/wp-content/uploads/2022/04/recpatcha-boxes.png)To configure reCAPTCHA, you’ll now have to visit the [reCAPTCHA site](http://www.google.com/recaptcha/intro/index.html) on a new browser tab and click on **Admin Console**.

![admin console recaptcha](https://wpmailsmtp.com/wp-content/uploads/2022/04/admin-console.png)If prompted, sign in to your Google account now. After logging in, you’ll have to provide your site’s domain name to register it and select your preferred reCAPTCHA under the **reCAPTCHA type** section.

![](https://wpmailsmtp.com/wp-content/uploads/2025/04/Register-a-new-site-with-Google-reCAPTCHA-1024x712.png)Next, enter your website’s domain name under **Domains.** Make sure to only type the part that comes after `https://` in your URL.

![recaptcha domain](https://wpmailsmtp.com/wp-content/uploads/2022/04/type-recaptcha-domain.png)Then, accept the reCAPTCHA Terms of Service and checkmark alerts if you’d like to receive notifications.

![recaptcha settings google terms](https://wpmailsmtp.com/wp-content/uploads/2022/04/recaptcha-settings-google-terms.png)Click on **Submit** to save the settings. You’ll now see a message saying that your domain has been registered, with a site key and secret key underneath.

![site key and secret key](https://wpmailsmtp.com/wp-content/uploads/2022/04/registered-new-recaptcha-1.png)Switch to the browser tab where you have the **WPForms » Settings** page open and copy and paste the reCAPTCHA site and secret keys in the corresponding fields.

![wpforms secret recaptcha keys](https://wpmailsmtp.com/wp-content/uploads/2022/04/wpforms-site-secret-recaptcha-keys.png)Press the **Save Settings** button to finish your reCAPTCHA setup.

To add the reCAPTCHA field to your form, simply use the WPForms drag and drop interface to place the field onto your form.

![Form builder recaptcha field](https://wpmailsmtp.com/wp-content/uploads/2022/04/form-builder-recaptcha-button.png)Your form will now display a reCAPTCHA badge on the frontend, indicating that you’ve successfully added the reCAPTCHA spam prevention to your form.

![recaptcha badge](https://wpmailsmtp.com/wp-content/uploads/2022/04/recaptcha-badge.png)Next, we’ll look at another popular spam prevention service.

### 4. Use hCaptcha in Your Form

hCaptcha is very similar to Google’s reCAPTCHA, but it’s a more privacy-friendly spam blocking service. You can watch the video to walk you through the process or continue with the written instructions below.

To connect hCaptcha service with WPForms, head over to **WPForms » Settings** from your WordPress dashboard.

![WPForms settings](https://wpmailsmtp.com/wp-content/uploads/2022/04/wpforms-settings.png)On the settings page, click on the **CAPTCHA** tab located on the horizontal bar.

![WPForms CAPTCHA](https://wpmailsmtp.com/wp-content/uploads/2022/04/wpforms-captcha.png)Select **hCaptcha** from the available options.

![Select hCaptcha](https://wpmailsmtp.com/wp-content/uploads/2022/04/select-hcaptcha.png)As before, switch to a new browser tab and visit [hCaptcha](https://www.hcaptcha.com/) to sign up with the service.

![hCaptcha signup](https://wpmailsmtp.com/wp-content/uploads/2022/04/hcaptcha-signup.png)On the next screen, choose a hCaptcha plan. The free plan works perfectly well for small sites, so we’re going to work with that for this tutorial.

![Choose the free hCaptcha plan](https://wpmailsmtp.com/wp-content/uploads/2022/04/choose-free-hcaptcha-plan.png)After you’ve selected your plan, go ahead and fill out the form to create your hCaptcha account.

![hCaptcha sign up form](https://wpmailsmtp.com/wp-content/uploads/2022/04/h-captcha-sign-up.png)When you’ve finished the sign up process and logged into your dashboard, click on the **New Site** button to proceed.

![Press the New Site button](https://wpmailsmtp.com/wp-content/uploads/2022/04/new-site-hcaptcha.png)At the top, you can enter a name for your hCaptcha sitekey. Then scroll down to the General Information section and enter the name of your domain. Press **Add New Domain** when you’re done.

![Add domain to hCaptcha](https://wpmailsmtp.com/wp-content/uploads/2022/04/enter-domain.png)Scroll down below to find the hCaptcha behavior modes. You can choose from different modes depending on whether you want users to always be presented with a challenge or keep your captcha more passive.

![hCaptcha behavior](https://wpmailsmtp.com/wp-content/uploads/2022/04/hcaptcha-behavior.png)Next, scroll down again to the Passing Threshold section. Here, you can set the difficulty level of the captcha challenges.

![Passing threshold](https://wpmailsmtp.com/wp-content/uploads/2022/04/passing-threshold.png)In most cases, the Moderate level of difficulty is reasonably effective at spam prevention without compromising user experience (you can always change this later if needed).

Now, scroll back to the top and press **Save.**

![save hcaptcha settings](https://wpmailsmtp.com/wp-content/uploads/2022/04/save-hcaptcha-settings.png)You’ll now be taken to the next page, where you’ll find your added sites listed. Click on the **Settings** button next to the domain that you just added.

![Active sites settings](https://wpmailsmtp.com/wp-content/uploads/2022/04/active-sites-settings.png)Inside the settings, scroll down to the Sitekey and **Copy** it.

![Copy site key](https://wpmailsmtp.com/wp-content/uploads/2022/04/copy-sitekey.png)Paste your Sitekey to a text editor like Notepad for now. We’ll need this soon.

When you’ve done that, click on your profile icon at the top-right and select **Settings.**

![hcaptcha settings](https://wpmailsmtp.com/wp-content/uploads/2022/04/hcaptcha-settings-1.png)You’ll find your Secret Key here. Click on the **Copy Secret Key** button.

![Copy secret key](https://wpmailsmtp.com/wp-content/uploads/2022/04/copy-secret-key.png)Now that you have both your Site Key and your Secret Key, return to the WPForms hCaptcha settings page and paste your keys in the appropriate fields.

![wpforms hcaptcha keys](https://wpmailsmtp.com/wp-content/uploads/2022/04/wpforms-hcaptcha-keys.png)Then, click on **Save** to complete hCaptcha setup for WPForms.

Now, you can use the **hCaptcha field** when building your form using WPForms.

![hCaptcha form builder](https://wpmailsmtp.com/wp-content/uploads/2022/04/form-builder-hcaptcha.png)You should see the hCaptcha badge on the top of your form when it’s successfully added to it.

![hcaptcha badge](https://wpmailsmtp.com/wp-content/uploads/2022/04/hcaptcha-enabled-badge.png)Your form is now protected from spam by hCaptcha. If you’d like more detailed instructions, take a look at our guide to [adding CAPTCHA to your contact form using hCaptcha](https://wpmailsmtp.com/how-to-add-captcha-to-a-contact-form-in-wordpress/).

### 5. Use Cloudflare Turnstile

Cloudflare Turnstile is a free, privacy‑first alternative to Google reCAPTCHA and hCaptcha. It can run completely invisibly, so your visitors never have to solve a puzzle.

Watch the video or follow the steps below to add it to any WPForms form:

To get started, in your WordPress dashboard go to **WPForms » Settings » CAPTCHA** and pick **Turnstile** from the list of providers.

![Activate Turnstile anti-spam](https://wpmailsmtp.com/wp-content/uploads/2025/04/select-cloudflare-turnstile-1024x483.png)A pair of empty key fields will appear. Now, open a new tab, sign in to your Cloudflare account and select **Turnstile » Add site**.

![Add Turnstile site](https://wpmailsmtp.com/wp-content/uploads/2025/04/add-turnstile-site-1024x500.png)Enter a name and your site’s domain in the appropriate fields.

![Enter Turnstile website domain](https://wpmailsmtp.com/wp-content/uploads/2025/04/enter-website-domain-1024x591.png)Next, choose a widget type (**Managed** works for most sites).

![Select Turnstile widget](https://wpmailsmtp.com/wp-content/uploads/2025/04/select-widget-type-1024x626.png)Now, click **Create** to reveal your **Site Key** and **Secret Key**.

Copy the Site Key and Secret Key from Cloudflare into the matching fields back in **WPForms Settings**.

![Enter Turnstile site key and secret key.](https://wpmailsmtp.com/wp-content/uploads/2025/04/enter-site-key-and-secret-key-1024x426.png)If you want, you can change the fail message that displays when a user tries to submit the form without completing the Cloudflare Turnstile verification challenge. You can also choose the style of the widget (pick a **Light / Dark / Auto** theme) and optionally enable **No‑Conflict Mode** if another plugin or theme also loads Turnstile. Click **Save Settings**.

You can now enable Cloudflare Turnstile on any form. Open any form in the builder. Either drag the **Turnstile** field onto your form **or** go to **Settings » Spam Protection and Security** and toggle **Enable Cloudflare Turnstile**.

![Add Turnstile Field to Form](https://wpmailsmtp.com/wp-content/uploads/2025/04/add-turnstile-field-1024x486.png)A small Turnstile badge in the corner confirms it’s active.

![Turnstile enabled form](https://wpmailsmtp.com/wp-content/uploads/2025/04/turnstile-enabled-badge-1024x429.png)### 6. Use Custom CAPTCHA

We’re big fans of custom CAPTCHA because it’s very effective and doesn’t require image-based challenges that can sometimes be a bit tricky for real users.

WPForms Pro users can get the Custom CAPTCHA addon to include simple math-based quizzes or a custom question and answer in your forms for spam prevention.

To set up Custom CAPTCHA, launch the form builder interface.

![Contact form builder](https://wpmailsmtp.com/wp-content/uploads/2022/04/contact-form-builder.png)Then, find the Custom CAPTCHA field under the **Fancy Fields** section. If you don’t have the Custom CAPTCHA addon yet, this field will be semi transparent. Click on it and you’ll be prompted to install the addon.

![Custom CAPTCHA field](https://wpmailsmtp.com/wp-content/uploads/2022/04/custom-captcha-field-grayed-out.png)When a popup appears, click on **Yes, Install and Activate** to proceed.

![Activate custom captcha](https://wpmailsmtp.com/wp-content/uploads/2022/04/custom-captcha-activate.png)The installation will take only 2-5 seconds to complete. The popup will display a success message once the Custom CAPTCHA addon is active. Click **Yes, Save and Refresh** to continue.

![save custom captcha](https://wpmailsmtp.com/wp-content/uploads/2022/04/save-refresh-custom-captcha.png)Now, drag and drop the Custom CAPTCHA field into your form. Click on the field once it’s added to your form to access its settings.

Here, you can select the type of CAPTCHA (math or custom question and answer) and add a description.

![Custom CAPTCHA example](https://wpmailsmtp.com/wp-content/uploads/2022/04/Custom-Captcha-example.png)If you choose **Math,** WPForms will automatically generate a simple arithmetic question that users must answer correctly. Spambots can’t answer these math questions, which is why this Custom CAPTCHA is a very effective contact form spam prevention technique.

Alternatively, you may choose **Question and Answer** as your CAPTCHA type. This allows you to create a question and set its correct answer.

![set questions and answers](https://wpmailsmtp.com/wp-content/uploads/2022/04/set-question-and-answer.png)You can add multiple questions by using the blue **(+)** icon next to the question field in settings.

Make sure to **Save** your form after you’re done making changes.

### 7. Enable Country & Keyword Spam Filters

WPForms lets you block submissions from specific countries or reject any entry that contains words you know are spammy.

To turn these filters on for any form, open your form in the builder and click **Settings » Spam Protection and Security**.

![Spam protection settings](https://wpmailsmtp.com/wp-content/uploads/2022/04/spam-protection-settings-1024x559.png)Scroll to **Filtering** and toggle on **Enable Country Filter** or **Enable Keyword Filter**.

![turn on keyword filter in wpforms](https://wpmailsmtp.com/wp-content/uploads/2024/05/turn-on-keyword-filter-in-wpforms-1024x676.png)Use the dropdown to choose **Allow** or **Deny** for selected countries or add blocked keywords line‑by‑line.

Any blocked attempt is stopped before it reaches your inbox, so legitimate users never see an error message.

### 8. Block URLs Inside Text Fields

Many spambots are designed to distribute phishing links through contact forms. Sometimes, there may even be a real person submitting malicious links using your forms. As you know, CAPTCHA and form tokens can’t stop a real human spammer.

So if you’re receiving suspicious links through your form, you might want to block URL submissions in your form fields entirely.

You can block URLs in your form fields by adding a PHP script. If you want to learn about adding code snippets to your forms, see this [tutorial on adding custom PHP for WPForms](https://wpforms.com/developers/how-to-add-custom-php-or-javascript-for-wpforms/).

Use the code snippet below to block URLs within the **Single Line Text** and **Paragraph Text** fields of your form.

When you have added the above code to your form, WPForms will display a “No URLs allowed” error if a user tries to submit a link into your text fields.

### 9. Use Antispam WordPress Plugins

There are several powerful antispam plugins available for WordPress. Most of these plugins work by scanning databases of known spam content including patterns of words that appear repeatedly in spam, common links, email addresses, and even IP addresses of users and bots.

Some popular WordPress antispam tools are [Akismet](https://wordpress.org/plugins/akismet/) and [Jetpack](https://wpmailsmtp.com/go/jetpack/ "Jetpack"). Remember that these plugins operate across your whole site, so they’ll not only limit contact form spam but also reduce spam comments on your blog.

We’d particularly recommend Akismet, as WPForms comes with a native Akismet integration. When enabled, this integration is an excellent way of [filtering contact form spam in WordPress](https://wpmailsmtp.com/how-to-filter-contact-form-spam-with-akismet/). Note that Akismet’s free plan covers personal, non-commercial use only. Business and commercial sites need a paid Akismet plan. Jetpack’s spam filtering is also a paid feature, available as a standalone add-on or as part of a Jetpack paid plan.

Using these spam prevention WordPress plugins along with the other techniques shown above strengthens your overall site security.

### 10. Block Email Addresses of Repeat Spammers

The email address field can be quite handy when it comes to filtering human spammers. Since human spammers can easily bypass CAPTCHA and form tokens, you need extra safeguards to block them.

In cases where a website is frequently receiving spam from similar email addresses, blocking suspect email addresses is the way to go.

To block an email address, click on the **Email** field in WPForms. Then, select the **Advanced** tab on the left-hand pane.

Scroll down and click on the **Allowlist / Denylist** dropdown, then select **Denylist**.

![email denylist](https://wpmailsmtp.com/wp-content/uploads/2022/04/email-denylist.png)Now you can add email addresses that you want to block submissions from in the box under the **Denylist** option. You can enter multiple email addresses separated by commas.

You can use an asterisk \* to block email addresses with a partial match.

For instance, using an asterisk before an email domain (such as `*@domain.com`) will restrict all email addresses at that domain from submitting entries.

Or you can also block an email address starting with a particular username by putting an asterisk after it (such as `example*`).

These rules are great when you’re receiving spam from email addresses at the same domain or username.

Make sure to **Save** your form after building your blocklist.

### 11. Require Email Verification for New Users

Requiring email verification discourages spammers from signing up with fake addresses. Any user who can’t access the verification link won’t be able to complete registration.

WPForms allows you to set up email verification before a new user can register their account.

To add email verification, click on **Settings » User Registration** from the left-hand pane within the WPForms interface.

**Note:** You’ll need the **User Registration addon** for WPForms to access these settings. If you don’t have it, see [how to create a user registration form](https://wpforms.com/how-to-create-a-user-registration-form-in-wordpress/).

![user registration](https://wpmailsmtp.com/wp-content/uploads/2022/04/settings-user-registration.png)Then, click on **Enable User Registration**.

![Enable user registration](https://wpmailsmtp.com/wp-content/uploads/2022/04/enable-user-registration.png)Activate the **Enable User Activation** toggle button.

![enable user registration](https://wpmailsmtp.com/wp-content/uploads/2022/04/user-registration-enable-user-activation-1.png)This will expand a new menu where you can select your activation type as **User Email**.

Now, whenever a user tries to register their account on their site, they will have to provide a valid email address to receive a registration link. Meaning no spam from users with fake emails!

### 12. Blacklist Spammy IP Addresses

Blocking the IP addresses of spammers is not as efficient as other methods on this list because it’s easy to spoof an IP address using proxies and VPN services.

But if you notice a pattern of repeat spammers returning to your site, you can block their IP address to deny them access to your entire WordPress site.

To restrict users by IP address, go to **Settings » Discussion** from your WordPress dashboard, and enter the IP addresses that you want to block in the **Disallowed Comment Keys** box. If you have multiple IP addresses to block, make sure to add each IP address in a new line.

![WordPress blocklist](https://wpmailsmtp.com/wp-content/uploads/2022/04/blacklisted-ip-addresses.png)But how are you going to find IP addresses of spammers in the first place? For this, you’ll need to add the `{user_ip}` smart tag in your WPForms email notifications content.

Now, when you receive an email notification for a form submission, it will include their IP address within the email content.

If you notice that spam entries are coming from similar IP addresses, simply note them down and add them to the WordPress IP blocklist as shown above.
