How to stop spam emails being sent through Contact Form 7

The Contact Form 7 WordPress plugin is one of the most widely used web forms plugins available today. It provides an easy and secure way for website owners to receive feedback from their customers and visitors. However, spam emails can easily be sent through this platform, leading to a large number of unwanted messages. To combat this problem, there are several helpful tools available that can help stop spam emails from being sent through Contact Form 7.

By creating a Captcha monitor, website owners can ensure that only legitimate users have access to the form by requiring them to type in a code or answer a simple question. IP addresses and email addresses can be monitored regularly so that any suspicious activity is flagged and blocked immediately. Additionally, customized rejection messages can be created which will inform potential spammers why they were not able to send the form successfully.

Create a Captcha

Are you tired of receiving unsolicited emails through your website’s contact form? Many websites are plagued with spam emails that can be difficult to filter out. To prevent these unwanted messages, one effective solution is to create a Captcha on your contact form.

A Captcha is an acronym for ‘Completely Automated Public Turing test to tell Computers and Humans Apart’ – it is a type of challenge-response test used to ensure the user is not a robot. Generally, they require users to enter the text from an image or solve a basic math equation in order to submit the form. This makes it nearly impossible for robots or automated programs to get past them, thereby protecting your contact forms from malicious actors. We recommend using the reCAPTCHA service to protect your forms. It is a free service that offers a Captcha as an image, or in the form of a word.

Monitor IPs & Email Addresses

Monitoring IPs and email addresses is an important step for ensuring that spam emails are not sent through Contact Form 7. To help reduce the amount of spam sent through your contact form, it's critical to be aware of which IPs and email addresses are being used to send messages. Identifying and blocking these sources can help prevent spammers from bombarding your inbox with unsolicited emails.

There are a few different methods you can use to monitor IPs and email addresses. For example, you can check the headers on incoming emails to determine their source by looking at the “From” address or the “Received” information. You can also use software solutions such as Cloudflare or MX Toolbox to track suspicious IPs and blacklist them if needed. While most spam messages are easy to spot, some spammers employ more sophisticated techniques to avoid detection. For example, some spammers will attempt to blend in with your other traffic and make it look like their message was sent from an actual user.

Customize Rejection Messages

Spam emails are a nuisance to both you and your website visitors. Thankfully, there are ways to stop spam emails from being sent through Contact Form 7 on WordPress. One of the best methods is to customize rejection messages so that they become less attractive to spammers. This article will explain how you can customize rejection messages in order to keep your Contact Form 7 secure from spam.

Rejection messages are triggered when a user tries to send an email that does not meet certain criteria, such as incorrect formatting or invalid data entry. By customizing these rejection messages, you can create an unpleasant experience for spammers who are trying to fill out your Contact Form 7 with malicious intent.

Use Akismet Plugin

If you're using the Contact Form 7 plugin for your WordPress website, you know it can be a great way to keep in touch with your customers and visitors. However, if spam emails are sent through your contact form, it can damage your reputation and make it difficult to communicate with legitimate customers. Fortunately, there is an easy solution - use the Akismet Plugin!

Akismet has been developed by the same people who created WordPress, so you know it's reliable and secure. The plugin uses advanced algorithms to protect against spam emails being sent through Contact Form 7 forms. It also comes with a range of customization options so you can tailor the settings according to your needs. Akismet even checks submissions against its global database of known spammers before they reach your inbox, so you don't have to worry about dealing with unwanted messages again!

Use Honeypot Technique

The Honeypot technique is an effective way to stop spam emails from being sent through Contact Form 7. This method takes advantage of the fact that bots, unlike humans, fill out forms with ease. By adding a hidden field to the form, any automated submissions will be blocked and discarded before they reach their intended destination.

The honeypot technique works by adding an invisible field on your contact form that only robots are able to see. If a robot attempts to submit the form, it will automatically fill out this hidden field, which alerts you that there is a potential bot trying to send spam emails. You are then able to take action and block these messages from reaching their intended target. The Honeypot technique can also be used in other ways such as blocking malicious users from accessing websites or sending malicious links through email campaigns.


Spam emails can be very uncomfortable and annoying, especially if they are sent through Contact Form 7. Thankfully, there are several measures that can be taken to stop spam emails from being sent through this form. In conclusion, it is important for website owners and administrators to take the necessary steps to ensure that spam does not reach their inboxes.

The first measure to take when trying to stop spam emails from Contact Form 7 is to set up a CAPTCHA or reCAPTCHA tool on the contact form. This will help prevent bots from submitting the form and sending out unwanted emails. Additionally, setting up an email whitelist on the contact page will only allow certain people to use it while blocking all other potential spammers.
