We host a wide array of websites that are completely different from one another yet there is one thing connects them all.


example spam emailIn September 2019, spam accounted for 54.68% of all email traffic.

Whether it’s unwanted emails sent directly to our clients’ email addresses or unsolicited contact form submissions – they’re all the same.

We don’t want them, our customers don’t want them and they are a complete waste of everyone’s time.

Now and then, we see a rise in spam to each of our clients contact forms.

It’s almost as if these bots or human spammers think their tactics will work.

Luckily, we have a great solution if you are using WordPress that will block spammers, bots and outreach emails from “SEO’s” and “web designers” looking to poach your clients.

This solution will help you stop contact form spam if you are using Caldera Forms.

The Basic Steps To Blocking Contact Form Spam

We’re only recommending free plugins.

Honestly, we looked at paid options to stopping WordPress contact form spam but we could not justify even mentioning them when there are free alternatives to hand.

1) Set Up A Honeypot

Bots are designed to read a form, fill out required fields and submit it’s content to you.

A honeypot is a hidden field that a bot will complete not knowing it is hidden and should be ignored.

Once it tries to submit the form it will not send.

Bots could be trained to read CSS and JS to look out for honeypot fields so this is a very basic step in spam prevention.

2)Contact Form Recaptcha Fields

Recaptcha is a great way to prevent spammers.

V2 and V3 of Google’s Recaptcha is quite groundbreaking technology.

Unfortunately, this is never a 100% proof method.

Captcha Farmers get paid to break or pass Recaptcha fields and human spammers or marketers will pass a bot test if they wanted to send you an email.

3) Contact Form Pagination

We host some huge websites. Some have tens of thousands of products that generate millions of visitors per month.

As you can imagine, the high volume of spam that comes through the form is infuriating.

We reduced the amount of spam with one simple trick.

We gave their customers the option to choose two options. Call us or submit a form.

Either a contact form or their telephone number would then be presented depending on what they chose.

This reduced bot spam by around 60%. Unfortunately pagination can be manipulated if the bot has been trained correctly so some still trickle through.
