Want a simple way to add a checkbox in your Mailchimp signup form?
A simple checkbox can skyrocket your Mailchimp lists by allowing visitors to sign up while they fill out your form!
And this post will show you how to add one to your forms to see your Mailchimp audience grow today.
Let’s get started.
Why add a checkbox to your Mailchimp signup form?
People hate receiving emails they didn’t sign up for.
It instantly creates a bad experience, which is the last thing you want when building trust and confidence with website visitors.
So, adding a checkbox is an easy way to get clear consent from your subscribers to receive your emails. And that helps you avoid negative interactions, comply with anti-spam laws, and respect your subscriber's privacy.
Plus, it helps you zero in on your most engaged subscribers. After all, if a user checks your checkbox for your emails, they send you a clear message:
“I want to hear what you have to say!”
That means higher open rates, conversions, and an active email list overall.
And that’s HUGE for your website or business.
How to add a checkbox in a Mailchimp signup form
To get started, we recommend using Formidable Forms, the most advanced form builder for WordPress.
Formidable has a Mailchimp add-on included in its Plus plan. So, with a simple add-on, you can create any Mailchimp form you want — contact forms, signup forms, or newsletter subscriptions.
So, get Formidable Forms installed and activated, then we’ll start with a few simple steps:
- Create your Mailchimp form and add a checkbox
- Connect Mailchimp to your form
- Set up your form’s conditional logic
- Customize your form (optional)
- Display your form
1. Create your Mailchimp form and add a checkbox
First, head to Formidable → Forms and click Add New to create a new form.
Next, you can choose from one of Formidable’s pre-made templates to save time or Blank Form to start from scratch.
Then, give your form a name and click Create, and the plugin will take you to its drag and drop form builder. You can begin adding any form fields you need for your forms, like Text, Email, or Radio Buttons.
You can customize the fields as you need to use the field options in the left sidebar.
The input type Checkboxes field is what we want to focus on, though.

Add a checkbox field to your form, and two checkboxes appear. You can keep this to have a Mailchimp signup with multiple checkboxes. But we’ll use one subscribe checkbox for this example.
So, in the Field Options sidebar, delete the Option 2 checkbox and rename the Option 1 field. If you want to make the checkbox required for your Mailchimp signup form, check the Required field.

Next, scroll down to the Advanced section in the Field Options and choose None under the Label Position.

This will ensure only your message next to the checkbox shows.
So, your form should look like this now:

Now that your form is ready, let’s connect Mailchimp.
2. Connect Mailchimp to your form
In your WordPress dashboard, go to Formidable → Add-Ons and search for the Mailchimp add-on.

Click Activate to get the add-on installed and ready to go.
Next, go to Formidable → Global Settings → Mailchimp and enter your API Key from Mailchimp and click Update Options to connect your Mailchimp account.

The last thing we need to do is connect Mailchimp to your form. So, head to your form, go to Settings → Actions & Notifications and click Mailchimp.

A Mailchimp action will appear below, and you can customize it to fit your needs, like which mailing list, single or double opt-in, and more.

Once you set them up, click Update to save your changes, and Mailchimp is ready.
3. Set up your form’s conditional logic
Not everyone wants to sign up for your email list.
So you need a way to filter out those who don’t consent. And it’s as simple as adding conditional logic to your Mailchimp action.
So, scroll down to the bottom of the action and click Add Conditional Logic.
Next, set your conditional logic like this:

The form will only add visitors if they check the box.
Now, let’s look at changing your form’s design.
4. Customize your form (optional)
If you truly want your form to stand out, you need it be unique.
And the best way to do that is with Formidable’s Visual Form Styler. With just a few clicks and settings changes, your form looks beautiful.
So, head to the Style tab in your form, which will take you to the form styler.

You can choose from one of the pre-made design templates or click New Style to create one.
Next, name your style and click Create new style. The plugin will redirect you to the Form Styler, where you can customize your template.

Change the colors, border radius, and more from one simple menu. Feel free to play around with the options until you design a form that fits your site.
Once you’re finished, click Update to save your changes.
The only thing left to do is publish your form on your website!
5. Display your form
Head to the post or page where you want to show your form and add a new WordPress block.
Next, search for Formidable, add the Formidable WordPress block, choose your form from the dropdown menu, and the plugin will display your form.

Last, update your page; your form is ready to take submissions!
