Now for the juicy part! Follow along with this easy step-by-step tutorial to create your own stunning Mailchimp signup form. We‘ll be using the WPForms Pro plugin, which makes the whole process a total breeze.
Step 1: Install the WPForms Plugin
First things first, you‘ll need to install the WPForms plugin on your WordPress site.
Don‘t worry, it‘s super simple. Just follow these quick steps:
- Log into your WordPress dashboard and navigate to Plugins → Add New.
- Search for "WPForms" in the search bar.

Step 2: Create a New Signup Form
With WPForms installed, you‘re ready to create your first signup form!
- From your WordPress dashboard, go to WPForms → Add New.
- Enter a name for your form, like "Mailchimp Subscribe Form".
- Choose the "Newsletter Signup Form" template.
- You‘ll be taken to the drag-and-drop form builder. Here, you can add, remove, and rearrange fields however you‘d like.

The WPForms drag-and-drop form builder makes it easy to create custom signup forms.
We recommend including the following fields in your form:
- Name – Collect subscribers‘ names so you can send personalized emails. Just drag the Name field onto your form. You can even split this into First Name and Last Name.
- Email – The Email field is required so you can actually send emails to your new subscribers! Make sure to mark this field as Required.
- Custom Fields – Add extra fields to gather valuable data and segment your list later. For example, you might include a Dropdown field for "Interests", Checkboxes for "Email Preferences", or a Text field for "Company Name".
Step 3: Integrate Your Form With Mailchimp
Next, you‘ll connect your fancy new form to Mailchimp so that new submissions are automatically added to your email list. WPForms makes this a snap!
- From the form builder, go to Marketing → Mailchimp.
- Click the "Add New Connection" button.
- Enter any nickname for this integration, then paste in your Mailchimp API key. (You can grab this from your Mailchimp account under Profile → Extras → API Keys.)
- Click "OK" to connect your Mailchimp account.
- Configure the following settings:
- Mailchimp Account – Select the account you just connected.
- Mailchimp Audience – Choose the email list where you want to add new subscribers.
- Action – Choose "Subscribe" to add new emails to your list.
- Field Mapping – Match up your form fields to the corresponding Mailchimp fields. For instance, map the Email field to "Email Address" and any name fields to "First Name" and "Last Name".
- Options – We recommend enabling Double Opt-In to ensure you‘re only adding high-quality subscribers to your list.
- Click "Save" to store your integration settings.
That‘s it! Now, any new signups through your form will be instantly synced to Mailchimp.
Step 4: Customize Your Form Confirmations and Notifications
Before we publish your masterpiece, let‘s take a second to customize what happens after someone submits your form.
Form Confirmations

- Message – Display a success message directly on the page.
- Show Page – Direct users to a specific page on your site, like a download or thank you page.
- Go to URL (Redirect) – Send subscribers to another website.
- Customize the confirmation message to your liking, then click "Save".
Email Notifications
- From the form builder, go to Settings → Notifications.
- If you want to get an email whenever someone signs up through your form, enter the email address where the notification should be sent.
- Customize the email subject line and message body however you‘d like. You can even use Smart Tags to dynamically populate the email with information from the form submission, such as the subscriber‘s name.
- When you‘re finished editing, click "Save".
Step 5: Publish Your Mailchimp Signup Form
Your subscribe form is locked, loaded, and ready to be unleashed upon the world! Just follow these steps to publish it on your WordPress site.

Advanced Tips to Skyrocket Your Mailchimp Form Conversions
Want to take your signup form to the next level? Try implementing some of these advanced tactics:
1. Offer a Highly-Relevant Lead Magnet
One of the most effective ways to entice visitors to subscribe is by offering them a valuable resource in exchange for their email. This could be an ebook, whitepaper, video course, discount code, or any other type of content that solves a problem for your target audience.
To maximize conversions, make sure your lead magnet is:
- Highly relevant to your niche and audience
- Actionable and instantly usable
- Delivered immediately after signup
2. Use an Exit-Intent Popup
Did you know that over 70% of visitors who abandon your site will never return? (Source) Yikes.
An exit-intent popup allows you to capture emails from visitors right before they leave your site. By triggering your form at this crucial moment, you can convert abandoning visitors into subscribers and customers.
Here‘s an example of an exit popup created with OptinMonster:

An exit-intent popup appears right before a visitor leaves your site, giving you one last shot to capture their email.
3. A/B Test Your Form
Ever wonder what would happen if you tweaked your headline, form layout, or call-to-action button?
A/B testing lets you pit two different versions of your form against each other to scientifically determine which one performs better. By continuously testing and optimizing your form, you can identify small changes that lead to big improvements in your conversion rate.
Here are some key elements to test on your signup form:
- Headline copy
- Call-to-action button copy and color
- Number and type of form fields
- Form layout and design
- Offer/lead magnet
- Popup timing and trigger
Tools like Google Optimize make it easy to set up A/B tests on your WordPress site without any coding. Here‘s a helpful guide from MonsterInsights to get you started with conversion optimization.
