How To Connect Convertkit To Squarespace

Integrating ConvertKit with Squarespace: A Step-by-Step Guide
Connecting ConvertKit, a robust email marketing platform, with Squarespace, a leading website builder, allows for seamless lead capture and automated communication. This integration enhances marketing efforts by enabling you to grow your email list and nurture subscribers directly from your website.
Method 1: Using Squarespace's Built-in Code Injection
This method involves using HTML forms provided by ConvertKit and embedding them into your Squarespace site through code injection. This approach offers flexibility in design and placement of your opt-in forms.
Step 1: Create a Form in ConvertKit
Must Read
Begin by logging into your ConvertKit account. Navigate to the "Landing Pages & Forms" section and click "Create New."
Select "Form" as your creation type. You'll be presented with several form templates. Choose one that suits your needs and customize it using ConvertKit's form editor. This includes adjusting the fields, colors, and overall appearance to match your website's branding.
Once your form is designed, save it. Navigate to the form's embed options.
Step 2: Obtain the Embed Code from ConvertKit
ConvertKit provides several embed options: Javascript, HTML, and WordPress. Select the "HTML" option. This will display the HTML code for your form. Copy this code to your clipboard.
Step 3: Inject the Code into Squarespace
Log in to your Squarespace account. Navigate to the page or specific area where you want to display the form. Click "Edit" on the page.

Add a "Code" block to your page. This can be done by clicking on an insert point (the tear-drop shaped icon) and searching for "Code."
Paste the HTML code you copied from ConvertKit into the "Code" block. Ensure that the "Display Source" option is unchecked. This will render the form instead of displaying the raw HTML code.
Click "Apply" and then "Save" to publish the changes. Your ConvertKit form should now be visible on your Squarespace page.
Method 2: Using Zapier for Advanced Integrations
Zapier is a third-party automation tool that connects different web applications. This method provides more advanced integration options, such as automatically adding new Squarespace customers or form submissions to your ConvertKit lists.
Step 1: Connect ConvertKit and Squarespace to Zapier
Create a Zapier account or log in to your existing account. Click "Create Zap."
Choose Squarespace as your trigger app. Select the trigger event, such as "New Form Submission" or "New Order." Connect your Squarespace account to Zapier. You'll need to grant Zapier permission to access your Squarespace data.

Next, choose ConvertKit as your action app. Select the action you want to perform, such as "Add Subscriber to Form" or "Add Subscriber to Sequence." Connect your ConvertKit account to Zapier. You'll need to provide your ConvertKit API key, which can be found in your ConvertKit account settings under "Account Info."
Step 2: Configure the Zap
Map the data from Squarespace to ConvertKit. This involves selecting the corresponding fields from Squarespace (e.g., name, email address) and matching them to the appropriate fields in ConvertKit (e.g., first name, email).
Test your Zap to ensure that data is being transferred correctly between Squarespace and ConvertKit.
Step 3: Activate the Zap
Once you've confirmed that the Zap is working correctly, activate it. The Zap will now automatically run whenever the specified trigger event occurs in Squarespace.
Method 3: Embedding ConvertKit Forms in Squarespace Lightboxes (Pop-ups)
Using ConvertKit forms in lightboxes or pop-ups can be an effective strategy for capturing attention and increasing opt-in rates. This method also uses code injection.

Step 1: Create a Form in ConvertKit (As described in Method 1)
Design and save your form as described in Method 1. Select the HTML embed code.
Step 2: Implement the Lightbox Functionality in Squarespace
This requires adding custom code to your Squarespace site. Since Squarespace does not offer built-in lightbox functionality, you'll need to use JavaScript and CSS.
First, add the following JavaScript code to your Squarespace site's footer. You can access the footer code injection area through "Settings" -> "Advanced" -> "Code Injection."
Note: The following code snippet is a basic example and might require adjustments based on your specific design and preferences. Consider using a lightbox library (e.g., Fancybox, Lightbox2) for more advanced features and easier implementation.
<script>
document.addEventListener('DOMContentLoaded', function() {
// Create the lightbox container
var lightbox = document.createElement('div');
lightbox.id = 'myLightbox';
lightbox.style.cssText = 'position: fixed; top: 0; left: 0; width: 100%; height: 100%; background-color: rgba(0, 0, 0, 0.8); display: none; justify-content: center; align-items: center; z-index: 9999;';
document.body.appendChild(lightbox);
// Create the lightbox content container
var lightboxContent = document.createElement('div');
lightboxContent.id = 'lightboxContent';
lightboxContent.style.cssText = 'background-color: #fff; padding: 20px; border-radius: 5px; max-width: 80%; max-height: 80%; overflow: auto;';
lightbox.appendChild(lightboxContent);
// Create the close button
var closeButton = document.createElement('button');
closeButton.textContent = 'Close';
closeButton.style.cssText = 'position: absolute; top: 10px; right: 10px; cursor: pointer;';
lightbox.appendChild(closeButton);
// Close the lightbox when the close button is clicked
closeButton.addEventListener('click', function() {
lightbox.style.display = 'none';
});
// Close the lightbox when clicking outside the content area
lightbox.addEventListener('click', function(event) {
if (event.target === lightbox) {
lightbox.style.display = 'none';
}
});
// Function to open the lightbox
window.openLightbox = function(content) {
lightboxContent.innerHTML = content;
lightbox.style.display = 'flex';
};
// Example usage: Open the lightbox after 5 seconds
setTimeout(function() {
openLightbox('<p>Subscribe to our newsletter!</p><div id="convertkitFormContainer"></div>');
// Inject the ConvertKit form code after the lightbox is opened.
var convertkitFormContainer = document.getElementById('convertkitFormContainer');
convertkitFormContainer.innerHTML = document.getElementById('convertkitFormCode').innerHTML;
}, 5000);
});
</script>
Next, add the following CSS code to your Squarespace site's CSS editor. You can access the CSS editor through "Design" -> "Custom CSS."

#myLightbox {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0, 0, 0, 0.8);
display: none;
justify-content: center;
align-items: center;
z-index: 9999;
}
#lightboxContent {
background-color: #fff;
padding: 20px;
border-radius: 5px;
max-width: 80%;
max-height: 80%;
overflow: auto;
}
Step 3: Embed ConvertKit Form (hidden)
Add a "Code" block to any page. This block will be used to store the ConvertKit form code, but it will be hidden from view. Paste the HTML code from ConvertKit into the "Code" block. Add the attribute style="display:none;" to hide the element.
<div id="convertkitFormCode" style="display:none;">
<!-- Your ConvertKit form HTML code goes here -->
<form action="..." method="..." ...>
...
</form>
</div>
Step 4: Trigger the Lightbox
The JavaScript code provided in Step 2 includes an example that will open the lightbox after 5 seconds using setTimeout. Adjust the timing as needed. You can also trigger the lightbox based on other events, such as when a user scrolls a certain percentage of the page or clicks a specific button. Modify the JavaScript accordingly.
Considerations and Best Practices
- Mobile Responsiveness: Ensure your forms and lightboxes are responsive and display correctly on all devices. Test thoroughly on different screen sizes.
- GDPR Compliance: Always include a clear consent checkbox and a link to your privacy policy to comply with GDPR regulations.
- A/B Testing: Experiment with different form designs, placements, and triggers to optimize your conversion rates.
- Spam Prevention: Implement reCAPTCHA or other spam prevention measures on your forms to avoid bot submissions.
- Confirmation Message: Display a clear confirmation message after a user submits the form to acknowledge their subscription.
Conclusion
Integrating ConvertKit with Squarespace is crucial for effective email marketing and lead generation. By using code injection, Zapier, or lightbox implementations, you can seamlessly capture leads and automate your email marketing workflows. Remember to prioritize mobile responsiveness, GDPR compliance, and A/B testing to maximize your results.
Key Takeaways:
- Code injection provides flexibility but requires HTML knowledge.
- Zapier offers advanced automation options.
- Lightboxes can improve opt-in rates but require custom coding.
