Yes, you can add a pop-up in Squarespace, and it's a great way to engage with visitors, capture leads, promote offers, or provide important information. Squarespace offers built-in functionality for creating pop-ups, particularly through its integrated marketing tools. Here’s a detailed guide on how to add a pop-up in Squarespace:

Using the Built-In Promotional Pop-Ups

1. Login to Your Squarespace Account: Go to Squarespace and log in to your account.

2. Navigate to the Correct Website: If you have multiple websites, ensure you are working on the correct one where you want to add the pop-up.

3. Access the Marketing Menu:

   • From the home menu, click on Marketing.
   • Click on Promotional Pop-Up. This will bring up the settings for creating a pop-up.

4. Customize Your Pop-Up Content:

   • Content:
     • Enter the Headline, Description/Body text, and CTA (Call-to-Action Button).
     • You can choose whether to link the button to another page, product, file, email address, phone number, and more.
   • Form:
     • You have the option to add a form block to capture email addresses. This can be connected to mailing lists or even integrated with services like Mailchimp.
   • Images:
     • Add images to make the pop-up more engaging. You can upload images from your computer or select them from an existing library.

5. Design Your Pop-Up:

   • Layout:
     • Choose a layout for your pop-up from the available templates. Squarespace offers several layout styles that you can pick based on your design aesthetic.
   • Style:
     • Adjust the colors, fonts, button styles, and more to align with your brand’s visual identity.

6. Configure Display Options:

   • You can specify when the pop-up should appear:
     • On the first visit.
     • After a certain amount of time (e.g., 10 seconds after page load).
     • When a visitor scrolls down the page.
   • Frequency:
     • Set how often the pop-up should appear for the same visitor (e.g., once per session, once a day).

7. Enable and Test the Pop-Up:

   • Once you’ve customized and configured everything, toggle the switch to enable the pop-up.
   • Preview the pop-up to ensure it works and looks great on both desktop and mobile devices.

Using Third-Party Services

While the built-in promotional pop-ups in Squarespace are quite flexible, you might want more advanced features or integrations. In such cases, using third-party services can be beneficial.

1. Choose a Pop-Up Service: Popular services include OptinMonster, Sumo, and Privy.
2. Sign Up and Create a Pop-Up: Follow the service’s process to design and configure your pop-up.
3. Integrate with Squarespace:
   • Most services will provide you with a code snippet.
   • In your Squarespace site, go to Settings > Advanced > Code Injection.
   • Paste the code snippet in the Header or Footer section, depending on the service’s instructions.
4. Customize and Test: Ensure the third-party pop-up matches your site’s style and test its functionality.

Considerations and Limitations

• Mobile Responsiveness: Ensure that your pop-up is mobile-friendly. Some users might have negative experiences with pop-ups on mobile devices if they're not well-designed.
• User Experience: Avoid intrusive pop-ups. They should enhance the user experience, not detract from it.
• Compliance: If collecting emails or other personal data, make sure you comply with regulations like GDPR. Include a clear privacy statement.
• Performance: Multiple or heavy pop-ups might affect your site’s loading speed. Test to ensure they don’t impact performance significantly.

By following these steps, you can effectively add and customize a pop-up on your Squarespace website, enhancing user engagement and achieving specific marketing goals.
