How do I add a popup to my Squarespace site?+
Create a campaign in the NounDesk dashboard, then Add the script in Settings → Advanced → Code Injection → Footer. After that, every popup, banner, and form is managed from the dashboard — no further code changes.
Do I need a plugin or app for Squarespace?+
No. No third-party extension needed — Code Injection is all it takes. NounDesk is a single, framework-agnostic script.
Will NounDesk slow down my Squarespace site?+
No. The script is under 30 KB gzipped, loads asynchronously, initializes in about 100 ms, and renders inside the Shadow DOM so it never blocks rendering or conflicts with your CSS.
Can I capture emails on Squarespace?+
Yes. Add a lead-capture form to any modal, slide-in, banner, or exit-intent popup, then export submissions to CSV or forward them to your tools via signed webhooks.
