Squarespace Waitlist Integration
Why use LaunchList with Squarespace?
Squarespace's built-in forms capture emails but offer no referral mechanics, no position leaderboards, and no fraud detection. LaunchList adds a full viral waitlist to any Squarespace page via a Code block — no design disruption, no subscription required.
What you get:
- Viral referral program — every signup gets a unique referral link that moves them up the waitlist
- Fraud detection — disposable email blocking, MX validation, and behavioral scoring on every submission
- Matches your design — the widget inherits your Squarespace styles or can be fully custom
- CSV export — download your full list any time
- Free plan — up to 100 submissions, no credit card required
Setup uses Squarespace's built-in Code Injection (for the script) and a Code block (for the widget). Takes under 5 minutes. Requires a Squarespace Business plan or higher for Code Injection access.
