How to Stop Form Spam on Squarespace
Squarespace form blocks are clean and easy to add — which also makes them easy for bots to target. If your Squarespace forms are collecting spam, you can layer automatic filtering on top using Squarespace’s code injection.
Why Squarespace forms attract spam
Squarespace form blocks render predictable markup on public pages. Automated tools submit to them without a human ever visiting, producing the usual SEO, link, and partnership spam in your form notifications.
Squarespace’s native spam controls are minimal, with no reputation scoring, content rules, or a review queue.
The fix: layered filtering via code injection
SpamShield scores each submission on sender reputation, content, behaviour, and optional AI, blocking spam while letting real messages through. It installs through Squarespace’s code injection, so it works across your form blocks without touching each one.
Borderline submissions are quarantined for review, and every block has a readable reason.
