How it works

How SpamShield works

On Shopify, install the app and turn on the app embed. On any other website, paste one script tag. Then every form submission is scored before it reaches your inbox.

On Shopify

1. Install the app from the Shopify App Store. You start on the Free plan.
2. Turn on the app embed. In your theme editor, switch on the SpamShield app embed. You don't need to edit theme code.
3. Run a test. Use Test Mode in the app to see how a message would be scored.
4. Review and tune. Check blocked and quarantined messages and adjust sensitivity, keywords and lists if you need to.

On any other website

1. Create a free account at spamshield.dev/register and add your site.
2. Paste one script tag from your dashboard into your pages. It finds the forms on the page, including forms added later by JavaScript.
3. Review and tune from the same dashboard.

How a message is scored

Each check adds to a spam score from 0 to 100. Instant checks (honeypot, timing, a JavaScript check) run first, then sender reputation and content checks. On paid plans, borderline messages can also be checked by AI on your own key.

What visitors see

Real visitors fill in your form as normal. There is no CAPTCHA or checkbox. When a message is blocked, the sender sees your block message. The default is "Your message could not be submitted. Please try again or contact us directly." You can change it in Settings.

What you see

Blocked and quarantined messages appear in the app with their score and the reasons. Release a quarantined message in one click, or allowlist the sender.

If SpamShield can't complete a check

If a check fails because of an error or a timeout, the form submission goes through as normal. This keeps your form working. It does not mean every completed check will be correct, so review your quarantine from time to time.
