Stackedboost Email Guard for WooCommerce
·
Block disposable, mistyped, and blocklisted email addresses at WooCommerce checkout — before the order is placed.
Bad email addresses cause failed deliveries, chargebacks, fake accounts, and support tickets. Email Guard checks the customer’s email at checkout and stops the risky ones before the order goes through — all locally, with no account required.
Free version (this plugin):
- Blocks known disposable and temp-mail domains at checkout
- Catches common typos and suggests the correct domain («Did you mean gmail.com?»)
- Enforces your own custom domain blocklist
- Also validates email on account registration
- A dashboard showing what it actually caught — counts, corrected typos and blocked domains
- 100% local — no external service, no account, no data leaves your site
Email Guard Pro (optional, from https://stackedboost.com/woocommerce/stackedboost-email-guard/):
- 120,000+ disposable-domain list, updated continuously
- DNS / MX deep scan to catch non-deliverable domains
- Post-order risk scoring, order tagging, and instant alerts
- Hosted risk dashboard
Pro is a separate add-on from Stackedboost and is not required to use the free version. Everything listed above under the free version keeps working whether or not you ever buy it.
