Frequently Asked Questions

Common questions about Stackedboost Email Guard - Block Disposable & Fake Emails for WooCommerce

No. The free version performs all checks locally on your own server using bundled lists. Nothing is sent to any external service. There is no telemetry, no analytics and no licence check in the free version. The only outbound request the plugin can make is to the Stackedboost API, and only if you deliberately enter a Pro licence key to activate it.

Yes. Email Guard protects the WooCommerce checkout and account registration. It does not touch WordPress core registration or comments, so if you want to block disposable email on a site without a shop, this is not the plugin for it.

Yes. Email Guard validates both the classic (shortcode) checkout and the newer Cart/Checkout blocks (Store API). On the block checkout, a blocked email stops the order when "Place order" is clicked and the message appears in the block's own error state. This is worth checking on any email plugin you evaluate. A plugin that only hooks the classic checkout does nothing at all on a block-based store, and it fails silently, which is the worst way to fail.

The bundled list contains disposable email and temporary email providers only, and the typo map covers near-certain mistakes. If a real customer is ever refused anyway, add their domain to the allow list on the settings screen: it overrules everything, including the bundled list, so you never have to switch protection off to let one person through.

Add their domain to "Always allow these domains" on the settings screen. The allow list is checked first, before every other rule, so the customer is through immediately and permanently. If you want to understand why it happened first, paste the address into the tester on the same screen. It will tell you which of the four checks refused it, so you know whether it was the bundled list, your own blocklist or the typo map.

Yes. An address at mail.example.com is refused if example.com is on any list, which is how throwaway email providers usually hand out addresses. The same applies to your custom blocklist: adding competitor.com also covers orders.competitor.com.

Yes. Put their domain in the custom blocklist, one per line. It is checked on every order, it covers their subdomains automatically, and it takes precedence over everything except your allow list.

In practice they are the same thing under different names, and this plugin treats them identically. A disposable email address, a temporary email address and a throwaway email address all describe an inbox that is meant to be abandoned: usually free, usually requiring no registration, and usually dead within minutes or hours. You will also see "temp mail", which is the same idea and is the brand name of several of the larger providers.

Neither is blocked, and neither should be. A catch-all domain accepts mail to any address at that domain. Plenty of legitimate small businesses run one. Blocking catch-alls would refuse real customers in volume. Plus addressing (name+shop@gmail.com) is a normal, supported feature of the major providers, used by people who want to filter their own mail. It is not disposable, and refusing it annoys exactly the sort of organised customer you want.

The list is bundled with the plugin, so it updates when the plugin updates. It went from about 50 domains to over 8,200 in version 1.2.0. A bundled list is a deliberate trade. It never phones home, never leaks a customer address, and works if your server has no outbound access, but it is a snapshot rather than a live feed. No blocklist is complete, and anyone who says otherwise is selling something: disposable providers register new domains constantly. If the tail of newly registered domains matters to your shop, that is what the DNS and MX checks in Pro are for.
