When to block an email
Block an email when you know the customer is a problem. It follows the person, not their location, so it works when their address or country changes.
Good reasons to block an email
- A customer keeps filing chargebacks or abusing returns. You have seen it more than once, on the same email.
- An order was clearly fraud. Block the email so the same buyer cannot simply try again.
- Orders keep coming from a throwaway email service. Block the whole domain, such as
@tempmail.com. - Someone keeps creating similar addresses. Block the series with a pattern, such as
hrysy*@mail.com.
When not to block an email
- The domain is one real customers use. Blocking
@gmail.comwould stop everyone with a Gmail address. Block a whole domain only when you are sure it is a throwaway service. - A customer had one dispute. It can be an honest mistake. Decide on the order first. See When to cancel, hold or clear a risky order.
- The trouble is anonymous. Visitors who are not logged in are not affected by a block on the storefront. For them, look at bots or IP addresses.
What an email block does
- On your storefront, a blocked customer who logs in sees the block page. Guest visitors are not affected.
- At checkout, blocked emails cannot complete checkout, once you turn on Block at checkout and activate the rule in Shopify.
A determined person can use a new email, so an email block works best alongside your other rules. Email rules depend on your plan. To set one up, see How to block an email or a domain.
