Stoplist refuses checkout to buyers you have blocked. Block the buyer of an order from the order page, add an email, phone or address by hand, or have Stoplist block the buyer of every order that gets a Shopify Payments chargeback. A blocked buyer is stopped at checkout, before paying, express checkouts included, and sees your message. Emails, phones and addresses match however they are typed. Stoplist keeps a one-way code of each detail, not the detail itself.
