Ecommerce email list cleaning

Paste one checkout or win-back address. This free check looks at syntax, the mail server, disposable domains, and role accounts such as orders@ or support@. It does not open the mailbox.

• A typo at checkout still creates a customer row you pay to mail.
• Marketplace role addresses are not shoppers and should not get a personal offer.
• Disposable inboxes inflate list size and then bounce the receipt.
