Totally fine to keep the email, just don’t put it in the Lightning memo. Flow: Woo collects email and address, plugin makes an invoice with memo = Order #, payment marks the order paid, then you import to Pirate Ship from Woo or via CSV and it carries the email for tracking. That’s how we keep PII in the store layer, not the payment layer at Masters of The Lair. Do you import from Woo or upload CSV today?
