Only import people who have given your store lawful consent to receive marketing. In practice, that means real customers and subscribers of your own Shopify store.
You can import
Customers and subscribers from your own Shopify store who agreed to marketing
People who signed up through your own forms, pop-ups or checkout
Subscribers from your previous email tool who opted in to your store
You can't import
Bought, rented or shared lists
Scraped addresses, or contacts from lead databases
Cold B2B prospect lists, even if the addresses are public work emails
Another business's customers, even a partner's
Why it matters
Emailing people who never opted in leads to bounces and spam complaints. That damages your own sending domain, and in many countries it is also against the law.
What happens if a list doesn't qualify
We may pause sending or block the account, and ask you to delete the list.
Not sure about a list?
If you are not sure a list qualifies, don't import it.
