Unsubscribe with Shopify
You can unsubscribe a contact in Shopify from the Shopify admin by editing their Email Marketing status.
Learn more in the Shopify article Email subscriber list management.
After you unsubscribe a contact in the Shopify admin, when the next sync happens, we add all newly subscribed contacts to your lists and remove any unsubscribed ones.
Unsubscribing contacts in Shopify only removes the contact from the Subscribers list and doesn't add them to the Marketing suppression list. For this reason, the unsubscribed contact's details might remain in Marketing.
To avoid accidentally sending to an unsubscribed contact, only send campaigns to Shopify contacts using the Subscribers list.
Unsubscribe from Marketing
There are various ways to unsubscribe or suppress a contact in Marketing:
The contact unsubscribes from within a campaign.
The contact's email address has previously hard bounced.
You add the contact's email address manually to the suppression list.
You manually unsubscribe the contact.
You add the contact's domain manually to the suppression list.
When a contact unsubscribes through Marketing, this action does not update their marketing status in Shopify automatically. The contact still remains subscribed in Shopify via the standard, 1-way sync.
The only way to push this update back from Marketing to Shopify is to enable the Two-way sync.
Two-way sync
If you're using two-way sync, then unsubscribes can happen both ways. When you unsubscribe or subscribe a Shopify contact in Marketing, then the contact's accepts_marketing status is updated with the next sync.
