When a member signs up for a loyalty program and consents to marketing, Stokk pushes them to your own marketing platform as a subscribed profile (email and SMS) with their program, store and customer number attached for segmentation. No more CSV exports, and the consent is captured and stored as proof.
Go to Admin → Integrations → Marketing list. Pick your provider, Klaviyo or Mailchimp, paste the API key, and enter the list / audience ID new members should join. Hit Test connection to confirm. The key is encrypted at rest. Klaviyo syncs email + SMS; Mailchimp syncs email (SMS consent is still recorded in Stokk).
For Iceland we recommend setting that Klaviyo list to double opt-in; Klaviyo then sends its own confirmation, which is the cleanest consent posture.
Open a program's settings (Loyalty → a program → settings) and under Marketing consent:
At the till, the operator enrollment form has the same opt-in to tick when a customer agrees verbally.
On a consented signup the profile is pushed immediately; a 5-minute background sync retries anything that didn't go through. In Loyalty → Applications, the Card column shows each member's Klaviyo status: ✓ Klaviyo, pending, or error (hover for the reason, with a Re-sync button to retry).
