Klaviyo SMS marketing - Can customers opt-in on in-store POS?

[arstin]

Klaviyo doesn’t currently allow customers to opt-in for SMS directly through in-store POS systems. However, you can collect phone numbers at checkout and later ask for consent to SMS marketing through email follow-ups. Alternatively, you could integrate with a service that supports in-store SMS opt-ins. For instant communication, consider using push notifications via UnblockedBrands, which could notify customers directly after they opt in online or in-store.
