We have a project, to upload our subscriptions into Klaviyo. One subscription will be one profile in Klaviyo. And one customer (with email, address, phone) may have multiple subscriptions, and one subscription has an unique ID (number). We are planning to use this unique ID (plus a prefix) as external Id for Klaviyo profile.
Initially, I tried to upload some subscriptions, and it was good. Multiple subscriptions for one customer (one email) could be uploaded to Klaviyo, and created multiple profiles.
But later, it doesn’t work.
When I googled, it says on Klaviyo, email has to be unique. One email can only have one profile.
I am confused.
What’s the fact?
