Hey @get-pozio,
Since it sounds like you may potentially be using Klaviyo with a Shopify platform, I would suggest taking a look at both the Reviewing Your Shopify Data and How to Integrate with Shopify Help Center article which will detail the types of data that get synced to Klaviyo by default.
The default types of data that would be synced to Klaviyo from Shopify are:
- Email, First and Last Name, City, State/Region, Zip Code, Country, Phone Number: These built-in Klaviyo fields are automatically populated with all available data from Shopify
- Accepts Marketing: Whether or not a customer has opted-in to receive marketing, e.g., True/False
- Shopify Tags: Any custom tags assigned to that customer in Shopify, e.g., Wholesale or VIP
In addition, should you need more information or fields to be synced to Klaviyo, you can also leverage Klaviyo’s flexible API to push this information to tag your contact. You can find more details on Klaviyo’s API from the Getting Started with Klaviyo APIs and Track and Identify API Reference Help Center article.
