How to enable the Klaviyo Integration API
From Spiffy Stores Knowledge Base
Klaviyo is an email marketing platform that can be integrated directly into your Spiffy Store to provide specifically targeted email and SMS messages to your customers.
Like most other email marketing platforms, Klaviyo (https://www.klaviyo.com) provides its customers with ways to create and send emails and SMS messages to specific lists of customers or potential customers. It manages the delivery and list maintenance for customers to opt in and out of this sort of marketing communication.
In addition to these basic functions, Klaviyo also provides an analytics function that is directly integrated into your store. These analytics functions allow you, as a store owner, to track the viewing and purchasing behaviour of customers who have opted-in to receive your marketing communications. These analytics functions enable you to tailor marketing communications to potential purchasers of specific types of products, such as offering special deals using coupon codes. The analytics can also detect actions such as abandoned carts or incomplete checkouts, and trigger follow-up communications to try to encourage the customer to complete the purchase.
