What Is Klaviyo?

Klaviyo is a powerful email marketing platform designed to help businesses of all sizes drive growth through targeted and personalised marketing campaigns. With Klaviyo, businesses can easily create, automate, and optimise email campaigns based on customer behaviour, preferences, and interactions. By leveraging advanced segmentation and automation tools, Klaviyo allows businesses to deliver highly relevant and timely messages to their audience, increasing engagement and conversions. Furthermore, Klaviyo provides robust analytics and reporting features, allowing businesses to track the performance of their campaigns in real-time and gain actionable insights to continually improve their marketing strategies.

The API is used to connect websites and apps up behind the scenes, for example, automatically sending user data from a website to subscribe to a newsletter. Updating the Klaviyo API to the latest version is crucial for ensuring optimal performance, security, and access to the latest features and enhancements. By staying current with the latest version, businesses can leverage new functionalities, improve integration capabilities, and maintain compatibility with evolving technologies. This particular update means breaking changes – anyone still using the old API after this date will simply cease to work.
