Hey community! I watched the K:BOS 2026 keynote live so you didn't have to, and honestly, there's a lot to unpack. I've put together everything you actually need to know below, with my honest takes on what matters, what to try first, and what to watch out for. Grab a coffee and let's get into it.

Alongside this, Klaviyo introduced a natural-language SQL preview, renamed Marketing Analytics to Personalization, expanded Composer into a background task runner, added new language support to Customer Agent, and previewed Customer Hub expansion, Clicks to Bricks, and Compliance Hub.Jump toWhat does "headless" mean for a Klaviyo customer?
