The past quarter has been packed with product releases and it can be hard to keep up. Here’s a straightforward recap of what shipped in Q3 2025, including the updates people have asked for most often, and the rest of the improvements that might help you get more out of Klaviyo.

Highlights

These releases are huge for Klaviyo, but also a huge win for users because some were fast-tracked or born out of customer feedback, support tickets, and search data – features many of you flagged as pain points or top-of-list requests.

• AI-powered Helpdesk (Sep 25): A workspace that gives faster, more accurate resolutions while surfacing upsell opportunities. Built to reduce the back-and-forth in customer support.
   
• Customer Agent (Sep 24): A 24/7 AI assistant that can answer FAQs, recommend products, update orders and returns, and hand off to your team with context intact.
   
• Omnichannel Campaign Builder (Sep 23): One of the biggest asks—finally, you can plan and send coordinated campaigns across email, SMS, push, and WhatsApp in a single flow.
   
• WhatsApp Messaging (Sep 24): Consistently one of the most requested new channels. Klaviyo now fully supports WhatsApp, including forms, replies, and automations.
   
• Forms Dual Preview (Sep 19): No more device toggling. Preview desktop and mobile versions of forms side by side while you design.
   
• SMS State Quiet Hours (Sep 23): Compliance concerns around quiet hours came up often. Now, flows automatically respect state-specific quiet hour rules.
   
• New Navigation (Sep 9): A faster, clearer account layout, designed in response to customer searches like “where do I find…?”
