Klaviyo January Updates

Here's your monthly roundup of all the shiniest new products and updates from the world of Klaviyo.

Smarter send times

Timing can make or break a campaign. Even the best message underperforms if it lands at the wrong moment. That’s why smarter send times focus on when each individual is most likely to engage, not just when your audience averages out.

Send when each subscriber is most likely to convert

Personalised Send Time automatically delivers each campaign at the predicted best moment for every recipient, all within a delivery window you control. You choose the send date and time range, and Klaviyo handles the rest; sending messages in each recipient’s local time when they’re most likely to open, click, and convert.

Why it’s different

Unlike Smart Send Time, which selects one optimal send time for your entire audience, Personalised Send Time works at the profile level. That means:

• Different subscribers receive the same campaign at different times

• Delivery is optimised for individual behaviour, not averages

• Engagement and conversion rates improve without extra effort

By meeting subscribers at the right moment instead of blasting everyone at once, Personalised Send Time helps your campaigns feel more relevant and perform better by default.

Video across every mobile channel

Video drives attention, but using it in mobile messaging often comes with friction. File limits, hosting issues, and channel-specific requirements make it harder than it should be for marketers to move fast.

With Klaviyo, adding video to mobile messages is simple and reliable. Upload a video once, then attach it to campaigns across WhatsApp, RCS, MMS, and Push notifications (push coming soon) with a single click. Klaviyo automatically optimises delivery, ensures compatibility across devices, and tracks performance - no extra setup required.

How it works

• Upload a video to the Media Library or directly in the message editor

• Add it to WhatsApp, RCS, MMS, or Push campaigns just like an image

• Klaviyo handles optimisation, delivery, and performance tracking

This removes the technical barriers to video, letting marketers use high-impact creative everywhere their audience is, without changing workflows or worrying about limitations.

A cleaner, more connected campaign builder

Running effective campaigns requires more than sending the same message everywhere. Marketers need stronger targeting, clearer insights, and automated audience logic; without relying on manual workarounds.

Audience filters let you target specific customer sub-segments for each message in your campaign, so every subscriber gets the right message, at the right time, on the right channel. Filters are calculated immediately before send, using each profile’s most recent behaviour and attributes to ensure accuracy.

To refine targeting even further, you can combine conditions using:

• AND logic to require all conditions

• OR logic to require at least one condition

Within a single omnichannel campaign, you can:

• Tailor audiences per message using filters

• Automatically remove converters with exit conditions

• Compare channel performance through unified reporting

• Use channel affinity to send messages where each subscriber engages most

This creates a cleaner, more connected campaign experience, where targeting, delivery and insights work together to drive more personalised engagement over time.

Automatic localisation for global shoppers

Global brands need localisation at scale, without managing multiple catalogues or duplicating campaigns. Klaviyo’s integration with Shopify Markets makes this possible by automatically adapting content for each customer’s region.

With a single campaign, customers see the correct language, currency, availability, and localised URLs based on their Shopify Market, with no manual work required.

How it works

When Shopify Markets is enabled in Klaviyo, locale data (language, region, and pricing) syncs from Shopify into Klaviyo. This allows you to personalise emails and flows automatically, ensuring every message feels personalised to the receiver.

Key capabilities

• Dynamic Product Blocks: Automatically match product language and pricing to each customer’s location.

• Static Product Blocks: Select a locale-aware catalogue for specific regions.

• Segmentation: Target customers by country or language using locale properties.

• Localised Flows: Personalise automated messages using synced market data.
