Drive more email revenue
Send hyper-relevant campaigns based on real-time audience behaviour, historical data, predictions, and beyond.

No coding required
Build precise audiences in minutes. Define exactly who you want to reach with drag-and-drop tools that let you get as specific as you want.
Make every campaign feel more personal
Ultra-relevant messages are the real moneymakers—and Klaviyo makes sending them a snap. Break your email contact list down into super-focused audiences (also known as segments) so you can target exactly the right people with more influential, tailored email content.
Build segments based on any customer data, including:
- Real-time behaviour
- Any historical data, even dating back to the launch of your store
- Built-in predictions about future behaviour
- Any other data imported from your ecommerce store, integrated platforms, or API

Build your ideal audiences
List behavioural segmentation
Segment based on any activity tracked by Klaviyo, including real-time events from your marketing website, ecommerce store, marketing software, and other integrated tools and platforms.
Custom properties and attributes
Filter according to any kind of data you’ve imported from other platforms, gathered via custom forms, or entered manually to round out customer profiles.
Location
Define segments based on proximity to a selected postal and ZIP code in AU, the US, EU, or Canada. For UK post codes, we support filtering by outward code.
EU residence (GDPR)
Easily exclude EU contacts from a given segment. This option is especially helpful if you haven’t collected GDPR compliance consent.
Other subscriber lists
Combine two or more lists to reach a new audience, or create a segment of a specific list to follow best practices when sending campaigns.
Suppressed contacts
Follow best practices by excluding suppressed contacts from a given segment. This creates a more accurate view of who you can actually reach.
SMS consent
If you’ve activated Klaviyo SMS, you can filter by SMS consent to avoid texting the wrong contacts, or use email and other channels to encourage SMS subscriptions.
Predictive analytics
Filter audiences based on predicted Customer Lifetime Value, predicted gender, predicted date of next purchase, and more.
Go ahead, get super-specific
Hone each segment with as many conditions as you need. Want to target an audience of female dog owners who live in Brighton and are likely to make another purchase within the next 10 days? Now you can.
With real-time tracking, predictive analytics, and flexible conditions, you can finally target valuable segments like:
- Product-specific audiences
- Full-price buyers
- Unengaged customers
- Last year’s Cyber Monday shoppers
- Shoppers who’ve viewed the same product 5+ times without purchasing
- Customers who only make purchases with coupons
- Customers who only buy on certain days
- Customers who are most likely to buy within the next 10 days
- VIP customers (frequent shoppers or big spenders)
