At Klaviyo, our mission is to help businesses harness their data to power smarter digital relationships with their customers.

As you may have read in our recent post about our new integrations development framework, a significant portion of your essential data comes from external sources—other tools across your tech stack. Easily integrating these third-party systems with Klaviyo has been crucial for us and our customers since day 1.

The more data you have in Klaviyo, the stronger your personalization, segmentation, and analytics And the stronger your personalization, segmentation, and analytics, the stronger your relationships with your customers.

Klaviyo has a growing ecosystem of technology partners and developers that build with us in order to empower you to best leverage your data. In fact, we currently offer over 350 pre-built integrations, built natively and by partners, to help brands seamlessly integrate their entire tech stack without complex development or costly set-up.

As your brand gets ready for the upcoming global holiday season, we’re highlighting 5 key integrations to help you drive new customer acquisition, enhance personalization across every channel, and, as a result, boost repeat purchases. Let’s jump in.

1. TikTok

Deliver more personalized advertisements on TikTok, the leading destination for short-form mobile video. With this integration, you can drive higher conversions, attract new customers, and increase ROAS with smarter targeting on TikTok Ads Manager. Plus, you save time with dynamic syncing, so your audiences are always up to date—no more CSV exports.

Key use cases for TikTok:

• Retarget high-intent segments to drive conversions: Target segments like cart abandoners or previously engaged customers to re-engage them and drive revenue.
• Exclude unlikely-to-buy segments to save ad dollars: Exclude specific lists or segments from your ad campaigns, like recent purchasers or customers with open support tickets, to optimize your ad spend.
• Leverage lookalikes to grow your customer base: Build lookalike lists of potential new buyers based on your highest-value customers, like an RFM-based champions segment.

2. Buy with Prime

Easily sync your Buy with Prime order and customer data with your Klaviyo account to get a more complete view of each customer. With this integration, you can leverage Buy with Prime data across flows, campaigns, segmentation, and reporting. As a result, you can provide more targeted communications to the same customers in the future, further nurturing customer relationships and driving repeat purchases.

Key use cases for Buy with Prime:

• Gain a more robust unified view of every customer: With more centralized data purchase and shopping behavior about your customer, you can better leverage Klaviyo as your source of customer truth. And with our AI tools, you can more accurately make predictions about a customer’s next order date, customer lifetime value (LTV), churn risk, and more.
• Increase new conversions and acquisition: Target customers who initiated a Buy with Prime order but did not complete check-out with an abandoned cart email or SMS. Use one of Klaviyo’s advertising integrations (hello again, TikTok) to attract new customers that made similar Buy with Prime product purchases, and cross-promote other products that are eligible for Buy with Prime so you attract new customers likely to engage with your brand.
• Drive repeat purchases: Automate post-purchase flows for Buy with Prime customers, ask about their experience, cross-sell and up-sell with personalized product recommendations based on a customer’s purchase history, create a new segment of customers who purchase through Buy with Prime, and send personalized communications that acknowledge a customer’s preferred method of purchasing.

3. Recharge

Boost engagement, retention, and LTV with Recharge, a leading subscription management solution helping turn shoppers into loyal, long-time customers. With this integration, you can ensure every message to your subscribers hits home by responding to key customer lifecycle subscription events in real time—such as started check-out, started subscription, order upcoming, subscription canceled, and more.

Key use cases for Recharge:

• Drive retention with subscription flows and beautiful upcoming order reminders: Create flows with Recharge events and customize subscription emails by adding images of upcoming orders and dynamic subscription data into your emails.
• Increase average order value (AOV) with targeted cross-sells and dynamic product recommendations: Welcome customers when they start a subscription and include a one-time product cross-sell quick action link.
• Reactivate churned customers with omnichannel win-back campaigns: Offer easy-to-access custom discounts to customers who canceled their subscription in order to win them back—across email, SMS, or even to a retargeting audience on TikTok, Google, or Meta.

4. PostPilot

Make your lifecycle campaigns work harder with direct mail. PostPilot makes it easy for brands to test and add a new, effective channel to their marketing mix: direct mail. With this integration, you can drive more ROI and add a personal touch by layering in direct mail to extend your reach and get customers to convert.

Key use cases for PostPilot:

• Send postcards to non-converters: Have customers who open your welcome series or abandoned cart flows but don’t convert? Send them a postcard with a special offer (like a single-use coupon!) to get them across the finish line.
• Promote new or seasonal products: Launching a holiday campaign? Feature your products on a trifold card-a-log to get them in front of the right audience.
• Enhance personalization and customer experience: Incorporate direct mail into your marketing to reach customers on the channel they want, and even add personal touches with authentic handwritten cards.

5. Octane AI

Boost sales and increase AOV with data engaging quizzes from Octane AI, the quiz platform built for Shopify. With this integration, you can sync customer emails and data collected from Octane AI Shop Quizzes, product recommendations, or opt-in tools with Klaviyo. As a result, you can deliver deeply personalized 1:1 experiences at scale by using this data across the entire Klaviyo platform—in segmentation, flows, campaigns, reporting, and more.

Key use cases for Octane AI:

• Collect more emails and phone numbers: Leverage robust, personalized quizzes to collect customer contact information more effectively and increase subscriber counts.
• Collect more zero-party customer data: Quizzes are filled with valuable zero-party data about personal preferences and values, product matching, and more—and in Klaviyo, it’s all saved as profile properties in real time.
• Enhance personalization and product recommendations: Use this plethora of new, trustworthy zero-party data to raise the customer experience bar by creating segments, informing product recommendations, triggering flows, and building campaigns using this data.
