About Unstack

You're already using Klaviyo to create more personal customer experiences with your email and SMS campaigns. Now you can bring that same level of personalization into the on-site experience with Unstack.

Unstack is deeply integrated with Shopify and Klaviyo, empowering marketing teams and agencies to quickly create dedicated shoppable landing pages for every touchpoint in the customer journey.

Take your pages even further by setting up rules that determine which content to show users based on their actions and data. For example, if someone has viewed a product multiple times but hasn't added to cart, you can set a rule to show a specific offer that nudges them to purchase, or remind them about your shipping and return policies.

How to start using this integration in minutes:

  1. Install Untack in the Shopify store (2 minutes)
  2. Enable the Klaviyo integration in Unstack (2 minutes)
  3. Grab a pre-built landing page template (5 minutes)
  4. Set your personalization rules (5 minutes)
I'm so glad I found Unstack! I wanted to test landing pages quickly without any coding or graphic design experience required. My first landing page already boosted my conversion rate by 250%. So excited to continue making more utilizing their template library. The team is also extremely helpful whenever I have any questions. Highly recommend!
