F.A.Q.
Which platforms does Klaviyo integrate with?
Klaviyo connects natively with the major eCommerce platforms, including Shopify, WooCommerce, Magento (now Adobe Commerce) and BigCommerce. On Shopify you install an app, on WooCommerce the official WordPress plugin and on Magento an extension. Beyond your store, you can connect Klaviyo to your CRM and to ad platforms like Facebook and Instagram, so email and ads use the same audience data.
How do you integrate Klaviyo with Shopify?
Install the official Klaviyo app from the Shopify App Store and connect it to your Klaviyo account. Customer data, purchase history and products then sync automatically. Next, build segments such as new customers, loyal customers and cart abandoners, set up email and SMS templates in your brand style, and check that you have consent for every contact. Test on a small segment first.
Which Klaviyo flows should you set up first?
Start with flows that respond to clear customer behavior: a welcome flow for new subscribers, an abandoned cart flow, and a post-purchase flow that asks for feedback or recommends complementary products. Then add a re-engagement flow for lapsed customers and, if you collect birthdays, a birthday flow. Test subject lines, content and send times to improve each flow over time.
Do you need a developer to integrate Klaviyo?
Not for a standard setup. The native integrations for Shopify, WooCommerce and Magento sync customer and product data without in-depth technical knowledge. For custom work you do need technical help, for example to connect a separate CRM, send custom events or link a headless storefront. Flatline, a Klaviyo Platinum Partner, aligns Klaviyo strategy with the Shopify build underneath so both stay in sync.
Can you send SMS with Klaviyo?
Yes. Besides email, Klaviyo lets you send SMS from the same platform and with the same customer data, in the countries where Klaviyo supports SMS. It works well for time-sensitive messages such as expiring sales, flash sales for loyal customers and shipping updates. Make sure you have explicit SMS consent under GDPR or CCPA, and keep messages short and relevant, because SMS feels more personal than email.
