Klaviyo Integration with Shopify App Custlo — Complete Setup Guide for Shopify Merchants

The Problem with Generic Marketing

Most Shopify merchants need specific customer details that Shopify does not collect by default.Custlo solves this by allowing you to create unlimited custom fields and collect valuable customer information. With Klaviyo integration, all submitted custom field data is synced to Klaviyo as Profile Properties, helping you:

• Personalize email/SMS messages
• Segment customers better
• Run smarter automation flows
• Improve relevance and conversions

Are you struggling to send truly personalized emails to your customers?

• Limited Data: Shopify’s default customer account page only collects basic information like name and email. This isn't enough for meaningful personalization.
• Generic Campaigns: Relying on basic data means your email campaigns lack personal touches like birthdays, interests, or preferences.
• Low Engagement: Without personalization, customers engage less, conversions drop, and sales decrease.

We offer a simple, no-code solution to activate personalized email marketing in just three easy steps:

• Capture Rich Data: Use Custlo to set up custom fields and gather detailed customer information.
• Connect Instantly: Authorize the direct connection between your Klaviyo and Custlo accounts.
