How to Connect Funnelish to Klaviyo for Email Marketing

Why Funnelish + Klaviyo Is a Powerful Combination

Funnelish handles the front-end of your ecommerce funnel — the landing pages, checkout, and upsells. But what happens after the purchase? That's where Klaviyo comes in. Klaviyo is the leading email marketing platform for ecommerce, and connecting it to Funnelish allows you to automatically trigger post-purchase email flows, abandoned checkout sequences, and promotional campaigns for every customer who buys through your funnel.

What the Funnelish-Klaviyo Integration Does

• Automatically adds new customers to your Klaviyo lists after purchase
• Triggers post-purchase email flows (thank you, review request, reorder reminder)
• Syncs customer data including name, email, product purchased, and order value
• Enables abandoned checkout email sequences for customers who started checkout but didn't complete it
• Allows you to segment customers based on which funnel they converted on

How to Connect Funnelish to Klaviyo

Step 1 — Get Your Klaviyo API Key

Log into your Klaviyo account and go to Account → Settings → API Keys. Click Create Private API Key and give it a name like "Funnelish Integration". Copy the API key — you'll need it in the next step.

Step 2 — Add Klaviyo Integration in Funnelish

Log into Funnelish and go to the funnel you want to connect. Navigate to the Integrations section inside the funnel settings. Find Klaviyo in the integrations list and click Connect.

Step 3 — Enter Your API Key

Paste your Klaviyo Private API key into the connection field in Funnelish and click Save. Funnelish will verify the connection and confirm it's active.

Step 4 — Select Your Klaviyo List

Once connected, choose which Klaviyo list new customers should be added to. You can create a specific list for Funnelish customers (e.g. "Funnelish Buyers") or add them to an existing list. Using a separate list makes it easy to segment Funnelish customers for targeted campaigns.

Step 5 — Map Customer Data Fields

Configure which customer data fields from Funnelish should sync to Klaviyo — first name, last name, email, phone number, product purchased, and order value. The more data you sync, the more personalized your Klaviyo emails can be.

Step 6 — Set Up Klaviyo Flows

In Klaviyo, create the email flows that will trigger for your Funnelish customers. Essential flows include:

• Post-purchase flow — Thank you email, product tips, review request (send 3–7 days after purchase)
• Abandoned checkout flow — 3-email sequence for customers who started checkout but didn't buy (send at 1 hour, 24 hours, and 72 hours)
• Win-back flow — Re-engage customers who haven't bought in 60–90 days

Tips for Maximizing the Funnelish-Klaviyo Integration

• Personalize every email with the customer's first name and product name
• Include a product image in your post-purchase emails to reinforce the buying decision
• Send the review request email 7–10 days after expected delivery
• Use Klaviyo's segmentation to send different campaigns to customers who accepted vs declined upsells
