Klaviyo popup for Shopify

How Poppy does it
Poppy connects to Klaviyo with your private API key. Pick the list new subscribers join, and every popup submission upserts the contact — email, phone (normalised to E.164), first/last name and the source campaign. Poppy also reads Klaviyo list and segment membership, so you can target popups by it.
- ✓ Real-time, two-way: sync new subscribers and target by existing Klaviyo list/segment
- ✓ Suppress current subscribers — add a rule so anyone already in your list never sees the opt-in again
- ✓ Works across 9 popup types: email, SMS, spin-to-win, exit intent and more
Klaviyo popup — FAQ
How do I add a Klaviyo popup to Shopify?
Install Poppy, go to Integrations, connect Klaviyo with your private API key and choose a list. Build a popup in the editor, set it live, and submissions sync to Klaviyo in real time.
Can I stop showing the popup to existing Klaviyo subscribers?
Yes. Add a targeting rule that excludes anyone already in a chosen Klaviyo list, so loyal subscribers aren't asked to sign up again.
Does it sync phone numbers for Klaviyo SMS?
Yes. Phone numbers are formatted to E.164 before syncing so your Klaviyo SMS flows receive clean, diallable numbers (subject to Klaviyo's supported countries).
