Why it matters

Your emails are frozen at send. Unfreeze them.

Klaviyo is great at sending, but a normal email block bakes in content at send time — so by the time someone opens it, prices, stock, and the best recommendation may have changed, and every recipient sees the same thing.

Personyze fixes that with open-time personalization. Paste one Personyze HTML block into your Klaviyo template and each recipient sees recommendations chosen for them, rendered live at the moment of open — with an API/webhook path for pushing blocks or triggering sends.

What you can do

What Personyze + Klaviyo unlocks

Open-time rendering

Recommendations and content render the moment each email is opened — so every Klaviyo send shows live inventory, prices, and the latest picks, not stale send-time content.

One snippet, any template

Paste a single Personyze HTML block into your Klaviyo template once. It works in newsletters, transactional emails, receipts, and drip campaigns alike.

1:1 personalized recommendations

Each recipient sees products or content chosen for them from a 360° profile — behavior, history, and CRM/CDP data — matched by their email address.

API & webhook triggers

Beyond embed code, Personyze can push personalized blocks into Klaviyo via API, or trigger Klaviyo sends with webhooks for behavior-based campaigns.

How it works

Design your email block in PersonyzeUse the Get-Code email recommendation wizard to design a product or content recommendation block that matches your brand.

Copy the HTML snippetPersonyze generates an HTML snippet for the block — copy it from the wizard.

Paste it into KlaviyoIn Klaviyo’s template editor, add a Text/HTML block, switch to source view, and paste the Personyze snippet (Klaviyo uses double-curly-brace templating for the email).

Map the recipient emailSet Klaviyo to populate the recipient email into the snippet’s email parameter (e.g. {{ email }}) so Personyze can personalize per recipient — then send as usual.

FAQ

Common questions

How does Personyze work with Klaviyo?

You design a recommendation block in Personyze, copy its HTML snippet, and paste it into your Klaviyo template. When a recipient opens the email, Personyze renders personalized content live — no per-send setup.

Where do I paste the snippet in Klaviyo?

In Klaviyo, add an HTML block (or the source view of a text block) and paste the Personyze snippet; use {{ email }} for the recipient address.

How are recipients personalized?

Map your Klaviyo email merge tag (e.g. {{ email }}) into the snippet’s email parameter. Personyze matches that email to the visitor’s profile; known recipients get 1:1 recommendations, and there’s a smart fallback for unknown ones.

Can Personyze trigger or push into Klaviyo?

Yes. Besides embed code, Personyze can push personalized HTML blocks into Klaviyo via API/webhook, and trigger sends based on on-site behavior.
