Connect Klaviyo to the platforms you already sell with

Klaviyo keeps doing what it is best at. Plandalf handles the offer, checkout, buyer fields, payment context, invoice data, and post-purchase events that every other app needs.

Klaviyo is an ecommerce-focused email and SMS platform with a powerful Flow builder that supports webhook actions natively. For promos, the standard pattern is embedding a countdown GIF into a flow email and enrolling subscribers from a List-triggered or Metric-triggered flow. ## What Plandalf does here - **Per-recipient countdown** — Klaviyo's `{{ person.email }}` merge tag passes straight into the `<img src>` query string, so each subscriber sees their own deadline. - **Flow-driven enrolment** — Flows include a native Webhook action, allowing direct POSTs to the promo's catch URL without middleware.
