# Klaviyo

Klaviyo is a marketing automation platform for email and SMS. Sesami and Klaviyo are strategic partners, and you can send Sesami booking events into Klaviyo to power confirmations, reminders, and follow-ups.

## What You Can Do

* **Appointment confirmations** — email or SMS the moment a booking is made
* **Appointment reminders** — 24 hours before, 1 hour before, or custom timing
* **Rescheduling & cancellation notices** — keep customers informed of changes
* **Post-appointment flows** — review requests, rebook offers, loyalty rewards
* **Customer segmentation** — tag customers who booked, target by service, etc.

## How It Works

Sesami sends booking events to Klaviyo via **Sesami Flows**. Each event (appointment created, rescheduled, canceled, completed, reminder) carries rich data — service, time, resource, customer management link, and more — that you can use in Klaviyo email and SMS templates.

## Setup

The full setup guide — including Flow presets, Klaviyo API key setup, and the complete list of available event properties — is here:

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.sesami.co/apps-integrations/klaviyo.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
