# Message Preview (Email)

## Introduction

Message Preview lets you review an email message before sendout.

It shows a simulated version of the email so you can quickly verify content, personalization, and visual presentation.

## What Message Preview shows

Message Preview provides different views of the same email to help you validate how the message appears under different conditions:

- A preview for a specific recipient
- An overview of all personalization variants
