# Message Creation: Configuration (Email)

## Overview

The **Configuration for Sendout** window allows you to define the key settings for your email message before sending it. This step is identical for both CMS and HTML emails.

In this step, you select the recipient group, configure delivery options, and personalize your message setup.

For a conceptual overview of email message types and the overall email creation workflow, see the [Email Channel Basics](/v1/docs/email-channel-system-basics).
