# Introduction {#introduction}

## What does it do? {#introduction-what-it-does}

Universal Messenger lets editors compose a newsletter as a normal TYPO3
page, using the site's usual content elements, and send it through the
[Universal Messenger](https://www.universal-messenger.de/) webservice.

-   A dedicated **Newsletter** page type carries the newsletter
    content and a selectable Universal Messenger channel.
-   A backend module renders a per-language preview of the newsletter and
    triggers a TEST or LIVE dispatch to Universal Messenger.
-   A console command imports the newsletter channels that are configured
    in Universal Messenger, so editors always see the current channel list
    in the page properties.
-   Fluid ViewHelpers and dedicated content elements (for example a
    personalization control structure) integrate with Universal Messenger's
    placeholder and templating conventions.
-   Shipped TypoScript renders the newsletter content with the [Foundation
    for Emails 2](https://get.foundation/emails.html) framework and
    inlines the resulting CSS, so the newsletter HTML matches what most
    email clients render correctly.
