Kudos to all involved coders who put her love and energy in it. Without her, this extension would not exist.

Here comes a brief explanation of what each package is used for:

## friendsoftypo3/tt-address {#friendsoftypo3-tt-address}

Store mail recipients

## friendsoftypo3/jumpurl {#friendsoftypo3-jumpurl}

Used for click tracking

## typo3/cms-redirects {#typo3-cms-redirects}

Used for redirects of shorted links in plain text mails

## scssphp/scssphp {#scssphp-scssphp}

This package transpiles scss files to css, which makes it possible to use the scss files of foundation mail and change there values (colors, dimensions) using typoscript constants.
I had to modify the original scss from foundation a little, because the scssphp package could currently not handle sass modules like math, which were used on some places.
See [https://github.com/scssphp/scssphp/issues/421](https://github.com/scssphp/scssphp/issues/421) for more information. Basically, I just replaced all `math.div()` with `/`.

## pelago/emogrifier {#pelago-emogrifier}

This package is needed to convert all css to inline styles, which is unfortunately necessary for outlook and co.

## league/html-to-markdown {#league-html-to-markdown}

This package is used to convert an html mail to a plain text (markdown) version using a middleware, just by adding `?plain=1` to the url.
It has the ability to add own converters, which is used by this extension to handle the mail boundaries, which wrapped around every content element.

## masterminds/html5 {#masterminds-html5}

This package is used on several places to extract specific parts of a mail (e.g. links, images, special data attributes).

## ddeboer/imap {#ddeboer-imap}

This package is used by the AnalyzeBounceMailCommand to read the mail account of returned mails.
