Description

Die Klasse ermöglicht den Versand von E-Mails mit .NET über Templates. In diesen Templates können Platzhalter platziert werden, die dann dynamisch ersetzt werden.

Das spart vor allem das müßige Zusammensetzen von einzelnen Mail-Texten und ermöglicht eine einfachere Pflege über Text- oder HTML-Templates.
