    .Link(m => $"<a href='{m.Link}'>{m.Content}</a>")
    .Title(m => $"<h1>{m.Content}</h1>")
    .SubTitle(m => $"<h2>{m.Content}</h2>")
    .Text(m => $"{m.Content}")
    .StrongText(m => $"<strong>{m.Content}</strong>")
    .UnorderedList(m => $"<ul>{m.Content}</ul>")
    .OrderedList(m => $"<ol>{m.Content}</ol>")
    .ListItem(m => $"<li>{m.Content}</li>")
    .LineBreak(m => $"</br>")
    .Button(m => @"<table class='body-action' align='center' width='100%' cellpadding='0' cellspacing='0'>
            <tr>
                <td align='center'>
                <table width='100%' border='0' cellspacing='0' cellpadding='0'>
