The "invisibleIntroduction" is the text used for short preview
of the email before the user opens it (50 characters max). Sometimes,
you do not want to show this message depending on your design but this
text is highly recommended.
You do not have to worry if it is hidden, the next <td> will automatically
center and apply to the width 100% and also shrink to 50% if the first <td>
is visible.
