Add default text into email template before {EMAIL_BODY}

Hi,

I created our own email template.
All of our newsletters start with the same text at the top of the newsletter. I tried to put the text into the template, so we don't have to put it in each time.

When opening the template within the plugin it's displaying the added text okay. But when there is text entered within the plugin into the content the 'hard-coded' text disappears...

I've put in the text like this into the template:

<td class="email_content" data-builder="body_color">
						<div data-builder="email_content">
       Hi! This text is added at the beginning of the newsletter, but disappears when the content is edited into the real-time editor!
							{EMAIL_BODY}
						</div>
					</td>

What can I do to get this working?
