0 on bottom email

Hi guys,

I use this in the body of the mail:

{title}
{content_post}

Then when I receive the mail, a 0 is placed under the content text, like so:

Title
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor.
0

Does anyone know why? and how I can remove it? 🙂

Thanks.
