Adding URLs to Subscribe2 template causes Msg. Substitutions to Disappear

I’ve tried to customize the Subscribe2 email notification template to add information for my subscribers. I’ve added a URL informing them how to unsubscribe & URLs telling them how to subscribe to my blog via Feedblitz.

I notice that adding URL’s to the template has caused weirdness within the actual e mail msg. in that some parts of it disappear. For example, in the template below, the MYNAME & EMAIL “message substitutions” do not display in the email msg.

Is it possible that the template is not meant to have URLs within it? Is there any way to use URL’s properly so they don’t affect the rest of the content of the notifcation msg.?

Here’s my current template:

BLOGNAME has posted a new item, ‘TITLE’
POST

I apologize if you ever receive more than one copy of this notice. The plugin is slightly buggy. An alternative that guarantees a single daily e-mail notice is Feedblitz:
