There are the two parts you'd need to set something like that up - a "trigger" and a "target". I'd recommend using the HTML editor to make this edit.
You can click the HTML icon to open up the HTML view for your content and find the words you want to serve as the "trigger".
TRIGGER: This will be what you click to "jump" to the section below.
...Expanded Service Area....
you'll want to add in the link around it:
<a href="#Section1"> ...Expanded Service Area ... </a>
TARGET: For the second part, you'll want to add the "target" - this defines where you'd "jump" to. I will usually add this "target" at the top of my content, or on the bottom of the section above it because when you "jump" it'll push this section to the top of the page. If it's too far down, you might clip some of the content on top - if that's happening, just add it to the editable section above. That "target" would look something like this:
<a name="Section1"></a>
... the rest of your content here ...
The "important" pieces here are that the Trigger has a # in front of the "name", that it matches the "name" (with the exception of the #), and that it does not include spaces in the name.
If you'd like to post a piece of your newsletter code, we could put this into play for the greater good - I'd be happy to help!
