Tracy, Sometimes it’s the terminology that you’re unfamiliar with that makes the process difficult to understand, but the process itself is actually easy to accomplish.
The menu that appeared on the left side of your screen that holds your working tools is called a toolbox. The 8th icon down, on the right side, is the letter "T." That is your text tool. Click on it to activate it.
Go to the text within your e-mail, highlight it and copy it to your internal clipboard. (I’m assuming you know how to highlight text, and then Ctrl C will put it on the clipboard.) Now move into Photoshop and open a new blank document, set your preferences for your new document, being sure "background contents" is set for "Transparent," so you’ll have a transparent background. Click OK.
Your new document will open, as will a layers palette on the right side of your screen. Your layers palette will show this new layer you’ve just created. (If your new layer is titled background, double click it and change the name to whatever you want.) If the palette doesn’t open, go to the top tool bar and click Window/Layers (F7).
Now, on the lower edge of your layers palette, there are two squares overlaying each other. Clicking on it will add another layer to your palette. Drag this new layer below your first. Add a layer color to this new layer, so you can see your text above it, once you’ve written it. Layer/New Fill Layer/Solid Color (pick medium gray).
From your tool bar (I identified that for you when we began.) Click on letter "T" to activate it. This is your text tool. Move your cursor into your document (on the transparent layer), click, then paste your text (from the internal clip board where you stored it earlier) by clicking Crtl V.
Although this moves your text into your freshly made document, it won’t carry the original formatting. You’ll need to format it manually. Your Font style and pitch (sizing) controls, located in the top tool bar, will only appear when the "T" text tool is activated.
If you hold you cursor down and move it across the page forming a box, before you add the text, your text will be constrained within the box. Adjust the box size by dragging the corner boxes.
You wouldn’t normally need this many layers, as the text layer automatically creates its own layer, but I wanted you to see the mechanics of making and moving layers around. Clicking on the eyes (at the side of each layer) will deactivate that layer (turn that layer off), and it will not appear in your document.
I suggest you go to youtube.com and watch the videos by Photoshop Mama <
http://www.youtube.com/profile_videos?user=photoshopmama> Watch them all (even if you don’t think you’re interested in doing what she’s doing, as it will teach you techniques you can use in other ways) over and over until you can duplicate the techniques!
You can open your Photoshop and run the video at the same time, stopping when you need to, or backing up to see it again; all while you’re trying the technique yourself. You will learn fundamentals that will help you understand what’s happening in Photoshop. Be sure to watch the watercolor videos, I think that’s the one she shows how to make a watermark.
