Messy Text?

I wrote an Irritable Mother Newsletter this weekend, and when I sent myself a 'test copy' it didn't look much like the copy I had created. The font wasn't the same, and the text changed sizes randomly. I tried to figure it out by looking at the HTML code - Yeah, as if I could understand that stuff! - to no avail.
So then I started to wonder if it was just the way my email was reciving the message. And I decided to go ahead and send it out.
If you're reading this, it's probably because your text was messy and you clicked on the link about messy text. My apologies! I pray the message came through in spite of the mess.
