It looks fine around, except in Outlook 2010. First off, the ads between the stories (Better Homes and Gardens and Home Health Care) don't have any space between them. I used vspace to create a space, and it's even one of the tools in the editor, so I assumed it would be widely supported.
2, there is a margin-bottom on the tables that don't have an ad below them, so that there is space between them. Again not working in Outlook 2010.
Now I can deal with those two problems because I'm sure I can add a blank <p> between everything to get the effect. The big problem is in Outlook 2010 I get a weird gap in the story headline:
If anyone would like me to send a test to their email to see if it happens the same way for them, I'd be glad to do so.
