I have to design a html newsletter my company sends out. I did it in css, but now none of the clients work with css. So i need to do it with tables and inline styles.

Any other information any of you can provide. The width of the table is 720 width.

Im a little rusty in my tables now. I did the design, but its pretty complex. Using photoshop i sliced most of the images, am i going the right away?

What other tips do you have for designing html emails?

Not sure I understand what you mean - your clients don't work with CSS. There's no reason you can't design a newsletter with in-line css.

I have to do email layouts for the company I work for. It is unfortunate, but most email clients live back in the '90s and can't handle external stylesheets. A lot of clients can only handle minimal CSS and some can't even handle any CSS at all.
It sounds like you are going about it the correct. way. I usually get the graphics looking like I want in Photoshop, then slice it up. Then I let photoshop create the tables (export html and images). But you might want to go in and look at the code that photoshop made and clean it up a bit. You might also be able to set some table cells to where they display the image as a background, so you can put actual text on top. The problem with that is not all email clients will display the text the same way. You can use some inline styles, but don't rely on them too much. Most clients can handle inline styles, but you can't always predict how they will display.
