Design, Then Inline.
Make your html work in emails.
Email services like Gmail and Hotmail don't like stylesheets. The only way around it is to use inline styles. Replacing stylesheet references with inline styles is painful. Use Tamtam to do the dirty work for you.
How it works
Creating HTML emails that render consistently across email clients is frustrateds by programs like Gmail that strip out CSS styles from the head, and only support inline styles.
For most people it's prohibitively cumbersome and time consuming to modify html with inline style, and it's way easier to change the design first then apply inline styles at the end.
Mad Mimi's Tamtam widget accepts a URL, and then automatically generates and applies inline styles from the CSS in the head of that page. Tamtam works with most CSS cascades, even complex ones, and in most cases it saves you a ton of time. So just build the page in your normal way, then have all the inline style drudgery done for you by Tamtam.
