Tips For E-Mail Newsletters
In the subject line of the message, you shouldn't have multiple characters in a row. This isn't a really bad one, but something to keep in mind. We've traditionally used two dashes in our subject line and that will change in our next newsletter.

- First, most email clients do not want to see or tags. In fact this can make your emails appear 'spammy' to the filter. The same goes for an extrenous tags, hence why WYSIWG editors - especially the MS ones - can be a problem.
- Additionally, CSS support and rendering varies wildly across ISP's and mail clients. The safest approach to take, if you do want to use CSS, is to only use inline CSS and only for styling attributes (color, font size, etc). All layout should be done in tables.
