I covered The Anatomy of a Perfect Email last month, so now is a good time for a quick follow-up:

Campaign Monitor, the best damn email marketing company out there, released a set of Email Design Guidelines, a technical guide that everyone should keep handy. Even more technical is their Guide to CSS Support in Email, which takes some of the guesswork out of what styling you should and shouldn’t use in your emails.

Over at ONE/Northwest, former Moveon.org Advocacy Director Ben Brandzel goes over Four Rules for Effective Email Alerts. Covering both structure and content, it’s a good, quick read from someone who pioneered email advocacy.

Last but not least, Colin Delaney over at e.politics has just put out a new version of his Online Politics 101 Ebook. The whole thing is great, and there are quite a few pages devoted to email strategy.
