First of all, let me say that I love Alyson B. Stanfield's ArtBiz Newsletter and Blog. I began as a "lazy looker," but I'm determined this year to take action and "Do This..." Anyway, Alyson just finished her book, I'd rather be in the studio! The Artist's No-Excuse Guide to Self-Promotion. Alyson is marketing her book in the most creative way--a Blog Book Tour!
Claudine Hellmuth's blog was a recent Blog Tour Stop. Go there (I love Claudine's blog too!) and check out their discussion on E-newsletters.
I must confess, I haven't read Alyson's book yet, but her advice is always right on target. So, no excuse--I'm going to get her book!
