I’ve typed about how important your Subject: field is in regard to how you are perceived, your level of professionalism and tech savvy and how your Subject: field structure and content can contribute to even if your e-mail is opened.
Today I read an article about the how Email Analytics Reveal Sweet Spots In Subject-Line Length. These sweet spots are 50 characters or 80 — with 60-70 characters not being as effective. Go figure! Just goes to show how we are all trying to balance and determine the fine line of what works and what doesn’t with business e-mails.
Give the full article a read and then remember, Subject: fields matter even more than we know and that trying new things, switching around words, offers, or number of characters can actually help or hinder your results!

Judith, thanks for pointing out the article, but I’m not convinced that Quist’s theory is accurate. I have tested different lengths of subject lines over the past ten years and find that it depends on the quality of the content, not the number of characters used
