Using 'Top 10' lists in Email subject lines

Excerpted from ConvUrgency.com's Smart Email Marketing Guide

E.g. "The Top 10 Subject Lines of This Year"

For some strange reason, people are fascinated with ‘top 10’ (or any other number) lists. You have simply to watch the Digg homepage to see how popular they are. I can’t explain why, perhaps people just like to validate whether or not the list matches their opinions, and debate it if not. Regardless of the rationale, they work, so use them in your subject lines.

So be creative, but use good, informative content. If you run a gardening website, try a ‘Top 10 Spring gardening tips”. Or if you’re targeting a specific job title, try something like: “Top 3 questions keeping [job title] up at night”, and of course the content explains how your product solves/answers their questions.
