Study: Shorter E-mail Subject Lines Perform Better

Here are some guidelines for successful e-mail subject lines culled from the Epsilon report:

1. Front load subject lines with the most important information.
2. Keep the subject line as short as possible to convey the message.
3. Use longer subject lines only when there is a compelling reason to do so.
4. When in doubt, test.
