Direct marketing agency Epsilon has released a new white paper on “creating subject lines that pack punch.”
Rethinking the Relationship Between Subject Line Length and Email Performance: A New Perspective on Subject Line Design offers important subject-line considerations for marketers, including these four tips:
1. Front-load subject lines with most important information.
2. Keep subject lines as short as possible.
4. Personalize the subject line, if possible.
You can also try subject lines that pique curiosity. For example, I’ve been using an email subject line to network with new-to-me professionals that seems to work rather well:
Group Hello and Question
It’s friendly and — I’m guessing — gets people to open it to find out what the question is.
