The results are in for over 9m emails across 6 industry sectors. In our August webinar, Account Director Parry Malm provided an in-depth review of our latest subject line report and covered best practice advice for subject line lengths, word limits and popular phrases that can yield high engagement rates from your emails.
Below are the key points he felt we should take away:
Subject lines are your movie trailer. First and foremost your subject lines should clearly describe the offering in your email and the benefit to the reader. Does length matter? The report suggests it does and longer subject lines surprised by demonstrating higher click to open rates compared to shorter ones. Furthermore, long sentences should be used for promoting multiple benefits in order to entice the recipient to open your email. Word count analysis showed that short and long subject lines worked best but somewhere in the middle of that trend, the engagement rates were diminished.
Choosing the right words to include in your subject lines is equally important. The research showed that phrases such as “Free” and “Sale” were popular for the ecommerce industry. The publishing industry however benefitted from subject lines which promoted exclusive content in an email such as video or top stories. Testing is important factor in determining the best subject line formula for your email campaigns.
