Adestra has released its latest email subject line analysis report, looking at the keywords and phrases that fare best and worst across a number of sectors. With email volumes on the rise and clutter an issue for recipients, having a strong subject line is as important as ever, particularly as consumers rate the subject line as one of their top motivators for opening an email. This article contains a summary of highlights from the Adestra report, which is based on a random sample of more than 90,000 email campaigns, each with a minimum list size of 5,000, totaling more than 2 billion emails.
Adestra’s study scores keywords by relative open, click, click-to-open, and unsubscribe rate. As such a result of 20% should be read as “20% higher than the average.” (In other words, if the average were 20%, the open rate would be 24%.) This article focuses on open, click, and click-to-open rates only. Read the rest at MarketingCharts.
