All types of businesses use email as a way to establish ongoing dialogue with customers and prospects. But crafting effective email marketing campaigns requires a successful blend of art and science.
Through an analysis of more than 260 million emails delivered across 540 campaigns, Retention Science, a retention marketing solution provider, discovered that email subject lines that are between six and 10 words perform the best with a 21% open rate. Contrary to this finding, the majority (52%) of emails today have 11- to 15-word subject lines, and in turn, only garner a 14% open rate. Campaigns studied by Retention Science involved retailers in specialty goods, apparel, baby products, flash sales, whose and nutritional supplements, among others.
