A June 2016 survey of US marketers conducted by the Direct Marketing Association (DMA) and Demand Metric found that email had a median ROI of 122%—more than four times higher than other marketing formats examined, including social media, direct mail and paid search. Agency professionals and in-house marketers worldwide are in agreement about email’s effectiveness, according to March 2016 polling from Econsultancy. Both groups named email marketing most frequently as a tactic able to provide a strong ROI, at 80% and 73%, respectively. The study also found that while respondents allocated an average of 16% of their overall marketing budget to email for 2016, the program contributed to 23% of total sales, a ratio that indicates email’s positive ROI. Revenue from email has also improved year over year. A survey from the Relevancy Group sponsored by PostUp found that in December 2015, 24% of US email marketers said email marketing initiatives accounted for over a quarter of their overall revenues. This percentage was up from 13% in fall 2013. Get the full story at eMarketer
