San Bruno, Calif.—Email marketing volume remained at record-setting levels during the month of June, with volume growth for the year expected to exceed 2011's level, according to a study by email marketing company Responsys Inc.
Individual email campaigns averaged 15.8 promotional emails during June, an increase of nearly 21% year-over-year.
According to Responsys, email volume will grow about 20% this year, compared with 16% growth last year. This is due to a shift away from such traditional channels as direct mail and print; enhanced email ROI versus other channels; and recipients' preference to receive commercial messages via email, according to Responsys.
