eMarketer estimates that last year, the majority of US adults used digital coupons, and that figure will rise to 55.0% this year. Judging by recent research, it’s likely that many of those coupons will come from emails.
According to a Q4 2013 study, emails sent by Experian Marketing Services clients that included coupons saw more success than those with no coupons.
