The biggest day of the year in 2006 for US retail e-mail marketers was the day after Christmas, according to E-Mail Experience Council data cited in Marketing Charts. More than 53% of retailers tracked in the study sent e-mail on December 26.
The day is favored for capturing added sales from returns as well as gift card and e-gift card sales as quickly as possible.
Other popular days with e-mail marketers included Cyber Monday (the Monday after Thanksgiving) and days related to holidays they preceded, such as Mother's Day, Father's Day, President's Day, Valentine's Day, Easter and Tax Day.
E-mails were sent on Tax Day (April 17 in 2006) to get sales from tax refunds.
None of the 20 most popular e-mail days fell in July, August, September or October.
