NEW YORK (MainStreet) — Has your inbox been flooded with e-mails from every store you’ve ever shopped during the holidays this past week? If so, you’re not alone.

Nearly three quarters of all major retailers (74%)  sent out at least one promotional email to their subscribers on Thanksgiving Day this year alerting them to upcoming Black Friday and Cyber Monday deals, the highest percentage on record and a marked increase from previous years, according to data from Responsys, a digital marketing firm and email service provider. In 2010, 60% of retailers sent out promotional emails on Thanksgiving Day and less than half did the year before.

The percentage only increased on Black Friday this year when 81% of retailers were found to send out at least one email, which was presumably a last-minute reminder of promotions taking place that day and over the weekend. By comparison, just 69% of businesses emailed subscribers on Black Friday in 2010.

"With email volume up 19% year-over-year last week, retailers are making email central to their marketing efforts this holiday season,” says Chad White, Research Director for Responsys.

For better or worse, shoppers flooded with emails this weekend can expect to receive even more today as Responsys predicts that the number of emails sent on Cyber Monday will set a new record.

“After seeing record email volume on Thanksgiving Day and Black Friday, we expect promotional email volume to easily set a new all-time record on Cyber Monday, which has been the busiest email marketing day of the year for the past four consecutive years,” White says.

Responsys did not actually name any of the email-happy retailers, but chances are at least a few of them can be found on MainStreet’s roundup of the 11 stores that love to email their customers a little too often.
