Starbucks Employee E-mail Incentive Backfires

Call it the case of unintended viral marketing that got way out of hand.

Starbucks had to abruptly rescind an e-mail promotion earlier this week for a free iced coffee for employees, their friends and family because too many people were trying to redeem the coupon.

The company sent the offer for a free cup of iced coffee to employees in the Southeast on Aug. 23 instructing them to forward it to their friends and family.

The e-mail apparently went viral, and quickly spread throughout the Internet.

“Unfortunately, it [the coupon] has been redistributed beyond the original intent and modified beyond Starbucks’ control,” the company said in a statement. “Effective immediately, this offer will no longer be valid at any Starbucks location.”

A company spokesman declined to quantify how out of control the promotion became before Starbucks pulled it.
