3Seventy, a provider of mobile engagement solutions, has announced the launch of a new SMS marketing campaign for Harman Management, the owner of A&W Burger franchises with almost 200 locations on the West Coast.

For the initial campaign, 3Seventy teamed up with AFA Krause Advertising and Harman Management.

The franchisees wanted to drive more traffic to specific locations with mobile and developed an offer for one free Papa Burger for customers who texted the keyword BURGER to short code 70626. The response exceeded initial expectation, with more than 36,700 opt-ins during the first month.

“We know SMS coupons are a highly effective way to drive customer response, but are overwhelmed by the success of this mobile campaign,” said Amber Hampshire, account supervisor at AFA Krause Advertising.
