American Express has introduced a mobile offers engine that recommends and ranks real-time merchant offers for U.S. cardholders based on the spending history and location, or “spend graph.” The new “My Offers” service is being piloted in American Express’ iPhone app, and builds on its card sync programs with Facebook, Foursquare and Twitter.

Recommended local offers will initially be concentrated in Los Angeles and New York City, but with some available nationwide through chains such as Baskin-Robbins and Dunkin’ Donuts. Through the iPhone app, users will be able to see a list of relevant offers which they can sort, based on location or expiration date.

The My Offers dashboard allows people to see what offers have been added to their card, how much was saved, and which have ended.

To redeem an offer, users just add it to their American Express card and use the card to complete the qualified purchase online or in-store. The savings are automatically loaded and delivered in a statement three to five days later. The discounts that customers receive include those coming from its Facebook, Foursquare and Twitter programs.

Josh Silverman, president of the U.S. consumer services group at American Express, said the new mobile service was designed to help customers get a better handle on the explosion of daily deals. “At the same time, we can help our merchant partners build their business by helping them reach the right cardmembers with the right offers at the right time,” he stated.

To help fuel the new service, American Express has also upgraded Go Social -- the tool it launched last year to help small businesses create social and mobile offers, target cardholder segments and receive detailed reporting on their offers.
