Marriott International Inc. and Hilton Worldwide are among the growing list of companies affected by a data breach last week that provided unauthorized access to customer names and e-mail addresses.

The affected files didn’t include customer financial information or physical addresses, the hotel chains said in separate statements today. The breach occurred at Epsilon, a Dallas-based provider of e-mail marketing services.
