Standalone email application service provider Responsys re-emerged as a leader after overhauling its platform and corporate strategy, according to a report by Forrester Research, which single out the company for top honors in email marketing, writes DM News. Responsys is better as an application service provider than as a full-service solution, Forrester said, "so marketers seeking an e-mail agency should look elsewhere."

Forrester said Responsys's interface, dynamic content, reporting and integration capabilities are particularly strong, making it a good choice for enterprise or mid-market users.
