Under the deal, eGain will manage FreeOnline's high volume of email traffic.
The alliance will allow FreeOnline to route, track and respond to large volumes of customer email and Web form submissions, enabling customer response in realtime.
"FreeOnline receives hundreds of e-mails each day and our success in acquiring new members has given rise to a need to seek an integrated solution to providing rapid response times for customer emails," said FreeOnline's chief executive officer Sydney Low. "And as we grow, so does our need for an effective communications solution."
