Target Marketing profiled Jenny Craig's use of click to call last week for their TM Tipline newsletter.  According to the report, which features an interview with Jenny Craig's director of interactive marketing, Trish Arellano, "For marketers working to provide a seamless cross-channel customer service experience, click-to-call technology provides one more tool to help achieve company goals. The technology allows consumers to click a button embedded in a Web page or e-mail to connect with a company’s customer service representative. After the user clicks, customer service representatives either are reached using Voice Over Internet Protocol (VOIP) or users are prompted to type their phone number and request an immediate phone call. This enables marketers to service Web customers without forcing them to abandon their Web sessions. In addition, the technology allows marketers to monitor when users switch from Web sales channels to phone sales channels."
