The Social Media Fusion tool allows clients to include links to a range of social communities such as Digg, Delicious, Facebook and Stumble Upon, which increase the exposure to marketing emails as recipients forward them onto to interested friends, family and business associates.
Volker Wiewer, chief executive of eCircle, said: "eC-messenger is a direct response to our clients needs and the software capitalises on the ever expanding mediums of targeted marketing and a greater demand for personalisation.
"This will result in the brands and businesses we work with producing more dynamic campaigns that can reach more receptive audience and ultimately improve the effectiveness of their email marketing programmes."
