The California-based agency has acquired two interactive marketing agencies in New York to give it a presence on the East Coast.
These agencies, Conversa Marketing and Magnetik, are to be combined with StrongMail’s existing strategic services team and rebranded as ThreadMarketing, a StrongMail Company.
It will specialise in email and social customer relationship management. Services ThreadMarketing will offer include persona development and social media monitoring as well as running email and social media campaigns.
ThreadMarketing is headed by Michael Della Penna, who was previously CEO of Conversa Marketing. He said: "When looking at how the online marketing world has evolved over the past two years, having a single view of the customer has never been more important."
Clients of Conversa and Magnetik include Castrol and People.com.
