ETForms is a brand new form building tool, designed from scratch to integrate seamlessly with ExactTarget. ETForms incorporates marketing user feedback and addresses limitations and frustrations of working with other form builders and existing landing pages in ExactTarget. It is easier, faster and more powerful and can be used to replace the existing form builder.
Adinfinity is an early ExactTarget development partner, and has built ETForms as a native ExactTarget HubExcahnge App. It will be officially released and available in the ExactTarget's Hub Exchange in mid September 2013.
