In Forrester's evaluation of through-channel marketing automation (TCMA) platforms, we identified 14 significant vendors — Averetek, Balihoo, BrandMaker, Brandmuscle, Bridgeline Digital, Distribion, EarthIntegrate, Partnermarketing.com, Revenew, SproutLoud, Standard Register, StructuredWeb, TIE Kinetix, and Zift Solutions — and researched, analyzed, and scored their products according to 20 criteria garnered from our interactions with B2B marketing professionals. This report details our findings about how well each vendor's product meets those criteria — and where they stand in relation to each other — to help B2B marketing professionals identify the top vendor candidates for their through-channel marketing programs.
