Most marketers will up their spend on email marketing this year, as digital advertising budgets experience yet another increase.

That's according to new research from BtoB Magazine, whose outlook for 2013 should read positively for marketers lending their expertise to a wide range of channels.

Conducted in November 2012, the study indicated that slightly fewer than half of US marketers have set their sights on increasing overall marketing budgets this year. Meanwhile says an even larger figure of 67.2 per cent will allocate more spend towards advertising products and services on digital platforms.
