The Direct marketing Association has published research which suggests that the sector could grow 7% this year to reach nearly £15.2bn.
Fuelling this growth is the burgeoning expenditure on digital channels as well as an 11.5% increase in email marketing investment to £2.5bn and an 8.1% boost to social marketing spend to £2.2bn.
Internet search advertising spend is expected to increase 6.3% to £516m over the same period.
The 600 UK companies polled were found to attribute 23% of their total sales to direct marketing with the travel & leisure, retail & wholesale and financial services sectors all registering above average spend.
Commenting on the findings Chris Combemale, executive director of the DMA, said: "While the UK remains mired in a protracted recession, the creative industries are among the few that are performing strongly, with direct marketing in particular making an outstanding contribution to the UK economy.
"The industry is bucking the prevailing trend with increases in overall expenditure and employment figures forecast for 2012.”
