Two out of three Internet users in the US has purchased products that they have been recommended through snail mail. Email is very popular too as a purchase recommendation tool.
That is one of the conclusions that arise from a recent study by eMarketer.
Among all the direct marketing channels email is the most accepted one among users only surpased by postal traditional mail. Un a 1 to 5 valoration scale, surveyed users give email 3.7 points. The rest of marketing channels, such as phone or instant messaging, get less than 3 points in teh survey.
News sent through social networks are not very effective. Just a mere 6% of the purchases were generated through this kind of communcation.
