Spending in the US on email marketing is set to grow significantly over the next few years, according to a new study.
The study, put together by JupiterResearch, revealed that email marketing was expected to see growth from around $1.2 billion (£607 million) last year to an estimated $2.1 billion by 2012.
It was also noted that the quality of online marketing campaigns was set to improve as better technology to battle spam emails continues to be put in place.
The survey also revealed that spending for retention emails was expected to double by 2012 although it was noted that acquisition email marketing would see slightly slower growth.
Commenting on the results, president of JupiterResearch David Schatsky, said: "The email marketing landscape continues to evolve and marketers have to stay current with best practices to continue getting a good return on their investment."
