Jupiter Research issued a press release with some high level forecasts on the growth of Email marketing. They predict email marketing spending will grow from $1.2 billion in 2007 to $2.1 billion.
Interestingly, a point they highlight which is obvious to us is that spending on retention will outpace spending on acquistion. David Daniels, Jupiter vice president and research director , emphasizes “... marketers will have to work harder to remain relevant in their communications with their intended audiences.”
It seems to us that the growth is coming from getting smarter about email.
