The Size of the Hosted Email Marketing Industry

Estimates of the size of the email marketing industry vary widely. Forrester Research estimated 2009 email marketing vendor revenue to be $1.2 billion.  This estimate may be conservative. Based on US Census numbers and a review of more than 50 email marketing vendors, Marketing Growth Strategies, LLC, estimates a total market size of $1.5 billion for 2010 and an annual growth rate of 20% to reach $2.6 billion in 3 years . The table below shows the numbers of businesses by employee size and our estimate of the penetration of hosted email marketing vendors for each category.

Although email marketing may seem fairly ubiquitous today, the industry as a whole is in its early stages. Penetration among large firms (with 500 or more employees) is estimated at 75%, but very small firms (those with less than 20 employees) have barely begun to explore email marketing.

In his book, Crossing the Chasm, Geoffrey A. Moore describes a technology lifecycle in which the adoption or acceptance of a new product or innovation proceeds according to the demographic and psychological characteristics of defined adopter groups. The model indicates that the first group of people to use a new product is called "innovators," followed by "early adopters." Next come the early and late majority, and the last group to eventually adopt a product are called "laggards". If this model is applied to the hosted email marketing sector, it becomes obvious that the industry has a much room for growth. The figure below shows that email marketing among small and mid-sized businesses has only reached the ‘early adopters’ stage. This explains the large and growing number of email marketing vendors seeking to gain a foothold into this expanding market.
