Email Marketing has been around for a long time and some question its effectiveness. Yet, I am here today to let you know that email marketing for Information Technology and Software Companies has, on average, a 4,4% return on investment (ROI), making it a highly effective way to generate and close more leads. 92% of U.S. adults use email, and 70% on average have used a coupon or discount from a marketing email in the past seven days. It is one of the most cost-effective forms of advertising there is.
