Email is one of the most effective ways for businesses to advertise their services. While many businesses still use direct mail, their budgets might be better spent on email marketing. According to a partnership study conducted by the Data and Marketing Association and United States Postal Service, more than half (57 percent) of mail being sent at the time of the study was still direct mail.
But this strategy, the researchers said, produced a return on investment of just 7 percent. In comparison, email marketing offered an ROI of 28.5 percent.
