We know, email is old tech (no surprise there) but it still plays a significant role in any marketing strategy. Here's why: an email campaign is still one of the most effective ways to promote your business, engage with both your customers and prospects, as well as reach your business goals. In fact, email is so good it's the third most influential source of information for B2B audiences, trailing only colleague recommendations and industry-specific thought leaders. In addition, it also delivers the best marketing ROI. Not too shabby for the "old dog".
