Email marketing has evolved since its early beginnings in the 1970s when a Marketing Manager at Digital Equipment Corp sent a mass email to a few hundred recipients. Its novelty generated over $13 million worth of sales and heralded the birth of email marketing. Fast forward to today, 3.7 billion people use email and this will increase to 4.3 billion by 2022. This way, emails are great way for marketers to be in touch with their customers.
