According to the study Market e-mail tracker 2018, e-mail marketing is considered the tool able to record the highest ROI, with a return on investment of € 33 for each euro spent. This type of direct marketing, being potentially suitable for all companies, is widespread. Today it is estimated that about 281 billion e-mails are exchanged, and it is estimated to reach 333 billion in 2022. Another significant data was obtained from a further study published by Market Research Reports Search Engine, which estimated the value of the global e-mail marketing market at around 19 billion euros. The study has also focused its attention on the particular use of e-mail marketing to increase the company’s strategies. The e-mail therefore continues to be the most reliable channel, able to generate the highest profitability.
