Email marketing is a central tool for businesses to engage with their audiences. This paper explores the influence of academic language in email marketing, specifically focusing on consumer trust and decision-making processes. We compare academic language with conventional marketing language in terms of their effectiveness in building trust, authority, and customer loyalty. The study investigates whether using a formal, scholarly tone in emails leads to better customer responses, especially in sectors that demand a higher level of expertise and professionalism. With the rapid growth of digital marketing, businesses have increasingly turned to email marketing as a way to engage with their audiences. However, the tone of voice used in these emails plays a crucial role in how consumers perceive the brand and how likely they are to engage with the content. Academic language, often associated with credibility and professionalism, is one possible approach to constructing an email message. This paper aims to investigate the impact of academic language on consumer trust and decision-making.
