Growing your startup is crucial, and connecting with customers through email marketing can be a highly effective way to do so. Email has remained the number one preferred communication channel amongst consumers since 1965 due to its numerous characteristics that make it ideal for customer engagement, such as being easily used on multiple devices, enabling genuine two-way communication, hosting longer content, and allowing the use of rich media. The ease and cost-effectiveness of email make it an attractive option for start-ups, with personalized interactions increasing customer engagement and revenue by 40% and up to 760% respectively. By segmenting audiences through data-driven insights, start-ups can tailor their emails, show they're speaking directly to the recipient's needs, and establish deep customer relationships that drive growth.
