Email reactivity rate refers to the percentage of recipients who actively engage with an email by opening, clicking, or responding to it. This metric is used to measure the effectiveness of an email campaign and can provide valuable insights into the engagement level of a target audience. A high email reactivity rate indicates that the email content is resonating with the recipients and driving desired actions, while a low rate may suggest that the email needs to be optimized for better results. In today’s digital age, where email marketing is a crucial tool for businesses, understanding and improving email reactivity rate is essential for achieving successful communication and conversions.
