Introduction
Email marketing is one of the simplest yet most powerful ways for businesses to reach customers instantly. In a digital world where attention spans are short and competition is fierce, the ability to deliver a message directly into a customer’s inbox within seconds is invaluable. Unlike social media posts that depend on algorithms or paid ads that require constant spending, email marketing gives businesses control over their communication.
