Vague Language: Using generic phrases like "Click Here" or "Learn More" without context can leave readers unsure of what will happen when they click. Multiple CTAs: Including too many CTAs in a single email can overwhelm readers and dilute the focus of the message. Poor Design: If the CTA button is not visually distinct from the rest of the email content, it can easily be overlooked. Lack of Urgency: Without a sense of urgency or a clear value proposition, readers may not feel compelled to act immediately.
