A few reasons contribute to diminishing returns in email marketing:
Email Fatigue: Subscribers can get tired of receiving too many emails, leading to lower engagement. Relevance: If the content is not highly targeted and relevant, additional emails won’t provide much value. List Quality: A poorly maintained email list can result in diminishing returns. It’s essential to regularly clean your list to ensure it contains engaged subscribers. Over-Saturation: Competing with numerous other emails in a subscriber's inbox can reduce the effectiveness of your email campaigns.
