There are multiple reasons for quality loss in email marketing:
Poor Content: Unengaging or irrelevant content can result in low engagement rates. Bad Design: Emails that are not optimized for different devices can lead to a poor user experience. Ineffective Segmentation: Sending generic emails to a diverse audience can reduce relevance and engagement. Spam Filters: Emails marked as spam can significantly reduce deliverability. List Quality: A poor-quality email list with outdated or incorrect addresses can lead to high bounce rates.
