There are several reasons why poor indexing can occur in email marketing:
Spam Filters: Modern email systems use sophisticated algorithms to filter out spam. If your email contains certain trigger words or phrases, it might get flagged. Poor List Management: Sending emails to outdated or irrelevant email lists can lead to high bounce rates and low engagement. Low-Quality Content: Content that is not engaging, informative, or relevant can lead to poor indexing. Technical Issues: Misconfigured email servers or issues with your email service provider can result in delivery problems. Lack of Personalization: Generic emails that do not address the recipient's needs or preferences are often ignored.
