Several factors can contribute to user fatigue in email marketing:
High Frequency of Emails: Sending too many emails in a short period can overwhelm subscribers. Irrelevant Content: Emails that do not meet the interests or needs of the subscriber can lead to disinterest. Poor Email Design: Emails that are hard to read or navigate can frustrate users. Lack of Personalization: Generic emails that do not address the subscriber's specific preferences or behavior can lead to disengagement.
