There are several factors that can contribute to list fatigue:
Frequency of Emails: Sending emails too frequently can overwhelm subscribers, while sending too few can make them lose interest. Irrelevant Content: If the content of the emails does not match the interests or needs of the subscribers, they are likely to disengage. Poor Email Design: Emails that are difficult to read, unattractive, or not mobile-friendly can lead to subscriber fatigue. Inconsistent Sending Schedule: Irregular sending schedules can confuse subscribers and lead to disengagement.
