Information overload can be detrimental for several reasons: - Reduced Engagement: When emails are too dense, recipients may lose interest and stop reading. - High Unsubscribe Rates: Overwhelmed readers are more likely to unsubscribe from your list. - Poor Brand Perception: Consistently overwhelming emails can create a negative impression of your brand. - Lower Conversion Rates: If recipients can't find the key message, they're less likely to take the desired action.
