Identifying diminished returns involves tracking key metrics over time to spot patterns of decreased effectiveness. Key performance indicators (KPIs) to monitor include:
- Open Rates: A declining open rate may indicate audience fatigue or ineffective subject lines. - Click-Through Rates (CTR): A decreasing CTR could suggest that your content is no longer engaging or relevant. - Conversion Rates: Lower conversion rates may highlight issues with your call-to-action or landing page. - Unsubscribe Rates: A rising unsubscribe rate can signal that your email frequency or content is off-putting to subscribers.
