Measuring Limit Phi can be a bit complex, but several key metrics can help you gauge when you might be hitting this threshold. These include:
- Open Rates: If open rates start to decline, it might indicate that your audience is becoming overwhelmed or uninterested. - Click-Through Rates (CTR): A drop in CTR can signal that your content is no longer resonating with your audience. - Unsubscribe Rates: A spike in unsubscribes is a clear sign that you are pushing the limits of your audience's tolerance. - Spam Complaints: An increase in spam complaints can indicate that your emails are becoming unwelcome.
