Measuring credibility can be challenging, but there are several key metrics that can provide insights:
Open Rates: A consistently high open rate indicates that subscribers trust you and find your emails valuable. Click-Through Rates: High click-through rates suggest that your content resonates with your audience. Unsubscribe Rates: Low unsubscribe rates indicate that your audience remains interested in your emails. Spam Complaints: A low number of spam complaints is a good sign of credibility.
