To measure the relevance of your emails, monitor key performance indicators (KPIs) such as:
Open Rates: A high open rate indicates that your subject line and preheader text are relevant and compelling. Click-Through Rates: A high click-through rate suggests that the content within your email is engaging and relevant to the recipient. Conversion Rates: This measures how many recipients took the desired action, such as making a purchase or signing up for a webinar, indicating the ultimate relevance of your email content. Unsubscribe Rates: A low unsubscribe rate is a sign that your emails are relevant and well-received by your audience.
