There are several ways to measure immediate responses:
Open Rates: This metric shows how many recipients open your email. High open rates indicate that your subject line is effective. Click-Through Rates (CTR): This measures the percentage of recipients who clicked on a link within the email. A high CTR suggests that the content and CTA are engaging. Conversion Rates: This measures the number of recipients who took a desired action, such as making a purchase or filling out a form. High conversion rates indicate a successful campaign.
