To evaluate the effectiveness of your email newsletters, track key metrics such as open rates, click-through rates, and conversion rates. Open rates indicate how many recipients are opening your emails, while click-through rates show how many are engaging with your content.
Conversion rates measure the number of recipients who take a desired action, such as making a purchase or signing up for an event. Use these metrics to assess what is working and what needs improvement. A/B testing different subject lines, content formats, and send times can also help optimize your newsletters.
