When evaluating the performance of newsletters, we analyse such indicators for understanding their impact and effectiveness. Here's a list of statistics that we provide for newsletter performance

Open Rate

The percentage of recipients who opened the newsletter. This metric is crucial for gauging initial engagement.

Click-Through Rate (CTR)

The percentage of readers who clicked on one or more links contained in the newsletter. This indicates how effective the newsletter is at encouraging readers to take action.

Conversion Rate

The percentage of readers who took a desired action (like making a purchase or signing up for an event) after clicking a link in the newsletter.

Bounce Rate

The percentage of emails that could not be delivered to the recipient's inbox. This includes both hard bounces (permanent issues like invalid email addresses) and soft bounces (temporary issues like a full inbox).

List Growth Rate

The rate at which your email list is growing, taking into account new subscriptions and unsubscribes.

Unsubscribe Rate

The percentage of recipients who opt-out of your mailing list after receiving the newsletter.

Engagement Over Time

Tracking how engagement with your newsletter changes over time (daily, weekly, monthly).
