In the Newsletter report dashboard, engagement statistics are displayed about the performance of the Newsletter. Here is a guide to better understanding what each statistic represents:
Sent at: Date and time the newsletter was sent.
Edition ID: For users running multiple editions, this denotes the edition of the newsletter.
Issue #: Numerical ordering of the newsletter (Edition-specific).
Open rate (%): Total opens divided by total delivered messages.
Click rate (%): Total clicks divided by total delivered messages.
CTR %: Total clicks divided by total opens.
Unique open rate (%): How many different individuals have opened the newsletter, divided by total delivered messages.
Unique click rate (%): The number of different individuals that have clicked the links in your newsletter, divided by total delivered messages.
Delivered: Number of emails that successfully reached the inbox.
Total opens: How many total times the newsletter has been opened.
Unique opens: How many different individuals have opened the newsletter.
Total clicks: How many total times the newsletter has been clicked.
Unique clicks: the number of unique individuals that have clicked the links in your emails.
Deferred: A deferred status can occur when an ISP or mailbox provider is for some reason not ready to accept email from your IP address. Instead of blocking or bouncing the message, the provider will defer or temporarily delay receiving the message and wait for the email to be resent. Threadloom retries delivery for 72 hours so a single email may generate multiple deferrals before it is delivered or suppressed.
Unsubscribe: Number of users who unsubscribed from the newsletter this issue.
Bounce: An email that the recipient server returns.
Spam report: Users who marked the newsletter as SPAM with their provider.
