How are engagement metrics defined?

In Email Analytics, Litmus shows you how long your subscribers were engaged with your message. This is sometimes also known as the read rate. Since we're measuring how long the recipient had the email open, we report this back in three categories: Read, Skim Read, and Glanced.

Read: 8 or more seconds

Skimmed: 2 or more seconds, but less than 8 seconds

Glanced: less than 2 seconds

Please note: Exported reports of engagement data may show a result of '-1' as the engagement rate. This means that engagement rate tracking in this email client is not supported. You can read more about this under the Webmail Engagement Tracking section of our help document.
