Read time analytics show how long recipients spend reading your internal emails sent through Outlook. This feature tracks whether emails were glanced at, skimmed, or fully read.
Important: Read time is only available for Outlook users. This feature is not available to Gmail customers due to technical limitations with Google's email platform.
What Read Time Measures
Read time data categorizes recipient engagement into three levels:
| Engagement Level | Time Spent | What It Means |
| Glanced | 1-3 seconds | Recipient briefly opened the email |
| Skimmed | 3-9 seconds | Recipient quickly reviewed the content |
| Read | 9+ seconds | Recipient spent time engaging with the email |
Note: Read times are aggregate totals, not unique per recipient or device.
How Read Time Tracking Works
When a recipient opens your tracked email, a tracking pixel loads and continuously refreshes at regular intervals (every 3 seconds) to measure duration. When the recipient moves to a different email, closes Outlook, navigates elsewhere, or otherwise leaves the email, the read time stops and is categorized into one of the three engagement levels.
Read time tracking only works on these email clients:
- Classic Outlook
- Outlook for Mac
- Outlook on iOS
Where Read Time Does NOT Work
Read time tracking will not function if:
- The email is opened in Gmail or Apple Mail
- The email is opened in New Outlook or Outlook on the Web (OWA)
- The recipient has enabled the Outlook image proxy service (this prevents the continuous pixel refresh needed for accurate tracking)
Tracking Process:
- When a recipient opens your email in a supported client, the timer starts
- When they navigate to a different email or close the message, the timer stops
- The total time is categorized into glanced, skimmed, or read

Using Read Time to Improve Engagement
Read time analytics help you:
- Identify effective content: Compare read times across different email types to see what resonates with your audience.
- Optimize send timing: Use read time alongside the engagement distribution timeline to identify when employees have time to fully read emails, not just open them.
- Measure content value: Track whether recipients are engaging deeply with your newsletters or just scanning them.
- Refine your strategy: Test different content formats, lengths, and structures to increase read time percentages.
