Analytics and Insights

Nid offers analysis tools to better understand your email habits and identify cleanup opportunities.


Activity Heatmap

A heatmap visualizes your email activity on a day of the week × hour of the day grid. Each cell indicates the number of emails received during that time slot.

Use this view to:

  • Identify your peak reception times (e.g., Monday morning, Tuesday 2 PM)
  • Understand when you receive the most emails

Clutter Scores

Each sender receives a clutter score calculated from:

  • Number of emails sent
  • Total email size
  • Number of unread emails
  • Read rate (read emails / total)
  • Presence of an unsubscribe link

The higher the score, the more the sender "clutters" your mailbox.

Dismiss a Suggestion

If a suggestion is not relevant, click Dismiss to hide it. It won't reappear.


Inbox Zero Tracker

The Inbox Zero tracker measures your progress toward an empty inbox:

  • Email count in the inbox
  • Unread email count
  • History: chart showing the trend over time

A snapshot is automatically recorded every 6 hours to feed the history.


Weekly Report

Every Monday, a weekly report is automatically generated for each Gmail account:

  • Number of emails received, archived, and deleted during the week
  • Top senders of the week
  • Rules executed and space freed
  • Comparison with the previous week

The report is sent as an in-app notification and can be viewed from the Insights page.
