What This Calculator Measures

Plan email freeze windows using inbox volume, response targets, and focus blocks.

By combining practical inputs into a structured model, this calculator helps you move from vague estimation to clear planning actions you can execute consistently.

This calculator estimates email freeze coverage and batching needs.

How to Use This Well

  1. Enter daily email volume and minutes.
  2. Set freeze hours and response goal.

Formula Breakdown

Email time = emails x minutes
Coverage: freeze hours / work hours.
Batch: email time / windows.
Focus: focus / email time.

Worked Example

  • 65 emails at 1.5 min = 97.5 min.
  • 3 freeze hours gives 37.5% coverage.
