How this tool works

No black box. This is the exact logic the tool runs on every input you give it.

Formula Open Rate = (Unique Opens ÷ Delivered) × 100 • Delivered = Sent − Bounced

    Apply the formula above with full precision, rounding only at display time.

  3. 3

    Derive the secondary metrics that put the headline number in context.

  4. 4

    Benchmark the result against the typical range for this metric, so you know whether it is good.
