How Campaign Stats Are Calculated

Understanding your campaign metrics helps you benchmark performance accurately.

Open Rate

Definition: Percentage of delivered emails where the recipient opened the email.

Formula: (Unique Opens ÷ Delivered Emails) × 100

Benchmark: 40%+ is elite. 20–40% is good.

Note: Open tracking uses a 1-pixel tracking image. Apple Mail Privacy Protection (MPP) inflates open rates for Apple Mail users — treat open rate as directional, not exact.

Reply Rate

Definition: Percentage of sent emails that received any reply (positive, negative, or neutral).

Formula: (Replies ÷ Sent Emails) × 100

Benchmark: 5%+ is elite. 3–5% is strong. Under 2% needs attention.

Reply rate is the most important metric in cold email — it measures real human engagement, not pixel fires.

Bounce Rate

Definition: Percentage of sent emails that were undeliverable.

Formula: (Bounces ÷ Sent Emails) × 100

Threshold: We maintain under 3%. Above 5% risks domain reputation damage.

High bounce rate usually means list quality issues. Piqely uses Millionverifier to keep bounces low.
