How to read the numbers

Rates (%) vs absolute numbers

This report shows both rates — open rate and CTOR — and absolute numbers — sends, opens, clicks. With different send volumes the percentage can move differently from the absolute counts, so we always show them side by side (year-over-year change: volume +30 %, opens +45 %, clicks +167 %).

Rule of thumb: read reach from absolute opens/clicks, and targeting quality from the rates.

Where to focus

Keep repeating what worked and lift the weaker metric — where opens are strong, push clicks (CTOR); where clicks lead, sharpen the subject and open rate.

Best and weakest campaigns 2026

Top campaigns of the month — OR & CTOR

For each month, the top 4 by OR (%) · opens (absolute) · CTOR (%) · clicks (absolute). Switch best / weakest. Only sends above 20,000.
Great work! 🎉 Definitely repeat the top performers. Where open rate (OR) won, next time focus more on clicks (CTOR) — and where clicks led, work on the subject and open rate. For the weaker campaigns, look for ways to lift performance next period (different subject, preheader, timing or offer).
Experimentation & learnings

A/B tests & Verified hypotheses

For each test we show the winning variant and its uplift — the + % shows how much higher OR (subject tests) or CTOR (content tests) the winner had than the other variant. Below are the hypotheses confirmed through testing.
