Statistics that fail independent corroboration are excluded.

Email Marketing Campaign reporting is tightening fast, and 2026 benchmarks show open rates slipping to 20.5% while click rates hold at 3.2%. That gap is where the real story lives, because the list can look engaged without driving much action. In the rest of the dataset, you will see which performance levers are narrowing that mismatch and which are quietly falling behind.
