Definition
Attention rate measures the percentage of email opens where the recipient spent meaningful time reading the content. Unlike open rate — which can be inflated by Apple Mail Privacy Protection auto-loading tracking pixels — attention rate filters out passive opens and gives a truer picture of genuine engagement.
A high attention rate indicates your content resonates enough that subscribers stop and read. A low attention rate with a high open rate typically means your subject lines are effective but your content does not deliver on the promise.
Formula
Attention rate is calculated by dividing the number of opens that lasted longer than a threshold (usually 5 seconds) by total unique opens.
Attention Rate = (Opens Longer Than 5 Seconds / Total Unique Opens) × 100
Why It Matters
Open rate has become less reliable as privacy features like Apple MPP automatically load tracking pixels. Attention rate removes this noise by measuring actual reading behaviour. It is a stronger predictor of future engagement and conversion than open rate alone.
