CTR over time — every Saturday send
Each dot is one send. Vertical dashed line marks the Coffee with Kevin → Saturday with Sunrise rename, if both names exist in the data. CTR is the cleanest performance signal here — Apple's Mail Privacy Protection inflates open rates substantially since iOS 15, so we lean on clicks.
