32.4% relative increase in engagement from re-engagement subject line personalization
Batch-and-blast overwhelm to targeted, automated personalization
The case study earns credibility by anchoring each tactic to a specific result number, making the connection between mechanism and outcome clear. The story moves logically from strategy to segmentation to content to loyalty, so readers can follow the progression. The small-team angle adds an accessible hook that makes the results feel replicable rather than resource-dependent.
Pair each personalization tactic with its own discrete result metric rather than rolling all wins into a single summary number. This lets readers evaluate each tactic on its own merits.
