Consumers confuse logistics delays with clinical outcomes when wording blurs the two. Messaging stacks should borrow airline-grade clarity — status versus implication.
Separate logistics from clinical readiness
Separate operational notices (‘phlebotomist delayed’) from clinical readiness (‘report uploaded’) across templates. Never imply interpretation via push character limits.
Tone without diagnosis
Localise respectful greetings without implying diagnostic conclusions pending physician review. QA/legal paired review beats marketing solo drafts.
Preference centres earn trust
Instrument preference centres early — suppression mistakes erode trust faster than over-notification. Default transactional channels separately from education drip campaigns.
