List size is a vanity number. Revenue per subscriber is the one that pays for the programme, and it moves when the message matches what someone has actually done in your product or store.
What the engagement covers
- Onboarding and activation flows built around usage triggers.
- Win-back and churn-risk sequences with real exit criteria.
- Segmentation that a marketer can maintain without an engineer.
- Deliverability work: authentication, warming and list hygiene.
- CRM handoff so sales sees the same behaviour you do.
