Why this matters in 2026

Write one sentence for the business outcome behind 2026 Email-SMS retention Practical Workbook for Startups. List constraints (strict compliance constraints). Reject work that does not serve the sentence.

2) Ownership map

Assign planning, production, QA, and measurement owners. Publish the map where the team already works.

3) Control stack

• variant/title consistency checks (delivery gate)
• speed budget for theme scripts (review gate)

4) Delivery rhythm

Ship in small increments. After each release, add links to the Shopify hub and sibling cluster pages.

5) Learning loop

Compare planned vs actual every week. Keep, fix, or stop. Do not expand while promo code attribution hygiene is failing.
