Why this matters
The reader needs to turn this newsletter guidance into a usable campaign decision, not only understand the definition. The practical job is to clarify audience, message hierarchy, CTA, production constraints, and the review standard before creating or updating the template.
How to decide
- The answer maps to the real newsletter campaign goal and audience.
- The recommendation keeps one primary action clear.
- The resulting template can be reviewed on mobile before sending.
- Best preheaders complete the promise of the subject line and avoid repeating it verbatim.
Before you build

What good looks like
- The reader can explain the decision and apply it to a real campaign.
- The template has one clear message path and one primary next action.
- The output can move into generation, editing, or ESP QA without a new strategy pass.
- The final draft avoids the common mistake: Repeating the subject line exactly.
