An editing exercise, not a universal reading-time rule or accessibility test.

Audience and why this message is expected:

Important detail needed to decide:
Main action and destination:
Reviewer and date:

Show the draft for roughly 12 seconds, then put it away.
Ask without prompting:
1. Who was it from and who was it for?
2. What was useful or important?
3. What would you do next?

Record the actual answer, what was missed and one change to make.
Allow a separate untimed review for accessibility and full comprehension.
Repeat using the updated draft; this is formative feedback, not a conversion forecast.

Before sending: preview mobile/desktop, check images-off meaning, links, offer details, reply address and opt-out.
After sending: record relevant clicks, enquiries, replies or completed actions using consistent definitions. Opens alone do not establish understanding or intent.
