# MK-411 | Newsletter Subject Line Draft

For ordinary chat, upload `packs/mk-411.md`, which includes the shared rules, this method, and required references

## Purpose

This skill delivers: **Non-misleading subject lines that match the content**

Do not send messages or create automation without approval; if a tool cannot show recipient eligibility, do not assume everyone can be messaged

## Required inputs

Provide: friend or subscriber status, permissions, product content, campaigns, and channel reports

## Method steps

1. Newsletter subject lines should make the email's content understandable while giving recipients a reason to open it
2. Promotional subjects may use urgency, convenience, or curiosity, but must match the actual campaign conditions
3. Show the full brand name in the sender field to increase trust
4. The course materials also suggest a concise mobile layout: use approximately 16 Chinese characters as an initial subject-line design basis; full display still depends on the device and email interface

## Calculation and interpretation

Verify contact consent, unsubscribes, and message specifications; friend counts and open rates are not sales
