# MK-401 | Three-Part LINE Welcome Message

For ordinary chat, upload `packs/mk-401.md`, which includes the shared rules, this method, and required references

## Purpose

This skill delivers: **An immediate benefit, a next step, and a clear action**

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. The welcome message is the first sales script after adding the account, rather than a greeting alone
2. Three parts: first sentence, immediate benefit; second sentence, next-step guidance / expectation-setting; third sentence, a clear CTA
3. Depending on the industry, the CTA may lead to a coupon, quiz, product recommendation, appointment, diagnostic form, or content; no single destination is mandatory

## Calculation and interpretation

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