Korean Ad Email Compliance Check — Network Act Article 50

Enter your sales email’s subject and body, and we’ll check whether the Korean ad-disclosure tag, opt-out instructions, and sender information meet Korean legal requirements. What you enter isn’t stored.

Why does this matter?

When sending commercial advertising emails in Korea, there are three requirements you must follow, under Article 50 of Korea’s Network Act. Violating them can result in a fine.

The Korean ad-disclosure tag at the very start of the subject line — recipients need to know it’s an ad before they even open it.

An opt-out method — the body must tell recipients how to stop receiving future emails. This matters beyond the law, too: without one, people report the email as spam instead, and enough spam reports get sending accounts blocked.

Sender information — you must state your company name, address, and contact information. Emails whose sender can’t be verified are more likely to get flagged as spam.

Sending times are restricted too — to send advertising email between 9pm and 8am, you need separate advance consent to be contacted during that window. This check only looks at text, so it doesn’t check timing.

This check isn’t legal advice. It only looks at the requirements that can be verified from the text itself.

Need to check hundreds of companies at once?

When Outreach collects companies by keyword, it checks whether each address is live first, and you’re not charged credits for addresses that don’t exist. The ad-disclosure tag and opt-out instructions are also added to every email automatically.
