In many Korean workplaces, email is treated as an official record, while KakaoTalk or an internal messenger is used for quick confirmation and collaboration. Foreign employees do not need perfect Korean to communicate well: a clear subject, respectful form of address, a specific deadline, and polite language are the safest foundation.
Make the subject line specific
Avoid a vague subject such as “Hello.” Use a format like “[Project A] September Progress Report (Attached)” so the recipient can identify the project, purpose, and attachment immediately. In a Korean greeting, add 님 (-nim) after a person’s name or title, as in “부장님, 안녕하세요” or “홍길동님, 안녕하세요.” Organize the body in this order: background, request, deadline, and closing, followed by a signature with your name, position, and contact details.
A practical email checklist
- Introduce your team and name, then explain why you are writing in one or two sentences.
- State the required action and deadline precisely, for example, “Please confirm whether you can attend by October 5.”
- Close with a polite phrase such as 감사합니다, 잘 부탁드립니다, or “Please let me know if you have any questions.”
Be prompt and polite on messenger
Companies may use KakaoTalk, Slack, Microsoft Teams, or JANDI, so first check the rules for public channels and direct messages. If you cannot answer immediately, acknowledge receipt and give a response time, such as “I have checked this and will reply by 3 p.m.” Use honorific language at first, even with friendly colleagues, and avoid casual Korean abbreviations such as ㅇㅋ or ㄱㄱ and excessive emojis. Important decisions, approvals, and schedule changes should remain in email or a shared channel so the team can refer to them later.
Key takeaway
A descriptive subject, the respectful -nim suffix, a body that moves from context to request and deadline, and a quick acknowledgment will prevent most common communication mistakes in a Korean office.
