I happened to come across probably the only expat tech K-blog which has a lot of tips for people to check out. The blogger’s latest tip is how to send and receive Naver mail in your Gmail account:
When you’ve created your Naver account, you may decide that using Naver’s webmail client (네이버 메일) is difficult or bothersome, because it is entirely in Korean, and a bit cluttered. I personally prefer sending/receiving my Naver Mail through my G-mail account.
G-Mail has a setting to automatically forward all mail to another account, but Naver Mail does not. Worry not; it’s easy to get all your Naver Mail in G-mail using POP3. The process is super simple. [10 Won Tips]
