발송 전 (Balsong Jeon)

Balsong Jeon is a free, Korean-language browser tool for checking recipient CSV files before sending personalized messages. It flags missing template values and, when you choose an identifier column, missing or duplicate identifiers. Preview one substituted message, fix one CSV cell at a time, recheck immediately, and download a corrected UTF-8 CSV with the original row and column order. Files stay in your browser. Optional legacy Kakao Personalized Message x Reach checks are separate from the default, platform-neutral CSV checks. This tool does not send messages, verify consent, or guarantee compatibility with a provider upload format or delivery. A multi-row editing Pro idea at KRW 9,900/month is only a price hypothesis; it and checkout are not available.
