About Mailshu - Email Open Signals

Mailshu는 Gmail에서 보낸 메일의 수신 여부를 Gmail 안에서 확인할 수 있는 확장프로그램입니다. • Google 계정 로그인으로 사용자별 기록 분리 • Gmail 작성창에서 메일별 수신 확인 켜기·끄기 • 읽음·읽지 않음 상태와 확인 시각 표시 • 상대방의 별도 설치나 확인 요청 없음 • 메일 본문과 첨부파일은 저장하지 않음 읽음 표시는 메일 속 이미지가 불러와진 기록을 기준으로 합니다. 이미지 차단이나 메일 서비스의 이미지 미리 불러오기로 인해 결과가 누락되거나 실제 열람보다 먼저 표시될 수 있습니다.
