In email marketing, the subject line is your first — and sometimes only — chance to earn a reader’s attention. Even the best-written email will not perform if the subject line fails to spark curiosity or communicate value. Low open rates usually start with weak subjects, which means poor engagement, missed conversions, and wasted campaign effort.
