What makes these work

Cohort-course subjects need to balance scarcity (real, not faked) with audience qualification (who it's for, who it's not). '{{cohortName}} opens Monday — 32 seats' is honest, specific, and pre-qualifies. The 'who it's not for' framing in subject ('{{cohortName}} — and who shouldn't join') is unusual and effective; it filters the audience and signals seriousness. Avoid 'transform your career' subjects — they're the high-volume noise this category competes with. Specific deliverables ('You'll ship a {{specificThing}} by week 4') outperform aspirational claims.
