Rules for webinar invitation subject lines

• Promise a takeaway, not a topic ('cut CAC in half', not 'growth webinar').
• Name the speaker if they carry authority in your niche.
• Date and 'live' in the preview text; keep the subject about value.
• A reminder-day resend with a fresh subject lifts attendance.
