Rules for cold outreach email headlines

• Keep it 2-4 words so it reads as a real colleague's email.
• Reference something specific to them, not your product.
• Skip the pitch in the subject; earn the open, sell in the body.
• Avoid spammy triggers ('free', 'guarantee', all caps) that hit filters.
