Find the right contact
A useful message starts with contact selection: manager, team lead, recruiter, senior IC, or warm referral source.

Write for the role
Each guide ties the message to role-specific proof: pipelines, roadmaps, systems, React, reliability, AI evals, or product metrics.
Respect the timing
Follow-up works best when it is paced like a professional signal, not pressure. The timing sections keep the cadence simple.

Browse by outreach intent.
Start with the role guide if you are unsure. Use the hiring-manager, recruiter, follow-up, and referral pages when you already know the outreach path.
