📝 Email Templates: Write Once, Reuse Many Times + Auto Variable Substitution (Every Email Looks Like 1-on-1)
Email Templates = write an outreach email once, then apply it directly in Mass Email / Compose. Combined with variables (`{First Name}` `{Company}` `{Title}` etc.), each email is **auto-replaced with that customer's real data** — 1000 customers receive 1000 emails that 'look written just for them'. This is the core of mass-send-single-display.
