Cold email, tuned live.

Editable template on the left. Three sample prospects on the right re-render live as you type. Variables like {{first_name}} and {{firm}} are highlighted so you can see what's substituting. When the template lands across all three sample inputs, you have your send-ready copy.

Edit SAMPLES array — each represents one prospect with its variable values. Variables in the template use {{double_braces}}. Live render is a simple regex replace.

const SAMPLES = [
  { first_name: "Lily", firm: "Aspen Wealth",
    aum: "$1.4B", recent_signal: "a Schwab integration partner",
    pain_1: "Manual sub-doc work eating ops hours", /* ... */ },
  // ... etc
];

When to use this

Anytime you have a template + variable inputs + want to see "does it land?" across multiple profiles. Beats writing 3 separate drafts; the variables force you to think structurally.
