About You

Your Name

What You Do Be specific. "Food and product photographer," "Webflow developer for architects," "bookkeeping for restaurants."

Your Location City and state. Local clients often respond to local senders.

Website or Response URL Portfolio, booking page, or contact form.

Where You Are

Mailing Address (optional) US law (CAN-SPAM) requires a physical address in commercial email. A PO box works.

Proof You Can Point To (optional) A real past project and what came of it. If you fill this in, the Proof email uses it. If you leave it blank, the Proof email gets an [INSERT] placeholder for you to fill before sending. The tool never invents past work.

Your Voice (optional) Paste an email you wrote and liked. The emails will match its sentence length, formality, and habits, not its content.

End each email with a plain, easy way out ("If this isn't a fit, just say so and I won't follow up"). Recommended for cold email.

About Your Target Client

Client Name Person or company you're writing to.

Client Industry

What You're Offering Them The specific thing you'd propose. "A half-day shoot for their fall catalog," "a site audit and redesign plan," "monthly books and a quarterly review."

What Do You Know About This Client? This is the most important field. The emails are built from it. Include their current marketing, products or services, recent changes, their audience, what you think is missing, why you want to work with them, any personal connection. The tool will not add facts about the client that aren't here.

Their Own Words (optional) Paste text from their website, about page, or a recent post. The emails may use facts from this text, and only from this text, alongside your notes.

The Sequence

Number of Emails

Send Days Comma-separated, one per email. Day 1 is the first send.

Day 1 Date Used only for the calendar file. Send Day 1 falls on this date.

Model The list comes straight from Anthropic and refreshes on its own once a day. Sonnet is a good default. Opus writes the most careful copy and takes longer. Haiku is fastest and cheapest.

Use the fastest model (Haiku) for single-email rewrites, when your account has it.

🔑

This tool runs entirely in your browser. It talks directly to Anthropic and needs your own Anthropic API key. There's no shared account behind it. Click 🔑 API Key above to add yours. Don't have one? Create it at console.anthropic.com/settings/keys.

⚠

Before you send: AI can make mistakes and cannot visit websites. Read every email. Check any industry references, replace any [INSERT] placeholder with your own real experience, and make sure every detail about the client is true. You're responsible for what you send.

Cold email rules: In the US, commercial email must include a physical mailing address and an honest way to opt out, and you must honor opt-outs. Other countries have stricter rules (the UK, EU, and Canada in particular). Check what applies where your client is.
