Four keys, all free to sign up:
- OpenAI writes the emails using ChatGPT models. Sign up at platform.openai.com.
- Anthropic writes the emails using Claude models. Pick this or OpenAI, or use both. Sign up at console.anthropic.com.
- Lead Magic finds the missing data on your leads. Sign up at leadmagic.io.
- Million Verifier checks emails are real before you send. Sign up at millionverifier.com.
Paste each into Lead Formatter once. Done.
For a 5,000-lead campaign, using current published rates:
- AI writing costs under $1 with GPT-4o mini, or about $6 with Claude Haiku 4.5. Bigger models like GPT-4o or Claude Sonnet cost more.
- Email verification with Million Verifier is about $30.
- Enrichment with Lead Magic depends what you pull, usually a few pennies per lead.
- LinkedIn description scrapes are included up to 30,000 a month.
One thing worth knowing: the more you top up your OpenAI or Anthropic account, the higher your rate limits get. A brand-new API account is slower than one you've spent $500 on. That means Lead Formatter runs faster the more you've paid your AI provider.
