AI Email Finder: How to Discover Any Business Email with Smart Permutation

The Problem with Finding Business Emails

You found the perfect buyer for your products. You know their name, their company, their website. But you don't have their email address.

Traditional email finders like Hunter.io charge per lookup. Apollo.io requires expensive subscriptions. And they still miss many international business emails — especially for companies in Asia, Middle East, and Latin America.

How AI Email Permutation Works

Instead of relying on a pre-built database, smart email permutation generates all possible email addresses and verifies them in real-time:

14+ Name Patterns

Given a name like John Smith at acme-trading.com, the system generates:

  • john@acme-trading.com
  • john.smith@acme-trading.com
  • jsmith@acme-trading.com
  • j.smith@acme-trading.com
  • smith.john@acme-trading.com
  • johns@acme-trading.com
  • john_smith@acme-trading.com
  • ...and 7+ more patterns

30+ Common Role Prefixes

Even without a name, the system tries role-based addresses:

  • info@, sales@, contact@, admin@
  • procurement@, import@, export@, trade@
  • ceo@, director@, manager@

SMTP Verification

Each candidate email is verified via:

  1. DNS MX lookup — Confirms the domain has a mail server
  2. SMTP RCPT TO — Checks if the mailbox accepts mail
  3. Catch-all detection — Identifies domains that accept all addresses

Using Email Permutation in PulseAgent

PulseAgent's Email Permutator tool is built into every AI agent. Simply ask your agent:

"Find email addresses for the procurement team at acme-trading.com. Try names: John Smith, Maria Garcia, Li Wei."

The agent returns verified emails with confidence scores in seconds.

Free, No API Key Required

Unlike Hunter.io ($49/mo) or Apollo.io ($49/mo), PulseAgent's email permutator requires zero external API keys. It works directly with DNS and SMTP — completely free and unlimited.
