Most cold email tools send from shared bulk infrastructure. Your emails land in Promotions or Spam before anyone reads them. Preacher is different. It fetches each company's website, uses AI to write a unique personalised paragraph per contact, then sends from your real Gmail or Outlook address via SMTP, not a shared bulk sender. The result: 0% spam rate across 20,435 emails sent. 12% reply rate vs the 3–5% industry average.
