// THE FOUR-PILLAR STACK

Four discrete layers. One auditable inbox placement rate.

Every layer is independently measurable. Every claim is verified against independent seed-list testing across 41,000+ monitored sending domains.

  1. 01 / DOMAINS

    Domains & DNS posture

    Acquire, auto-register, and harden every sending domain with SPF, DKIM, DMARC, and custom return-path alignment — pre-flighted before a single mail is sent.

  4. 04 / COPY INTELLIGENCE

    Copy intelligence & pre-send spam scoring

    Per-recipient spam-check scoring before send blocks an average of 11.4% of outbound mail per customer — the only platform that scores before, not after.

// COPY INTELLIGENCE / PRE-SEND GATE

Score every recipient before a single byte leaves the queue.

BandagBullet is the only cold email platform that runs per-recipient spam-check scoring before send. On average, 11.4% of outbound mail is blocked at the gate — before it can damage domain reputation. No other vendor publishes this number.

  • ✓ Block-by-domain, block-by-recipient, block-by-suppression-list — at dispatch time.
  • ✓ Compliance tooling included for GDPR and CAN-SPAM — account-level controls, not magic auto-mode.
  • ✓ Logged in a per-mail audit trail you can replay for a RevOps postmortem.

// FOUNDER NOTE — LEX MARUYAMA, CEO

“We didn’t build another campaign tool. Every other platform on your shortlist was designed to help marketers send prettier emails. BandagBullet is cold email infrastructure — domains, mailboxes, warmup, and copy intelligence — engineered the way Outreach’s sending stack was engineered when I was there. The SDRs who measure reply rates don’t need a better composer. They need better rails.”

Lex Maruyama Co-founder & CEO · formerly 4th employee, Outreach.io
