// HEADLINE NUMBERS

The four hardest-to-fake deliverability stats in the category.

[01] INBOX PLACEMENT
94.2%

Average placement across 41,000+ monitored sending domains, verified daily by independent seed-list testing.

[02] SENDING UPTIME
99.97%

Trailing 24-month uptime on our public status page — paired with a contractual SLA no other cold email vendor publishes.

[03] QUARTERLY THROUGHPUT
2.1B

Email sends processed across the customer base per quarter, Q1 2026 actual — not a modeled projection.

[04] MONITORED DOMAINS
41k+

Sending domains under continuous deliverability monitoring — the largest live cohort tracked by any cold email vendor.

// PUBLIC DELIVERABILITY REPORT

The number is verifiable. The methodology is public.

Every claim on this page is traceable to the BandagBullet Public Deliverability Report — refreshed daily, downloadable as CSV, with methodology notes attached to every column.

  • Independent seed-list testing. We do not test our own infrastructure. A third-party seed network places mail across 28 mailbox providers, including Gmail, Outlook, Yahoo, and the major European ESPs.
  • Daily refresh at 00:00 UTC. Yesterday's numbers stay visible for 30 days so you can spot drift, not just see today's snapshot.
  • Raw CSV export. Pull per-domain, per-provider, per-day breakdowns — no login, no NDA, no "request access" form.
  • Methodology column on every row. Each data point shows which seed account, which sending pattern, and which mailbox provider generated the result.

// BULLET WARMING PROTOCOL · PATENT-PENDING

From new domain to 2.3× baseline deliverability in 11 days.

Bullet Warming is not a "send a few emails and pray" warmup. It is an engineered four-phase protocol that ramps volume, cadence, and content complexity in lockstep with the receiving providers' reputation signals.

  1. 01

    Identity & DNS hardening

    SPF, DKIM, DMARC, and the lesser-published BIMI / TLS-RPT records are configured with alignment checks across every subdomain. We reject the ~12% of incoming domains that fail pre-flight alignment, because no warmup fixes broken identity.

    Reputation seed phase

    Mail is exchanged against a curated seed network across 28 mailbox providers at low daily volume. Engagement signals (opens, replies, moves out of Spam) are fed back into the next-day cadence model.

    Adaptive ramp

    Daily send volume scales based on the previous 24h placement score. Domains above 88% placement ramp faster; domains in the 70–88% band hold volume; anything below 70% is paused automatically for cooling.

    Production handoff

    Domain graduates into the live outbound queue once two consecutive days hold ≥ 90% placement. The warmup cohort keeps a light feedback loop running in the background for another 30 days.

// PER-RECIPIENT SPAM-CHECK SCORING

We block bad sends before they leave your domain.

Every individual recipient on every campaign is scored the moment the send is queued — across content, sending pattern, recipient reputation, and historical engagement. Sends that fall below your threshold are held, not shipped.

  • 11.4% of outbound mail blocked per customer, on average. The median BandagBullet customer would have shipped 11.4% more emails last quarter under a non-scoring tool. Those sends would have dragged their domain into the watch tier within 21 days.
  • Four-axis scoring, per recipient. Content heuristics (link density, image-to-text ratio, spam-trigger phrases) + sending pattern (volume, cadence, time-of-day) + recipient risk (role address, role-vs-name, prior bounce) + historical engagement (last open, last reply, last unsubscribe).
  • Override is allowed. Override is logged. Sales reps can force-send a flagged recipient. The override is written to an immutable audit log so RevOps can review every exception without blocking the SDR's workflow.
