Every number, verifiable.
Live fleet health, sourced from the production database, refreshed every 5 minutes. No projections, no hardcoded claims. If a number on inboxlee.com cannot be backed by what you see here, it does not belong on the marketing site.
Synced syncingLast mailbox provisioned -0 shipped this week
Every mailbox ships with the full auth stack.
The four DNS records cold-email infrastructure actually needs - applied automatically, verified continuously, never edited by you. Drop any inboxlee.com customer domain into a DNS lookup tool to verify.
~94% industry baseline
Validity Sender Score benchmarks - cold mail authenticated with DKIM + SPF + DMARC. Every Inboxlee mailbox ships with that stack so the baseline applies fleet-wide on day one. Your own placement = baseline × (your reputation × your list quality × your copy) - we ship the infrastructure floor; the rest is on you.
Note: Inboxlee does not currently operate fleet-wide seed tests. The number above is the published industry rate for the authentication footprint, not an internal measurement. When seed-test infrastructure ships, this card will flip to a measured number.

Sourced benchmarks, Inboxlee in the same row.
Every industry number below cites a public report. The Inboxlee column is either a live fleet metric or an operational fact about how the product works. Where we do not yet measure something publicly, the column reads tracking soon rather than a fabricated number.
| Metric | Industry baseline | Inboxlee fleet |
|---|---|---|
Cold email inbox placement rate Share of cold email sends that land in the recipient inbox rather than spam or missing. Median across 200B+ tracked sends. | 76-83% | tracking soon no fabricated number |
Senders with SPF + DKIM + DMARC fully configured Percentage of B2B domains with all three authentication standards correctly configured. Inboxlee provisions all three automatically on every new domain. | ~38% | 100% ↑ ahead of baseline |
Cold email mailbox attrition rate (quarterly) Percentage of cold email mailboxes that get suspended or burned per quarter from normal sending. Plan for replacement cohorts. | 5-15% | tracking soon no fabricated number |
Median time to provision a Google Workspace mailbox (manual) Industry baseline for manually provisioning a Google Workspace mailbox: register domain, configure DNS, create user, apply SPF/DKIM/DMARC. Inboxlee automates the full chain. | 15-30 minutes Google Workspace Admin Console workflow timing (industry observation) · 2025 | ~90s ↑ ahead of baseline |
B2B sending domains with daily blacklist monitoring Most cold email senders never check whether their domains have landed on Spamhaus, Barracuda, SORBS, or Spamcop until reply rates collapse. Inboxlee runs daily checks across all four bundled. | < 20% | 100% ↑ ahead of baseline |
