Authentication footprint

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.

Placement context

~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.

How Inboxlee compares

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.
