ToolTrusted is the independent Email Infrastructure Intelligence Platform. It measures the full posture that decides whether your email works — authentication (SPF, DKIM, DMARC, BIMI), infrastructure (MX, MTA-STS, TLS-RPT, DNSSEC) and reputation — then keeps watching it, remembers every change, and tells you in plain language what changed, why it matters, and exactly what to do. It is the layer between “I hope our email is fine” and “I know, and I can prove it.”
Measured. Remembered. Explained.
The platform is built on one idea: your email posture is measured continuously, stored as immutable history, and every verdict is regenerated from that history by a deterministic rule. That is what lets ToolTrusted do three things a one-off checker or a report-ingesting tool cannot.
The intelligence layer
One capability leads naturally to the next — from watching your posture, to understanding it, to acting on it, to proving it, to automating it. The free Email Health Check and weekly monitoring are the doorway; the capabilities below are what Premium unlocks.
We re-check your posture on a schedule and catch drift — a broken SPF include, a DMARC downgrade, a new blocklisting — the day it happens, with contextual email alerts.
The event story of your domain: every meaningful change in order, no-change stretches collapsed, each entry explained. A permanent, replayable record.
Where each signal is heading, plus historical analytics: MTTR, recurring and flapping issues, and a deterministic reliability verdict with its drivers.
Every issue as a coherent lifecycle — opened, updated, resolved, reopened — with auto-derived lessons (chronic, flapping, first-pass) drawn from its full history.
The exact fixes, ranked by impact and sequenced into a plan — each with why it matters, the action to take, and a guide link. Deterministic and evidence-backed.
How your posture compares to a real 10,000-domain population — overall and by TLD. Honest adoption data, not a fabricated percentile.
The intelligence delivered on a schedule, plus a PII-free, verifiable public status page you can share — a built-in way to show clients and colleagues the posture is sound.
Your posture as JSON on demand, and outbound webhooks and Slack messages that fire the moment something changes — so the intelligence lands where your team already works.
Roll every workspace into one executive view — verdict, open issues and priorities across all your domains, with org-scoped API access and named team keys. Built for agencies.
Where free ends and operations begin
Free is the checker that remembers — score any domain, save reports, keep a Workspace of up to three domains, and get weekly monitoring with alerts. It is genuinely useful, and it is the proof. Premium is your always-on email infrastructure operations — the whole intelligence layer above, plus scale (25 domains, daily checks, 365-day history) and white-label reports. The upgrade trigger isn’t a limit you hit; it’s the moment you need to operate your infrastructure, not just check it. See pricing →
Independent, deterministic, and able to show its work
ToolTrusted measures only real signals — no fabricated metrics, and no claim to measure actual inbox placement (we measure the infrastructure that determines it). Every verdict is reproducible and traceable to a documented rule, grounded in the real email standards and the latest Gmail, Yahoo and Microsoft sender requirements. And because we sell you nothing to fix, our analysis has no commercial destination. See exactly how we test, and the original 10,000-domain research behind the benchmark.
