The ToolTrusted Platform: Email Health Monitoring

Email health monitoring keeps your whole domain working — and ToolTrusted is the independent Email Health Platform built to do it, continuously. 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.”

Together, that is email health monitoring in one place — email infrastructure monitoring, DMARC monitoring and domain reputation monitoring included — a single email deliverability platform, so nothing drifts unnoticed.

Measured. Remembered. Explained.

The platform is built on one idea behind all email health monitoring: 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.

Email health monitoring is the thread that ties the platform together: one engine watches every record and feeds the timeline, incidents and recommendations. Because email health monitoring runs continuously, you can start free with the Email Health Check and upgrade to daily continuous monitoring when you are ready.

Email health monitoring: 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 is the doorway and costs nothing, forever; the capabilities below are the Workspace — the platform you subscribe to.

Where the free tools end and the email deliverability platform begins

The tools are free, forever, with no account — score any domain as often as you like, read the complete explained report, and share it at a permalink. We never blur the result or hold back the fixes. That is how you judge whether our measurements are worth trusting, and it costs you nothing.

The Workspace is the platform you subscribe to — because a Health Check tells you the state of your domain right now, and the thing that actually hurts is what changes next. DNS gets edited, keys rotate, providers migrate, IPs get listed; email breaks silently and nobody notices until mail stops landing. That is why email health monitoring runs on a schedule.

Starter (.99/mo) watches every week and tells you the moment it breaks, why, and what to fix first. Pro (9) adds daily checks and everything you need to prove it — incident history, reliability analytics, benchmarks, scheduled reports, the API. Agency (9) is for when the domains belong to your clients — white-label and a portfolio pane.

You never upgrade because you hit a limit; you upgrade because the job changed. See plans →

Independent, deterministic, and able to show its work

ToolTrusted email health monitoring 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 — like DMARC (RFC 7489) — 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.
