ToolTrusted is the independent Email Infrastructure Intelligence Platform — not a one-off checker. It turns a 30-second scan into continuous intelligence about your domain: measured, explained, remembered, and acted on. Here is the whole journey, end to end.
The journey: check → keep → watch → understand → act → prove → automate

What the Email Health Score measures
The score — your entry metric — is the output of one engine, built only from signals we actually measure. No invented deliverability number. Each dimension maps to real DNS and reputation checks you can drill into on the free tools page, and the weighting is documented on How We Test.
Frequently asked questions
Is the Email Health Check really free?
Yes. The check, the report, saving to a Workspace, history and weekly monitoring are all free — no credit card, no trial timer. Premium unlocks the full intelligence layer — trends, historical analytics, incidents, recommendations, benchmarking, scheduled reports, the REST API, portfolio management and automation — for people who need to operate their email infrastructure, not just check it.
Do I need an account to run a check?
No. You can run a check and get your full report with no account at all. When you want to keep your report and track it over time, you save it to a Workspace using a passwordless magic link — there are no passwords to create or remember.
How often does monitoring run?
Free monitoring re-scans your domains weekly and emails you only when something meaningful changes — a regression or a broken record — with a plain-English explanation and the fix. Premium unlocks daily monitoring for faster detection.
Does the score claim to measure inbox placement?
No — and that’s deliberate. We don’t run inbox seed tests, so we don’t fabricate a deliverability score. ToolTrusted measures your authentication, infrastructure, security and reputation posture — the infrastructure that determines whether mailbox providers trust your mail — and explains how it influences placement. We measure the cause, not the symptom.
