Try Free — MailguardAI ETDR screens your inbox and shows real Message Risk in minutes

Email Threat Detection & Response — in your mailbox.

MailguardAI-247 ETDR screens Gmail and Microsoft 365 with Claude Haiku across Message, Account, and Fraud risk. Connect a mailbox, get a personalized wow dashboard in minutes, and act on Safe, Suspicious, or Dangerous mail from the MailguardAI banner — plain English, mailbox-first.

We don't just detect threats — we train you to respond.

ETDR pairs Message Risk screening with optional quarterly phishing drills in the Trust Center — so you learn what to do, not just what was flagged.

Free: last 7 days scanned · Paid plans: full inbox + 7-day trial

ETDR · Email Threat Detection & Response

Three risk planes. One mailbox-first response.

Primary actions happen in your mailbox on the MailguardAI stamp. The Trust Center Monitor is an optional exception queue and history — not required to release mail.

  • Message Risk

    Incoming mail is screened once and labeled Safe, Suspicious, or Dangerous. Act with Allow / Trust, Block, or Not safe? on the MailguardAI banner in Gmail or Outlook.

  • Account Risk

    Mailbox takeover signals — forwarding, rules, MFA posture where available, unusual sign-in alerts, and travel/device baselines on Microsoft work/school.

  • Fraud Risk

    Business-email-compromise style patterns (wire, payroll, vendor, gift-card) with context such as urgency and compromised account posture (Elite).

How it works

From Free Message Risk preview to full ETDR in the Trust Center.

  1. Step 1

    Sign in — start Free

    Create your account in under a minute. Choose Free — no credit card — and connect one Gmail or Microsoft 365 mailbox.

  2. Step 2

    Connect your mailbox

    Link Gmail or Microsoft 365. We screen recent mail and build your wow dashboard with real Message Risk examples — Safe, Suspicious, and Dangerous.

  3. Step 3

    See ETDR on your mail

    Claude Haiku explains Message Risk in plain English. Act from the MailguardAI banner in your mailbox — Trust Center Monitor is optional after you act.

  4. Step 4

    Practice on real drills

    Opt in to quarterly phishing drills — safe simulations with a short quiz so you learn what scammers want, not just what we flagged.

  5. Step 5

    Upgrade when ready

    Core, Pro, or Elite unlock full ETDR — Companion, Account Protection, Fraud Risk on Elite, and multiple mailboxes — with a 7-day trial on paid plans.

Mailguard Companion

Explanations where you already read mail — Gmail and Outlook.

Mailguard Companion is the ETDR side panel inside Gmail and Microsoft Outlook. See Message Risk (Safe, Suspicious, or Dangerous) on the message you are reading — plus Account or Fraud secondary lines when elevated — without opening another tab. Full Companion is included on Core and above; Free gets a limited teaser.

Free

Free: verdict + Should I open this? in Gmail/Outlook — upgrade to Core for the full pane and mailbox stamps.

Core

Core+: Mailguard Companion included — full reasons, What to do, Account/Fraud lines when elevated, and Trust Center links after you act.

Pro & Elite

Pro+: Companion plus Ask why (Mailguard Advisor) inside Gmail & Outlook — with Account Protection in the Trust Center.

Companion is included on paid plans — not a separate tier. Screening and hold still run on MailguardAI servers; the pane explains mail where you read it.

Trusted Helper

Help someone you trust review risky mail — without taking over their inbox.

Trusted Helper lets a linked helper see held Suspicious and Dangerous Message Risk summaries. Plain-English alerts, no remote control — the mailbox owner still decides via Allow / Trust or Block on the MailguardAI banner (ETDR stays mailbox-first).

Pro supports up to 3 mailboxes plus Mailguard Advisor — protect more than one inbox and stay in the loop with Trusted Helper.

How it works

  1. Mailbox owner connects their inbox and invites a trusted helper from Profile.
  2. Trusted helper sees summaries when dangerous mail is held — and can coach calm next steps.
  3. No takeover — helpers never open, delete, or release mail. Control stays with the mailbox owner.
