How it works
A short walkthrough of the Trust Center workflow.
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.
Step 2
Connect your mailbox
Link Gmail or Microsoft 365. We scan recent mail and build your personalized wow dashboard with real Safe, Suspicious, and Dangerous examples.
Step 3
See what AI found
Claude Haiku explains each message in plain English — threat level, confidence, and what to do next in Monitor.
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 blocked.
Step 5
Upgrade when ready
Move to Core, Pro, or Elite for full inbox screening, Mailguard Advisor, 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 side panel inside Gmail and Microsoft Outlook. See Safe, Suspicious, or Dangerous on the message you are reading — 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 inbox hold.
Core
Core+: Mailguard Companion included — full reasons, What to do, and Monitor deep links in-client.
Pro & Elite
Pro+: Companion plus Ask why (Mailguard Advisor) inside Gmail & Outlook.
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 mail summaries. Plain-English alerts, no remote control — the mailbox owner still reviews and decides in their own Monitor.
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
- Mailbox owner connects their inbox and invites a trusted helper from Profile.
- Trusted helper sees summaries when dangerous mail is held — and can coach calm next steps.
- No takeover — helpers never open, delete, or release mail. Control stays with the mailbox owner.
Plans & pricing
