Best practices to secure Gmail and Outlook against fraudulent emails

Your teams live in Gmail and Outlook all day. A single rushed click can trigger wire fraud or account takeover. Combine platform controls with Mailqor to build a layered defense anyone can follow.

Enforce identity and access hygiene

• Require phishing-resistant MFA for Google and Microsoft 365 accounts.
• Monitor dormant accounts and revoke sessions when employees leave.
• Use conditional access rules to limit risky locations or unmanaged devices.

Harden mailbox policies

• Turn on advanced phishing protection in Google Workspace and Microsoft Defender for Office 365.
• Block auto-forwarding to external domains unless explicitly approved.
• Require secure defaults for new shared mailboxes and service accounts.

Deploy Mailqor badges everywhere

• Install the extension from the Chrome Web Store so Gmail and Outlook users see the same trust signal.
• Educate teams on what Verified, Unverified, and Suspicious mean before a crisis happens.
• Use Mailqor analytics to spot departments flooded by risky senders.

Build rapid triage workflows

• Pin Mailqor's "Check risk" action so anyone can escalate suspicious threads.
• Connect alerts to Slack or Teams channels where security can jump in quickly.
• Provide templates for finance and support to pause transactions until a badge shows Verified.

Train continuously

• Run quarterly phishing simulations and tie results back to Mailqor indicators.
• Share short videos showing where to find sender details in both Gmail and Outlook.
• Celebrate good catches to keep adoption high.

Conclusion: make trust visible at the inbox

Combining platform controls with Mailqor's badge turns inbox security into a shared habit. When every employee knows how to authenticate senders and escalate anomalies, fraudulent emails stop being silent threats.
