Graymail Protection

INKY identifies legitimate bulk mail (newsletters, promotions, notifications) and moves it aside so users can focus on important messages. Unlike spam or phishing, graymail is mail users may have subscribed to but doesn't need immediate attention.

Enable Detection

Admin Center > Graymail Protection

Toggle on to flag graymail with the Graymail threat category. Detection analyzes headers, links, body text, and sending patterns.

Graymail result bucket: Set to "Caution (Spam)" by default. If graymail contains actual threats (phishing, malware), INKY escalates the threat level appropriately.

Automatic Folder Rules

INKY can create inbox rules to automatically move graymail to a dedicated folder, keeping inboxes clean without blocking legitimate mail.

Two Setup Options

1. User-Managed Rules

Users create their own filters to organize graymail.

Google Workspace:

  1. In Gmail, click Filter button

  2. Has the words: [INKY:Graymail]

  3. Create filter

  4. Select: Skip the Inbox + Apply label: Graymail (create new)

  5. Check "Also apply filter to matching conversations"

  6. Create filter

Microsoft 365:
Users can enable graymail filtering from their User Center Graymail Protection - INKY

2. Admin-Managed (Automatic)

Enable "Automatically setup inbox rules to move Graymail messages to a folder" in Admin Center.

Requirements:

  • Directory API Access enabled

  • Remediation API Access enabled

  • Graymail configured to deliver to inbox (not quarantine)

  • Rules created nightly for all licensed mailboxes

When to use automatic setup: Reduce support tickets by handling graymail organization centrally.
When to use user-managed: Give users control over their own graymail handling preferences.

Key Distinction

Graymail isn't spam or phishing—it's legitimate bulk mail users may have subscribed to. INKY moves it aside rather than blocking it, so users can review when convenient.
