### User-Level Spam Management

**Mark as spam:** Select email → Spam icon (or three dots → Report spam)

Gmail learns your preferences over time.

**Not spam:** Open Spam folder → Select email → Not spam → Move to inbox

And add the sender to contacts — this helps Gmail whitelist them.

### Creating Filters to Bypass Spam

1. Gmail → Settings → See all settings → Filters and blocked addresses

2. Create a new filter → enter From address or domain

3. Actions: tick **Never send it to Spam** → Create filter

Or from a specific email:

Open email → three dots → Filter messages like these → Never spam

### Blocking Senders (User)

Open email from sender → three dots → Block [sender name]

Future emails go to Spam automatically.

### Admin: Allow/Block at Domain Level

admin.google.com → Apps → Google Workspace → Gmail → Spam, phishing, and malware

**Approved senders:** Add trusted email addresses or domains that bypass spam filtering

**Blocked senders:** Add domains or addresses that are always blocked

### Admin: Email Allowlist (IP-Based)

For bypassing spam from known servers (e.g. a CRM or marketing tool):

Gmail → Spam settings → Email allowlist → add IP addresses

### Spam Quarantine

admin.google.com → Reports → Email log search → filter by "Delivery — Spam"

Admins can view and release quarantined messages.

### Inbound Gateway / Third-Party Spam Filter

If you route email through a third-party filter (e.g. Barracuda, Mimecast):

Gmail → Advanced settings → Inbound gateway → Add IP range of the gateway

This prevents Gmail from spam-scoring emails that arrive from your gateway.
