Enable the Spam inbox if you want suspicious emails to be isolated for review instead of mixing with your main queue.

Crisp already blocks the most severe email abuse automatically, but some suspicious emails can still be delivered into a reviewable Spam inbox. This gives your team a safer way to inspect questionable messages without letting them clutter the main Inbox.

What goes to the Spam inbox

The Spam inbox is meant for emails that look suspicious but are still worth reviewing manually.

Typical cases include:

• Spam with a moderate or high risk level
• Emails that fail DMARC checks

Emails sent from servers without basic authentication records such as SPF or DKIM can be rejected entirely and may never appear in the Spam inbox.

Enable the Spam inbox

Go to Settings → Email Settings → Email Behaviour and enable Send emails that might be junk to the Spam inbox.

Once enabled, suspicious emails appear in a dedicated Spam inbox inside the Crisp Inbox.

Review or restore suspicious emails

From the Spam inbox, your team can inspect each conversation and decide what should happen next.

From there, you can:

• Accept the message → it is moved back to the main inbox
• Reject the message → it stays treated as spam

This gives you a clean safety layer without losing visibility on borderline cases.

Block spam automatically with Triage

If you want to go beyond Crisp's built-in detection, combine the Spam inbox with Automatic Triage.

From Settings → Inbox Settings → Automatic Triage, you can create Block Rules that catch specific senders, domains, keywords, or patterns.
