Crisp takes email security seriously, helping protect customers against spoofing, phishing attempts, and other forms of unwanted email.

While Crisp automatically rejects the most severe spam and emails that fail to comply with basic authentication requirements, some suspicious emails may still be received and redirected to your Spam inbox for review.

This includes:

• Spam of moderate or high level
• Emails failing DMARC checks

Note that emails sent from servers without any SPF record or DKIM signature are automatically rejected and will not appear in the Spam inbox.

Once enabled, suspicious emails will appear in a dedicated Spam inbox within your Crisp inbox.

From there, you can review them and choose whether to:

• Accept them, in which case they will be moved back to your main inbox
• Reject them, if they are indeed unwanted

Blocking spam automatically with Triage

In addition to Crisp’s built-in spam detection, you can also create your own rules to automatically mark conversations as spam using the Triage feature.

This is useful if you want to block specific senders, domains, keywords, or message patterns yourself.

To do so, navigate to:

Settings > Inbox Settings > Automatic Triage

There, you can create Block Rules that will automatically:

• Mark matching conversations as spam
• Or drop them permanently

This gives you more control over what should be considered unwanted in your workspace.
