Rule types

Domain rules

Allow or block emails from specific domains.

  • Block: guerrillamail.com
  • Allow: yourcompany.com
  • Block: *.tempmail.net

IP rules

Block email addresses associated with specific IP ranges or known bad actors.

  • Block IPs associated with spam infrastructure

Country rules

Enforce geographic restrictions on email signups.

  • Block signups from specific countries
  • Allow only certain regions

Actions

Allow

Override automatic block detections for trusted domains or addresses. Useful for known partners or internal addresses that would otherwise be flagged.

Block

Force a Block verdict for any email matching the rule, regardless of what automatic scanning detects. Useful for enforcing geographic or domain restrictions.

How rules are applied

Rules are evaluated before automatic scanning verdicts. A matching Allow rule overrides a detection; a matching Block rule forces a Block verdict. Rules are applied in order of specificity — domain rules take precedence over country rules.

Managing rules

Create, edit, and delete rules from the Email Rules section of your dashboard. Rules are shared across your workspace and apply to all email scans — whether performed via the web interface or the API.
