Suppression Lists & Compliance
Suppression lists prevent emails from being sent to specific addresses or domains:
Managing Your Blocklist:
1) Go to Settings > Blocklist tab
2) Add entries by type:
• Email suppression — Block a specific email address (e.g., [email protected])
• Domain suppression — Block an entire domain (e.g., competitor.com blocks all @competitor.com addresses)
3) Each entry can have an optional reason for tracking
Automatic Suppression:
- Bounced emails are auto-added (source: 'bounce')
- Unsubscribed prospects are auto-added (source: 'unsubscribe')
- Spam complaints are auto-added (source: 'complaint')
- Manual entries show source: 'manual'
Enforcement:
- During CSV import: any email matching a suppression entry is automatically skipped and counted as 'suppressed'
- During campaign sending: suppressed prospects are blocked from receiving emails
- Domain-level suppression matches all emails at that domain
- Case-insensitive matching
CAN-SPAM Compliance:
- Every campaign email includes an unsubscribe link in the footer
- RFC-compliant List-Unsubscribe and List-Unsubscribe-Post headers
- Unsubscribe requests are processed immediately
- Physical address should be included in your email footer
GDPR Compliance:
- Respect opt-out requests promptly
- Maintain your suppression list as your 'do not contact' registry
- Consider adding a privacy policy link to your email footer
- Data access and deletion requests should be handled through your workspace settings
Best Practice: Regularly review and clean your suppression list. Add competitor domains, existing customer domains, and known bad addresses proactively.
