Summary
Legal timeframes for processing unsubscribe requests vary across countries. CAN-SPAM (US) and CASL (Canada) allow up to 10 business days, although prompt action is strongly recommended. GDPR (UK) requires processing 'without undue delay,' typically within a few days. Australia mandates action within 5 business days. Best practices emphasize immediate or same-day processing to protect sender reputation. It's also a CAN-SPAM violation to move unsubscribed addresses to another active list. Challenges exist in quickly updating unsubscribes, particularly with data warehouses and multiple ESPs. Mailbox providers generally expect faster processing than the legal maximums.
Key findings
- US (CAN-SPAM): Allows up to 10 business days for processing unsubscribes, but faster action is preferable.
- Canada (CASL): Requires processing without delay, but no later than 10 business days.
- UK (GDPR): Requires processing 'without undue delay,' typically within a few days.
- Australia: Unsubscribe requests must be actioned within 5 business days.
- Reputation Impact: Slow unsubscribe processing can damage sender reputation and increase spam complaints.
- Multi-ESP: Moving unsubscribes between multiple ESPs must happen to legally comply.
- Data Warehouses: Failing to supress unsubscribes in MTAs when pulling from data warehouses causes delays.
Key considerations
- Immediate Action: Strive for immediate or same-day unsubscribe processing whenever possible.
- Global Compliance: Be aware of and comply with the specific unsubscribe regulations in each country you send to.
- Data Management: Ensure efficient data management processes to quickly update unsubscribes across all systems.
- Reputation Protection: Prioritize timely unsubscribe processing to protect your sender reputation and avoid spam filters.
