Despite your best efforts, some subscribers may still remain inactive. In such cases, consider the following actions:
Suppress or Remove: Move these subscribers to a suppression list or remove them entirely to maintain list hygiene. Segment for Future Campaigns: Keep them in a separate segment for occasional re-engagement attempts, but don't include them in your regular sends. Multi-Channel Engagement: Try reaching out through other channels like social media or retargeting ads to rekindle their interest.
