Customized training should not be a one-time event. Continuous improvement can be ensured by:
1. Feedback Mechanism: Regularly collect feedback from participants to identify areas for improvement. 2. Ongoing Support: Provide follow-up sessions and resources to reinforce learning. 3. Performance Monitoring: Track the implementation of strategies and their impact on performance. 4. Updated Content: Keep the training content up-to-date with the latest trends and best practices in email marketing.
