    To address your request regarding the restoration of your email sending capabilities in Azure Communication Services due to sender reputation issues, here are some steps and considerations:

    1. Review of Sender Reputation: Ensure that you have thoroughly analyzed your email delivery reports to identify any patterns of bounces or complaints. This analysis is crucial for understanding the root causes of the reputation issues.
    2. Clean Mailing List: It’s good that you have cleaned your mailing list by removing invalid or bounced addresses. Regularly maintaining a healthy contact list is essential for improving sender reputation.
    3. Unsubscribe Management: Implementing a robust unsubscribe handling process is important. Make sure that your unsubscribe links are functional and clearly communicated to recipients, allowing them to opt-out easily if they choose.
    4. Warm-Up Strategy: Once your sending capabilities are restored, implementing a warm-up strategy is advisable. This involves gradually increasing your email sending volume to build a positive sender reputation over time.
    5. Monitoring and Compliance: Continuously monitor your email delivery performance and be proactive in addressing any issues that arise. Following best practices for email compliance and user engagement will help maintain a good sender reputation moving forward.

    For further assistance, you may consider reaching out to Azure support for a detailed review of your account and specific guidance tailored to your situation.
