Sending messages from the same number on behalf of different clients is generally not recommended due to potential regulatory, compliance, and customer trust issues. Many messaging platforms and local regulations require that the sender's identity remains consistent to avoid confusion or potential deception. Using the same number for multiple clients could lead to issues with spam filters, erosion of customer trust, and potential breaches of opt-in agreements. The best practice is to use dedicated numbers for each client to ensure clear and consistent communication, or to leverage platform features like sub-accounts, which allow for effective management of multiple clients while maintaining compliance and brand integrity. This approach not only aligns with best practices but also ensures a better customer experience by preserving clear brand communication.

I understand, thank you very much for the explanation, I will study how to open a sub-account, can you tell me where I can start?
