Notifying your ESP can typically be done through various channels:
Customer Support: Most ESPs have dedicated customer support teams that can assist with any changes or queries. Contacting them directly is often the quickest way to inform them of important updates. Account Manager: If you have a designated account manager, they can be a valuable resource for communicating any significant changes. Email or Ticket System: Many ESPs offer email or ticket-based support systems where you can log your requests or updates.
