Why was an email with the updated Client Master Report (CMR) sent by Zerodha?

An email with the updated CMR is sent for the following reasons:

• A new demat account was opened with Zerodha.
• Account details were recently modified, such as a name change, address change, mobile number change, email change, updating income details or any other change in the demat account.
• The demat account was converted to BSDA or NON-BSDA. See What is a Basic Services Demat Account (BSDA) and how can one be opened at Zerodha?
• As per the SEBI circular (PDF) the updated CMR is emailed whenever a demat account is mapped or unmapped from a trading account.
• The Zerodha account was closed.
