I am Radha Vembu, the product manager for Zoho Mail and would like to clarify the process we follow:
For troubleshooting issues, we generally refer to email delivery status and activity logs of the user to help us understand the sequence of steps involved for a reported issue.
There are special cases related to spam/abuse for which we request the user to share the email headers/content whichever is applicable to the issue.
There are even rare instances of issues with mail parsing and to debug those cases, we ask our users for the complete original content of the email to simulate the problem.
You can also see our support team asking the users to share the original content of the email for debugging some of the issues, as seen in the links below.

We take the privacy and safeguarding of customer data extremely seriously, and adhere to the strict policies that govern access to user data.
Sorry for making you feel that we access our user's data without permission. That is far from the truth.
